blacoh pulsation dampening

BLACOH is the industry standard for dampening the pulsation created by positive displacement pumps. They have been in business for more than 30 years, providing smooth fluid flows for pumping systems all over the world. BLACOH stands alone as the industry leader and foremost expert in the manufacture of fluid control products for all facets of municipal and industrial process industries, and virtually every application, from the harshest chemicals to the most delicate cosmetics.

Pulsation Dampeners for AOD Pumps

SENTRY Pulsation Dampeners, Surge Suppressors and Inlet Stabilizers remove hydraulic shock and vibration, enhancing all-around performance and reliability of fluid flow applications. All SENTRY dampeners manufactured by BLACOH use pressure bodies made in the USA to ensure quality. Prior to shipment, each and every dampener is factory tested at design pressure or higher to assure proper function and leak-free operation.

All Pumps has been importing, servicing and supplying BLACOH Products in Australia for 15 years and support the full BLACOH range of pumps and spare parts.

Blacoh Sentry Pulsation Dampeners

Remove up to 99% of System Shock

Positive displacement pumps create destructive pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging piping and system components. SENTRY Pulsation Dampeners and Surge Suppressors remove virtually all system shock, enhancing the performance and reliability of fluid flow in municipal, industrial, sanitary and chemical transfer applications.

Pulsation Dampeners for Metering Pumps
  • Protect pumps, piping, valves, fittings, meters and in-line instrumentation from damaging pulsations, cavitation, thermal expansion, hydraulic shock and water hammer.
  • Prevent destructive pressure surges caused by pump startup and shutdown.
  • Prevent hydraulic shock resulting from emergency valve closure and other equipment shutdown.
  • Prevent agitation, foaming, splashing and degradation of product.
  • Ensure accuracy, longevity and repeatability of flow meters and pressure gauges.
  • Ensure a smooth steady flow in metering and chemical injection processes.
  • Ensure uniform and continuous application in spraying and coating processes.
  • Ensure proper measurement, flow and filling applications of food and pharmaceutical products.
  • Ensure consistent flow when dosing, blending or proportioning process additives.
  • Ensure a smooth transfer of viscous or abrasive fluids.

Protect Inlet System Components

Positive displacement pumps contain an inlet valve that alternately opens and closes, creating an acceleration and deceleration of fluid into the pump.

SENTRY Inlet Stabilizers minimise these pressure fluctuations and acceleration head losses by preventing fluid column separation at the pump's inlet. The patented ā€œJā€ Model air control allows for pressure or vacuum settings and is adjustable for suction lift or positive inlet pump conditions. (US Patent 6,089,837)

  • Protect pumps, valves, diaphragms and pistons from excess stress and strain.
  • Protect inlet system components from vibration and fatigue.
  • Prevent premature system component failure and cavitation.
  • Prevent gauge damage due to vibration.
  • Ensure steady inlet flow conditions to extend pump diaphragm life. Ensure complete chamber fill to maximise component service life I Ensure accuracy of inlet side gauges.

  • Temperature ranges from-60oFto+400oF ( -51oCto+204oC). Pressure ranges up to 4000psi (276bar) ā€“ Custom models available up to 100 gallons (378.5L) and 25,000 psi (1,724 bar).
  • Sanitary and flow-through models available for biotech, pharmaceutical and food industries.

Protect and Isolate System Instrumentation

Without proper protection, process fluids regularly contaminate and damage in-line instrumentation. The strength and durability of SENTINEL Diaphragm Seals protect and isolate all forms of system instrumentation from the hazards of corrosive process fluids.

  • Protect gauges and other pressure instrumentation from process fluid contamination and corrosion.
  • Prevent erratic pressure surges and clogging due to solids in process fluids.
  • Protect gauges from freezing and slurries.
  • Ensure gauge and switch accuracy.
  • Ensure accurate and consistent readings with corrosive or solids-laden fluids.

SENTINEL Diaphragm Seals are easily installed, come in a variety of chemically resistant materials, and work in both pressure and vacuum conditions.

  • Reduce costs by replacing expensive gauges with low-cost utility gauges. Diaphragms and seal bodies unconditionally guaranteed.
  • Accuracy of +2% or better full deflection.
  • Pressure ranges to 1000 psi (68.95 bar).
  • 1/4" to 3/4" (6.35 up to 19.05 mm) inlet ports.

Protect Against Pressure Damage, Prevent Siphoning and Ensure Stable Dosage Rates

SENTINEL diaphragm pressure relief valves are designed to continuously regulate fluid flow to protect pumping systems from over- pressure damage caused by defective equipment or a blockage in the pump system line.

SENTINEL diaphragm back pressure valves enhance system performance by applying a continuous back pressure to the system pump. Eliminating fluctuations in downstream pressure prevents siphoning and eliminates varying dosage rates, and the continuous back pressure ensures proper check valve operation in metering pumps when system pressure is too low.

  • Robust machined construction.
  • Compact size for OEM applications.
  • Adjustable 10 to 250 psi (0.69 to 17.24 bar) I Optional 350 psi (24.13 bar) rated valve.
  • 3 Port, 2 Port and 90o configuration.
  • Vulcanised PTFE/EPDM diaphragms

Prevent Costly and Hazardous Spills When Pump Diaphragms Fail

Diaphragm failure in air operated diaphragm pumps allows process fluid to escape through the pump's air exhaust port. Unmonitored, the spill can result in significant expense to your company due to lost product, hazardous material cleanup, EPA reporting and system downtime.

SPILLSTOP's patented design prevents hazardous and costly spills by capturing the expelled process fluid and automatically shutting down the pump. (US Patent 5,501,577)

  • Fully pneumatic operation eliminates the need for dangerous electronics or unreliable batteries.
  • Warning alarm and automatic backup pump switchover. Compatible with all AODD pumps with discharge sizes from 1/4" (6.35 mm) to 4" (101.6 mm).
