in Diaphragm Pumps

Why select a pneumatic diaphragm pump?

Run Dry Without Damage
Diaphragm pumps are selected when the user needs a pump that is capable of running dry, or in other words, when there is a possibility that the pump may not be monitored and the fluid being pumped could be depleted. The diaphragm pump will simply go into a snore mode. Any rotating type pump, a centrifugal for example, if left without fluid passing through the unit, would result in a damaged mechanical seal with potentially costly downtime, spares, and danger to personnel and environment.
Safe Chemical and Flammable Fluid Transfer
Air Operated Diaphragm Pumps are also selected when there is a need to transfer Toxic, Acidic or Alkaline Chemicals or Slurries. The sealless diaphragm pump design enables one to safely and simply handle difficult fluids.
Flammable environments or applications where the pump system is required to transfer flammable fluids, makes the intrinsically safe air operated diaphragm pump a unique and preferred technology. Without the need for expensive electrical installations and specialized staff, the air operated diaphragm pump with ATEX certification is a great option for both bulk and process pumping applications.
Simple Pump Automation
Pneumatic Diaphragm Pumps are ideal for selection when there is a demand for simple, safe, low-cost plant automation. Close a valve on the discharge pipe and the pump will simply stop, open the valve and the pump will continue to transfer fluid. One can alternatively simply shut the pneumatic feed to the air motor of the pump and the pump will stop, open the valve and the pump will continue to operate. This is one of the simplest types of pumps to automate and integrate into a process.
Unskilled Operators
Air Driven Diaphragm Pumps are also extremely popular where the process is to be operated by unskilled or semi-skilled labour. The safety aspect of both staff, equipment, process, and environment is a key factor in selecting this type of pump technology. Because the pump is seal-less, it will not leak even when it runs out of fluid to pump or when an operator closes the discharge valve in error. Mine or construction site dewatering applications are prime examples for this type of pump abuse. Diaphragm pumps allow for circumstances in the fluid transfer space where other types of pump technologies will struggle to operate effectively.
