Blacoh Pulsation Dampeners & Surge Suppressors
Blacoh Pulsation Dampeners & Surge Suppressors

Positive Displacement (PD) pumps create pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging the entire pumping system.
BLACOH Pulsation Dampeners & Surge Suppressors remove virtually all hydraulic shock, enhancing all-around performance and reliability of fluid flow in industrial and chemical transfer applications.

SENTRY BENEFITS:

  • Whether a piston, plunger, air diaphragm, peristaltic, gear, or diaphragm metering pump, a SENTRY 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

SENTRY FEATURES:

  • Pressure ranges up to 10,000 psi (689.4 bar) available from stock
  • Easy in-line maintenance
  • Simple, reliable design and quick installation
  • Models in stock for all positive displacement pumps with discharge sizes from 1/8″ (3.18mm) to 6″ (152.4mm)
  • 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.
  • Bladders available for even the most corrosive applications
  • Bodies available in a full range of chemically resistant materials

Blacoh Hybrid Combination Back Pressure valve & Dampener

Location and proximity are key when installing pulsation dampeners and back pressure valves in any pumping system. A back pressure valve installed in series with a dampener can negate the dampening effect if the valve is opening and closing before the dampener is able to capture a full pulse. This quick-opening effect can also create too much gain within the back pressure valve resulting in inefficiency and chatter.

By combining the dampener and back pressure valve into a single engineered unit, we’ve eliminated the most common issues with installation for a more efficient, simplified system.
