Understanding positive displacement pumps | PumpScout

A more common type of diaphragm pump is the air-operated double diaphragm pump. It uses pressurized air to activate the diaphragms instead of a mechanical device. This is basically two pumps in one -- one is on the suction cycle, while the other is on the discharge cycle. ...<< more>>

How Do Air Operated Double Diaphragm Pumps Work?

An AODD pump is a type of positive displacement pump that uses compressed air as a power source. The compressed air is shifted from one chamber to the other by a linked shaft that allows the chambers to move simultaneously. ...<< more>>

Positive Displacement Pump Types-Diaphragm

A diaphragm pump (also known as a Membrane pump, Air Operated Double Diaphragm Pump (AODD) or Pneumatic Diaphragm Pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves either side of the diaphragm (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid. ...<< more>>

Diaphragm pump - Wikipedia

A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid. ...<< more>>

A Specific and Detailed Guide How Diaphragm Pumps Work

A diaphragm pump is a positive displacement pump which utilises two flexible diaphragms that reciprocate back and forth, creating a temporary chamber. The flexible diaphragms both draw in and expels fluid through the pump. ...<< more>>

Positive displacement pumps - petrowiki

Positive displacement pumps were developed long before centrifugal pumps. Liquid is positively displaced from a fixed-volume container. Positive-displacement pumps are capable of developing high pressures while operating at low suction pressures. ...<< more>>

The Differences Between Centrifugal Pumps Vs. Positive

Positive displacement pumps draw fluid into a compartment at the inlet and move it to an outlet for discharge, most typically using a rotary, reciprocating, or diaphragm method to move fluid. The main difference between these types of pumps and centrifugal is that positive displacement pumps will move fluid at the same speed regardless of the ...<< more>>
