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!
- 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.
- 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.
- 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.
- 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.
We offer a full range of CHEM-PUMPS®, available in the following materials: epoxy resin, High Density Polyethylene, Polypropylene, 316 stainless steel and non-corrosive alloys. We have also developed a chemical self-priming/self-venting pump unit! Our pumps are also able to seamlessly pump flows of up to 450 cubic metres per hour and pressure heads of 60 metres.
