Blacoh dampener pumps are designed to regulate and stabilize fluid flow in various industrial applications. These pumps feature pulsation dampeners that absorb pressure fluctuations and eliminate pulsating flow. By smoothing out the flow, Blacoh dampener pumps enhance system performance, reduce wear and tear on equipment, and ensure consistent fluid delivery. They are commonly used in industries such as chemical processing, oil and gas, water treatment, and food and beverage production to maintain steady flow rates and minimize vibration.

How the Pulsation Dampeners & Surge Suppressors Work

Pulsation dampeners absorb pressure spikes' energy by collecting and subsequently releasing process fluid during the pump's suction stroke. By maintaining fluid movement, these dampeners mitigate vibration and the fluctuating, irregular flow resulting from pulsation.

How the Sanitary Pulsation Dampeners Work

The Sanitary Pulsation Dampeners elevate system efficiency and dependability by effectively eradicating nearly all pulsation and vibration. They generate a seamless laminar fluid flow, thereby averting product agitation, splashing, and foaming. Moreover, they serve as a shock absorber, shielding systems and instrumentation against harmful pressure surges.

  • Inlet Stabilizers


  • The J Model air control can be adjusted for positive inlet pressure or negative inlet pressure (suction lift)
  • Offered in a variety of metal and plastic materials in sizes from 10 cu in (.16L) up to 10 gallon (37.85L)
  • ATEX and CRN certification on metal models
  • NSF/ANSI certification on select plastic models

How the Inlet Stabilizers Work

The Inlet Stabilizer functions as an accumulator, storing fluid and dispensing it back into the line as required. It effectively eradicates almost all acceleration head loss by enabling the pump to draw fluid from the dampener instead of the pipeline, thus mitigating the risk of cavitation and guaranteeing complete chamber fill with each inlet stroke of the pump.
