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).
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.
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.

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.
A pulse dampener can be inserted into the discharge line to reduce pulsation. As the pulsating flow enters the dampener vessel, the air pocket trapped above the fluid absorbs up to 90% of the pulsation. A smoother flow leaves the vessel.
For all tubing sizes, a pulse dampener can easily be fabricated using a retaining vessel and appropriately sized fittings, The outlet of the dampener should be at the same height as, or lower than, the inlet in order to reduce dead volume. Both inlet and outlet should be located near the bottom of the vessel to trap air in the top of the vessel. Changing the configuration of the channel through which the tubing flows can also reduce pulsation. Extending the length of the discharge tubing several times and selecting a softer tubing material, such as silicone, can reduce pulsation by as much as 60%. Softer tubing helps absorb fluid pulsation, and a longer discharge line increases friction. The increase in friction raises back pressure, which compresses the pulses together, thereby reducing pulsation.
