Delivering large amounts of material at low pressures is a great use for diaphragm pumps. As they don't have a piston moving through a cylinder but rather a straightforward rubber diaphragm or diaphragms that are shifted side to side to allow material to be conveyed, they often resist wearing (more on diaphragm vs piston pumps can be found here). After deciding that a diaphragm pump is the best option for your pumping requirements, it is now time to discover how to choose a diaphragm pump.

Knowing exactly what you need to pump is the first step in choosing a diaphragm pump. The pump provider will be able to help you with the proper material the pump needs if you are clear about what you are pumping. Long service life is the objective. The wrong material will be chosen, which could lead to costly repairs, downtime, and even safety concerns for the operator.

THE TEMPERATURE AT THE PUMP

For the pump casing, seals, and diaphragms, the fluid's pumping temperature is also crucial. Poor material selection may be caused by an erroneous pumping temperature specification. Poor material that is inappropriate for the fluid temperatures might cause premature pump failures with possibly harmful effects.

VISCOSITY

The simplest approach to understand viscosity is to think about how fluids flow.

SWEEP RATE What amount of fluid must be transferred? And how quickly? For instance, it can take two minutes to decant a 200-liter drum of fluid into a process reactor.

Operational Stress There are a few fundamental factors to take into account when deciding how the pump will be built or used. Where will the pump get its fluid, for instance? Will a tank's base support the pump's position? The fluid will flood the pump and prime it as soon as the tank valve is opened in this design, where the pump is piped directly from the bottom of the tank. This is referred to as "flooded suction." On the other side, the pump might be positioned higher than the fluid. The suction hose or pipe will descend below the pump and into a sump or basement in this situation if the pump is standing on a floor.
