Everything You Need to Know about Vertical Spindle Sump Pumps

For many industrial, commercial and domestic processes, there is a need for a pumping solution that is able to effectively allow for drainage of fluids. This might be to drain a flooded basement where a pipe has burst in a home, or could also be used for the transmission of fluids in an industrial setting, particularly where these fluids are unsafe to handle (they may be made up of corrosive chemicals), or contain solids and fibres within them that also need to be removed.

Where these types of applications are a necessity, there is also a need for an effective and efficient pumping solution to ensure that it happens properly.

Enter vertical spindle sump pumps, the ideal solution to meet these needs in just about any setting. They take a fresh approach to drainage, dewatering and moving clear or even contaminated fluids from one place to another.

Bu what exactly are they, what are they used for, what are the benefits to using them yourself, and where should you look if you would like to find one to buy.

We will answer these questions and more; right here.

What are Vertical Spindle Sump Pumps?

Vertical spindle sump pumps are designed to be partially submersible in the fluid that it is supposed to pump.

To do this without causing any damage to the pumps itself, they are designed with their electrical components at the top of the pumping shaft where it will be safely removed from any liquids that could cause harm to them.

At the bottom of the shaft, a pump can be safely submerged in the fluid to effectively pump it out.

They can be made from varying materials, though are popularly made from stainless steel alloys that are resistant to chemicals and corrosion.

The reason for this is that they are often used to transfer corrosive chemicals which can be dangerous to handle and would quickly compromise the structural integrity of the pump when it is used.

They may also come with various accessories and specifications that are determined according to the requirements of whoever is using it, making for an endless variety depending on your needs.

Related Types of Pumps

While vertical spindle sump pumps are ideal for their specific applications of drainage, there are a few other pumps out there that fulfil similar purposes, albeit in different ways, while being suited to different types of environments and setups.

These related types of pumps are centrifugal pumps, well pumps, water pumps and dewatering pumps, respectively.

Let’s take a bit of a closer look at each:

Centrifugal Pumps

Also used to transfer fluids, centrifugal pumps use rotational kinetic energy and converts it to hydrodynamic energy to create the flow.

They are generally powered by electric of fuel-motor and are suited to fairly large-scale pumping activities, such as facilitating fluid control in piping systems inside of industrial plants.

They are quite bulky and are permanently fitted to wherever they are installed. This and the method of pumping that they use set them apart from vertical spindle sump pumps.

Well Pumps

As the name suggests, these types of pumps are typically used to pump water upward from a well or borehole to provide water to houses, buildings or piping systems with relative ease and even distribution.

Water well pumps themselves come in a number of different types, ranges and sizes depending on how they are intended to be used.

They are also submersible, just like sump pumps, since they are generally placed in the water deposits they are expected to pump.

Water Pumps

Water pumps use a simple electric motor to direct the flow of water through mechanical action.

It should be noted that one of their characterising features is that they are limited in fluid types, to simply pumping water.

They are not, as such, well suited to pumping chemicals, sump or any other potentially damaging fluids, but are far better suited to applications such as irrigation and water extraction.

Dewatering Pumps

Dewatering pumps are a type of centrifugal pump. They are generally installed in buildings that are situated below ground level, and as such, may face the challenge of high groundwater levels.

Their applications are fairly diverse, ranging from being used in any place such as mines and factories that may face a real challenge with collections of water that need to be removed from an inside area.

They are large, heavy and generally installed in a fixed fashion to wherever they are needed.

They are also made from a submersible pump which is placed in a place where water is expected to rise above an unwanted level.

Each of these pumps operates in a similar fashion to vertical spindle sump pumps, albeit for different scales and activities.

Though often not being able to be used interchangeably, especially where the fixed nature of certain pumps makes them a permanent feature of where they are being used, vertical sump pumps do offer a bit more versatility than the others.

The Benefits of Vertical Spindle Sump Pumps

On top of that, vertical spindle sump pumps also offer a range of unique advantages and benefits when applied to the correct applications; particularly in industrial environments where the challenges faced by plants require fairly specialised solutions.

Let’s outline a few of their top benefits here:

Lowered Carbon Footprint

Vertical spindle sump pumps work with remarkable efficiency characterised by low power costs and fuel consumption. This makes them an excellent choice for those who want to do their bit to lower carbon emissions to protect the global environment.

This also means that these pumps come with reduced operational costs, resulting in long-term financial savings over time, for your business.

These savings are further enhanced through a reduced need for maintenance, making Vertical spindle sump pumps an incredibly cost-effective option all round.

Reduced Operational Noise

For the most part, Vertical spindle sump pumps operate without much noise, which is great for working environments that use them consistently, or even when they need to be used in a home without disturbing the peace.

The added advantage of this is that the sound made by the pump can be used as an indication of its condition.

For instance, if your (usually noiseless) pump starts to make a scene each time you use it, it could be a sign that it needs to undergo maintenance.

A Portable Pumping Solution

One of the top advantages to Vertical spindle sump pumps in comparison to other types is that they are portable.

Unlike larger solutions which are always installed in a fixed position (and are also far too bulky to move around easily), these pumps can be moved around to wherever they need to be used with relative ease and without taking up much time.

Ease of Installation

Because they are lightweight and fairly simple to place, Vertical spindle sump pumps can be installed to all kinds of environments.

Often these environments need to be able to accommodate the pump through a pre-dug trench that allows the water to be easily channelled to the submerged pump.

A Versatile Set of Applications

Vertical spindle sump pumps have a number of specialised applications when compared to other types on the market.

Their primary function is to pump clear or contaminated fluids, slurries and liquids that contain large solids.

On top of this, they are often used for pumping water out of flooded areas.

This is particularly useful where water tables are situated above the foundations of a structure; whether that be a building or a home, and there is a high chance of damp setting in.

Finding the Right Vertical Spindle Sump Pump Supplier

Now that you have gone through all of the different types of pumps out there, as well as the top benefits of using vertical spindle sump pumps, the next big question is: where can you find one that is reliable and cost-effective.

Selecting the right supplier for these types of pumps is as important as selecting the right type for your needs.

There are plenty of suppliers out there, and not all of them are made equal. They offer services and products in varying degrees, which makes it essential for you to find the right one when sourcing vertical spindle sump pumps.

To help you make the best possible choice in this regard, we have chartered up a few simple questions to ask yourself when dealing with suppliers, to make sure that you get the quality and service that you need from them, to make the most of your purchase.

These questions are fairly simple, but may not come with simple answers, so it is important to consider them carefully before making any purchases.

They include questions about the company’s experience, their pricing, the variety of pumps they have on offer, as well as the availability and quality of their after-sales services and support:

 Check their Experience

The first thing you want to take stock of when dealing with industrial pump manufacturers is their experience in the industry.

How long have they been in operation as a company? This will determine how effective their business runs as a whole, how closely they can come to satisfying their customers, and how much experience they have with providing after-market support if they do at all.

You also want to take stock of their accumulative experience, which is the total of the experience held by the representatives of the business. A vast accumulation of total experience generally puts the entire business in a better position to satisfy their clients.

How is their Pricing?

This one may seem like an obvious point, but it is all-too-often overlooked, especially by those who are not particularly familiar with the industry.

Finding the right price is a bit of a balancing act, and in any balancing act, you don’t want to lead too much to either one side or the other.

A low cost might be an attractive point to the supplier you are considering, but you have to wonder what kind of effect that will have on the quality of their products and services. Often suppliers will lower their prices where they know that their offers are lacklustre, in order to make them seem more appealing.

On the other hand, a high price isn’t always a representation of high quality, but could just mean that the supplier is opening up their profit margins as widely as possible.

To this extent, it is good to find a supplier that does offer competitive prices for their offers, without them being suspiciously low or high.

The Availability and Variety they Offer

Even if the company you are looking at has the exact vertical spindle sump pump you are looking for, it is still a good idea to take a look at what else they have in stock. You want to look for signs of variety, and of course quality.

If they have a massive selection, they are likely very well established, which generally equates to a more reliable service.

It will also mean that they likely have all the replacement parts and maintenance services you may need to keep your vertical spindle sump pumps running in the long-term.

After-Sales Support and Services

With any industrial equipment, the provision of after-sales support and services are essential. Because of this, you need to ensure that the supplier you are looking at, is able to provide these much-needed services which will account for repairs, replacements, maintenance and even training for proper use.

4 Types of Chemical Pumps

It is true that most chemical pumps can be used for almost any application in the chemical industry, but in some cases pumps need to work under rigorous conditions (think of liquids containing solids or other materials that makes them difficult to pump. In these cases, it is better to know what options are available – or, if you’re still unsure, chat to any of the sales professionals at Chemical Pump and Valve Marketing!

  1. Centrifugal pumps
    The most common pump type, these are simple pumps which are generally the most budget-friendly. Centrifugal pumps draw liquid, through suction, into an impeller which leads to a vacuum. One disadvantage of this pump, is the potential for poor suction power if it is not primed correctly.
  2. Turbine pumps
    With turbine-like impellers, these pumps move liquid with radially oriented teeth. Turbine pumps have the versatility of centrifugal pumps with higher discharge pressures (that of positive displacement pumps) – but these should not be used to pump liquids with solid content.
  3. Positive displacement pumps
    Rotary pumps which may include gear, screw, rotary vane and piston pumps, to name a few. Positive displacement pumps are more efficient than centrifugal pumps when it comes to moving high viscosity fluids, and can also pump at high pressure. In addition to this, these pumps are also capable of moving low vapor pressure fluids, which flow at low speeds while creating more resistance for the pump.
  4. Diaphragm pumps
    A type of positive displacement pump, diaphragm pumps move liquids and liquid-gas mixtures through a reciprocating diaphragm. These pumps have no internal wear components and require no sealing or lubrication, which means they require less maintenance than other pump types, while eliminating the risk of oil vapour leakage and fluid contamination.

Horizontal Centrifugal Chem-Pumps VS Vertical Submersible Chem-Pumps

How do you choose between a horizontal and vertical chemical pump?
Of course, the primary difference is the shafts’ shape and position. The deciding factor might in face, just come down to convenience, as the rest of these pumps’ attributes are quite similar.

Horizontal Centrifugal Chemical Pumps:

These are designed to transfer or drain fluid with faster flow rates, by way of a direct drive motor. Horizontal centrifugal chemical pumps are high performance, and offer agile, uninterrupted fluid flow. They are also airtight and environmentally safe. Chemical Pump & Valve Marketing offers Horizontal Centrifugal Chemical Pumps® Monoblock design or coupled units with capacities up to 440 cbm/hour, heads up to 60 meters, can withstand temperatures up to 120° and features baseplates made of corrosion resistant epoxy resin.

Some advantages to consider, include the ease of installation and maintenance of the horizontal pump due to accessibility. It can also be used in most indoor applications, as it does not need a lot of headroom and can be connected to an electric motor, engine or turbine directly.

Vertical Submersible Chemical Pumps:
With a wide range of applications – from automatic drainage to heat transfer or chemically aggressive fluids, vertical submersible chemical pumps have a few advantages over their horizontal counterparts. They use up to 75% less floor space, has a steeper head capacity curve and the driver is not on the floor, so there is less danger of damage caused by flooding. So where there is limited ground space, this could be a suitable option. Our Vertical Submersible Chemical Pumps® with Cantilever design, no submersed bearing, bushes, or seals can run dry continuously and as with the Horizontal counterpart, has a capacity of 440 cbm/hour, heads up to 60 meters, can withstand temperatures up to 120°.

Our chemical pumps are used in nearly all major South African chemical industries and in many platinum, gold and uranium mines, where a harsh, corrosive environment is present, and downtime costs must be kept to a minimum.

How Do Centrifugal Pumps Work?

Pumps move liquids or gasses from one point to another. A pump is made up of an inlet, a casing and an outlet, liquid enters the inlet into the casing and is discharged through the outlet of the pump. The inside of the pump contains a component that moves the liquid through the pump increasing the pressure and flow.

What Makes a Pump a Centrifugal Pump?

For a pump to be classified as a centrifugal pump however it needs to have two specific components, an impeller and a volute casing. An impeller is a rotating a disc with vein like curves on the surface. The volute casing houses the impeller and the fluid that is being pumped.

When the fluid enters the pump, it causes friction between the impeller causing it to start rotating, thus propelling the fluid out towards the outlet.

The impellers speed and size and the viscosity of the fluid all impact the pressure and flow that the liquid will be discharged at.

Properly Priming a Pump

The pump’s impeller must always be fully submerged in liquid, the impeller can’t pump air, so it is important to flood the volute casing with liquid before the pump is switched on, this process is called priming.

It is best to place the pump below the source of the tank holding the fluid, this avoids the pump being starved of fluid resulting in cavitation.

The Casing

The casing of the centrifugal pump is called a volute casing because of its spiral shape. The discharge outlet and the volute chamber are separated by the cutwater which purpose is to ensure that the liquid leaves the pump.

The size of the volute chamber dictates the flow of the liquid, the bigger the chamber the slower the flow will be, this follows the Bernoulli’s Principle, the slower the flow of the liquid the higher the pressure will be and the faster the flow the lower the pressure. The pressure allows the liquid to move achieving the desired outcome of the pump.

Safely Transport, Store and Dispose of Chemical Materials

Chemical pumps and valves, including acid pumps have been tailored to carry corrosive and biochemical materials such as sulphuric acid, hydrochloric acid and other abrasive liquids safely from one point of manufacture to the next. Without sufficient pumps and valves things can go horribly wrong, particularly in any of the industries discussed below.

The Fertiliser Industry

Whilst consumers of the finished product see something that promotes the growth and vitality of their gardens, the reality is that fertiliser is a compound comprised of various chemicals – many of which can be harmful to those who work with them if the necessary precautions are not taken.

Sulphuric acid is only one of the highly corrosive chemicals used in the manufacture of fertiliser, and its transportation between manufacturing points needs to be carefully monitored, having taken all of the necessary precautions.

Pool Chemical Industry

Again, consumers use the product and see a wonderfully clear and blue pool as the result, but the manufacturing of various pool maintenance chemicals and chlorine is dangerous and incorporates many hazardous materials. These hazardous materials need to be stored, used and disposed of safely and effectively; chemical pumps and valves make the entire process possible as well as safe.

Risks of Insufficient Pumps

Having insufficient pumps to transport acids, solvents, alkalies etc. puts the industry and location in question at risk of chemical spills. These chemical spills have the potential to damage equipment, cause toxicity and burns to the human body (including the lungs) and react with one another to create explosions and toxic environment. Damage to equipment can cost a business millions whilst human lives are priceless.

Looking for Chemical Pumps, Acid Pumps and Associated Valves?

If you are in an industry that works with biochemical, acidic, alkaline or any other abrasive liquid, then you should be. Chemical pumps and valves can help your business to successfully, safely and efficiently store, transport and dispose of hazardous material.

Why Epoxy Resin is the Perfect Material for Chemical Pumps

Chemical pumps come in a range of types that are typically defined by their functions, capacity and the types of materials they are made from. One such type of material that stands out against most others, is epoxy; the resin of which is often used as the primary material in chemical pumps in South Africa, since they’re cost effective and meet the demands of the South African climate quite well.

Epoxy resin, as a material for chemical and acid pumps, comes with a great number of advantages. All of which make it ideal for the applications of the chemical processing industry.

Resistance to Thermal Stress

Epoxy resin is remarkably resistant to high temperatures, the kinds that are often found in industrial applications. In the presence of extreme heat, epoxy resin will retain its structure and durability, making it a reliable material when used under extreme conditions.

Resistance to Degradation

Epoxy resin is also very resistant to gradual degradation, which is a fancy way of saying that it will last longer than most other materials. Since you need your plant’s chemical pumps to be consistent and reliable, epoxy is ideal for maintaining a reliable chemical pump.

Resistance to Corrosion

The main reason why epoxy resin is used for chemical pumps, is that it is one of the few materials out there that is completely resistant to corrosion from solvents, acids, alkalis and salts. All of these can worth through other materials, quickly or gradually, essentially undermining their integrity and effectiveness.
