How the Pump Works

LEFT STROKE

The air valve directs pressurized air to the back side of diaphragm A. The compressed air is applied directly to the liquid column separated by elastomeric diaphragms. The diaphragm acts as a separation membrane between the compressed air and liquid, balancing the load and removing mechanical stress from the diaphragm. The compressed air moves the diaphragm away from the center block of the pump. The opposite diaphragm is pulled in by the shaft connected to the pressurized diaphragm. Diaphragm B is on its suction stroke; air behind the diaphragm has been forced out to the atmosphere through the exhaust port of the pump.
The movement of diaphragm B toward the center block of the pump creates a vacuum within chamber B. Atmospheric pressure forces fluid into the inlet manifold forcing the inlet valve ball off its seat. Liquid is free to move past the inlet valve ball and fill the liquid chamber (see shaded area).

Mid stroke

When the pressurised diaphragm, diaphragm A, reaches the limit of its discharge stroke, the air valve redirects pressurised air to the back side of diaphragm B. The pressurised air forces diaphragm B away from the center block while pulling diaphragm A to the center block.
Diaphragm B is now on its discharge stroke. Diaphragm B forces the inlet valve ball onto its seat due to the hydraulic forces developed in the liquid chamber and manifold of the pump. These same hydraulic forces lift the discharge valve ball off its seat, while the opposite discharge valve ball is forced onto its seat, forcing fluid to flow through the pump discharge. The movement of diaphragm A toward the center block of the pump creates a vacuum within liquid chamber A. Atmospheric pressure forces fluid into the inlet manifold of the pump. The inlet valve ball is forced off its seat allowing the fluid being pumped to fill the liquid chamber.

Right stroke

At completion of the stroke, the air valve again redirects air to the back side of diaphragm A, which starts diaphragm B on its exhaust stroke. As the pump reaches its original starting point, each diaphragm has gone through one exhaust and one discharge stroke. This constitutes one complete pumping cycle. The pump may take several cycles to completely prime depending on the conditions of the application.

Working of Peristaltic Pumps

As fluid enters the head of a peristaltic pump, it becomes trapped between two rollers. This “pillow” of fluid is followed by a void, where the tubing is occluded by the rollers. Alternating pillows and voids cause fluid flow to be pulsated, rather than smooth and continuous Figure.
If pulsation is undesirable, using a pump head with adjustable occlusion can lessen the pulsation by a quarter. Reducing occlusion decreases the degree of pulsation because there is less distinction between fluid pillows. Some applications, however, are more sensitive to the pulsating flow produced by a peristaltic pump. These applications may require smoothing the flow by more than 25%. In these cases, four other methods may be considered for reducing pulsation further: using pump heads with offset occlusion and multiple-roller design; mounting multiple pump heads at an offset; using a pulse dampener; and changing the configuration of the discharge tubing.
