5 Elements to Consider during Pump Selection

09 February 2022

Pumps are generally devices that can transport fluids or slurries through mechanical action so they can convert electrical energy into hydraulic energy. Depending on the needs of industries, they can likewise be maximised in moving chemicals, oil, petroleum, and food.

There are different types of pumps that can be maximised by industries. Two basic types of pumps that are available today are dynamic and positive displacement pumps. Dynamic pumps can be further classified into centrifugal, vertical centrifugal, horizontal centrifugal, submersible, and fire hydrant systems. Positive displacement pumps, alternatively, can be grouped further into the diaphragm, gear, lobe, peristaltic, and piston pumps.

When choosing the best pumps for your applications, here are some elements you need to consider.

  1. Liquid Type

One of the elements that you must consider during pump selection is the type of liquid you will be processing or maximising. Your liquid may possess specific properties that can be used to pinpoint the type of pump that works best with it. Some properties of your liquid that you can check are the liquid viscosity, operating temperature, vapour pressure, specific gravity, shear sensitivity, presence and concentration of solids, and abrasiveness.

  1. Materials

Another element to consider during pump selection is the material composition of the pump. Knowing the properties of your liquid can already provide you with some idea of the type of materials that are compatible with it. Using pumps that are not compatible with your liquid may only end up ruining your operation as the liquid might damage the pump once it comes into contact. Studying the chemical compatibility charts can help you identify the appropriate pump materials for your liquid or substance.

  1. Significance

There are specific applications wherein pumps must work for very long hours. If your application needs a pump that can process liquids without any downtime, then you must opt for one that is made from heavy-duty materials and components. Take note, however, that these pumps can be expensive as they are justified by the longevity of their materials and overall composition. If your pumps, alternatively, can be serviced in the middle of the operations, then you can go for cheaper options.

  1. Environment

Aside from their significance, you must also consider the working environment of your pumps in choosing one. Outdoor environments would normally be bombarded with damaging weather elements. Hence, you must opt for pumps that can withstand them effectively if you are planning on using them outdoors. Processes in environments that may have violent vapours or dust, on the other hand, may require pumps that maximise special motor features.

  1. Flow Rate and Pressure

Two more elements to consider when selecting the best pump for your application are flow rate and pressure. The needed flow rate of your pump will depend on the total volume of the liquid and the time it requires to be moved. Pressure, alternatively, can be measured by knowing the pipe size, static lifts, and friction losses of the system equipment such as filters and valves.
