Surge Suppressors

Suppress hydraulic surge (water hammer) created by closing valves, back surge and pump start-up and stop.

A Pulsation Dampener placed at the pump's discharge will produce a near steady fluid flow up to 99% pulsation and vibration free.

  • Protects pipes, valves, fittings, meters, and in-line instrumentation from destructive pulsations surges, cavitation, thermal expansion, and water hammer.
  • Creates steady and continuous flow when dosing, blending or proportioning additives.
  • Ensures accuracy, longevity, and repeatability of in-line meters.
  • Enables uniform application of material in spraying and coating systems.
  • Reduces product agitation, foaming, splashing and degradation of product.
  • Provides liquid energy storage for emergency valve closure and other equipment shutdown.
  • Reduces overall energy cost with continuous flow, rather than start/ stop flow.
  • Operates as a reservoir for make-up fluid.
  • Simple, reliable design and quick installation.
  • Easy in-line maintenance.
  • Pressure ranges up to 10,000 psi (689.4 bar) available from stock.
  • Temperature ranges from -60°F to +400°F (-51°C to +205°C) available from stock
  • Custom models, larger sizes and higher pressure ratings available on request. Contact Blacoh for more information.
  • Bodies available in a full range of chemically resistant materials.
  • Bladders available for even the most corrosive applications.

Models in stock for all positive displacement pumps with discharge sizes from 1/8"  to 6".
