Blacoh™ Pulsation Dampener

Brochure - Pulsation Dampener
Blacho™ Pulsation Dampener
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's SENTRY 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:

* Sizes available for all positive displacement pumps with discharge sizes from 1/8" (3.18mm) to 6" (152.4mm)
* Simple, reliable design and quick installation
* Easy in-line maintenance
* Pressure ranges up to 4000 psi (276 bar) available from stock
* Temperature ranges from -60°F to +400°F (-51°C to +205°C) available from stock
* Custom models available up to 100 gallons (378.5L) and 25,000 psi (1724 bar)
* Bodies available in a full range of chemically resistant materials
* Bladders available for even the most corrosive applications

Blacoh™ Accumulators

Brochure - Accumulators
Blacho™ Accumulators

Accumulators are storage vessels that hold fluid under pressure and are commonly used in fluid power systems to store fluid as energy to be released on demand. When used in hydraulic circuits and machinery, they are sometimes referred to as hydraulic accumulators or hydropneumatic accumulators. Accumulators are also used to eliminate pulsations for a smooth fluid flow and protect systems from hydraulic shock. The most popular design has an internal bladder that acts as a separator between the stored fluid and a compressed gas charge.

BENEFITS:

Accumulators are used in a variety of applications across multiple industries to increase system productivity and lower operating costs.

* Store pressurized fluid as energy
* Temporarily increase/supplement pump flow
* Auxiliary power for equipment cycling, valve closure and emergency shutdown
* Maintain system pressure
* Makeup fluid for system leakage or bleed down
* Compensate for thermal expansion
* Dampen pulsations and vibrations
* Absorb hydraulic shock/water hammer


FEATURES:

BLACOH offers a full line of Accumulators specifically designed for the fluid power market, with single body construction for maximum safety in high pressure applications.

* Bladder, Diaphragm and Piston models
* Bottom and Top Repairable options
* Tested at 1.5 times maximum pressure
* Built to meet ASME standards and most international pressure vessel code requirements

BLACOH Accumulators are available in a variety of sizes and materials suitable for the most demanding applications. *

* Pressure ratings to 5,075 psi (350 bar)
* Sizes from 12 cu in to 13.5 gal (.20 to 51L) – larger sizes upon request
* Carbon Steel and 316L Stainless Steel bodies
* Buna, EPDM, Viton and PTFE bladders
* FNPT, BSP and Flange inlet ports

NOTE: Some Accumulator models offered by BLACOH may be manufactured by North American or European partners. Contact a BLACOH Sales Manager for specific details.

Blacoh™ Inlet Stabilizer

Brochure - Inlet Stabilizer
Inlet Stabilizer

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

The patented "J" Model Inlet Stabilizer works to minimize these pressure fluctuations and acceleration head losses by preventing fluid column separation at the pump's inlet. This improved flow to the pump's inlet effectively extends the service life of all inlet system components.

INLET STABILIZER BENEFITS:

* Ensure complete chamber fill, extending component service life
* Protect pumps, valves, diaphragms, and pistons from excess stress and strain
* Protect inlet components from vibration and fatigue
* Ensures accuracy of inlet side gauges
* Prevent premature system component failure
* Prevent cavitation
* Prevent gauge damage due to vibration
* Extend diaphragm life in all diaphragm pumps


INLET STABILIZER FEATURES:

* Improved inlet flow conditions
* Patented control unit allows you to adjust for pressure or vacuum settings
* Regulates for suction lift or positive inlet pump conditions
* Available in 10 cu in (.16L) to 10 gallon (37.85L) sizes
* All standard models available from stock
* Bodies available in a full range of chemically resistant materials
* U.S. Patent #6,089,837
