The type of pump you'll need will depend on your application, including: The type of liquid you wish to pump The distance you wish to move the liquid The volume you need to achieve over a specific time frame But it can be difficult to know exactly which pump you should choose.
Centrifugal Pumps This type of pump is one of the most common in use today. For this reason an axial flow pump is by definition not "centrifugal" in its pumping action. Mixed Flow: The mixed flow impeller discharges fluid in a conical direction using a combined radial and axial pumping action — as suggest by the title. Figure 1 illustrates these clasification. Positive Displacement Pumps This type of pump creates an expanding cavity on the suction side of the pump and a contracting cavity on the discharge outlet.
Positive displacement pumps come in two designs: Reciprocating: In this design, the suction is created by a piston which plunges into and pulls out of the material. Valves are used to ensure that the flow only moves in one direction. A reciprocating design therefore pulses the liquid at identical intervals Rotary : A rotary design uses two gears which mesh together.
The movement of the gears creates high pressure on the discharge side which creates flow Due to the design, positive displacement pumps are better at handling viscous material. There are many different types of positive displacement pumps, such as: Rotary lobe pump Progressing cavity pump Rotary gear pump Piston pump Diaphragm pump Screw pump Gear pump Vane pump Peristaltic hose Global Pumps supply a huge range of industrial pumps, stocked locally in Australia, with fast delivery.
