Welcome to the home of SAIP-USA, your United States and Mexico source for information regarding pulsation dampeners and hydropneumatic accumulators from SAIP srl of Milan Italy. SAIP pulsation dampers and accumulators can be found in a number of industrial sectors including: Petrochemicals, pharmaceutical, and food and beverage. SAIP Pulsation Dampeners and Accumulators are on the preferred vendors list of many of the world's top pump users and manufacturers. The Hydropneumatic Accumulators and Pulsation Dampers from SAIP can be used in a variety of technical applications; the most important are: Storing energy: The accumulator is used in cases where the pump circuits need a big flow of oil in a short period. Standby energy storage: The accumulator can deliver energy when a pump circuit is loosing flow and pressure, due to a black-out of the pump(s). Compensation for volume variations: When temperatures change, volume also changes due to dilatation of the fluid, the pulsation damper will compensate the volume preventing pressure increases in the pump circuit. Water hammer dampening: The pulsation damper will absorb the pressure increase due to the waterhammer caused by the quick closing of valves. Leakage make-up: The accumulator must keep the pressure constant for applications which require static pressure for long periods. Shock absorption: Mechanical shocks are absorbed by the pulsation dampener Pulsation dampening and noise dampening: Pulsation dampeners can be used in pump circuits where it is necessary to dampen pressure oscillations caused by dosing pumps and, as a consequence, damping the noise caused by the pulsations.
