Protect your System Components with Diaphragm Pump Pulsation Suppressors

Sandpiper Tranquilizers are premium pulsation dampeners/diaphragm pump surge suppressors. They are “Universal” (can be used with any pump brand) and easily installed tools for quieter, surge-free flows and steady liquid pressures protecting both pumping fluids and process equipment. We recommend using a tranquilizer with every pump in all applications to extend product life and improve overall performance. 

How A Surge Dampener Works

All air-operated double-diaphragm (AODD) pumps create pulsations of product fluid as they operate. A pulsation dampener uses a flexible diaphragm to separate a liquid chamber from a compressed air chamber. As the product fluid pulse enters the liquid chamber, it displaces the diaphragm upward into the compressed air chamber. The force of the compressed air slows the speed of the diaphragm’s displacement and effectively dampens the fluid pulsation.
