Blacoh is a leading manufacturer of fluid control products designed to improve pumping system performance, reliability, safety, and equipment life.
Specializing in pulsation dampeners, surge suppressors, inlet stabilizers, diaphragm seals, and valves, Blacoh helps protect pumps, piping, valves, gauges, and other system components from pressure fluctuations, vibration, water hammer, and damaging system shock.
With solutions engineered for municipal and industrial process applications, Blacoh products are used across a wide range of fluid handling systems where consistent flow, pressure control, and equipment protection are critical.
Company History
Blacoh was founded in 1976 with a focus on solving common issues caused by start-stop, pulsating fluid flow in systems using positive displacement pumps. Since then, the company has grown into a recognized leader in fluid control solutions for municipal, industrial, sanitary, and chemical transfer applications.
For over 45 years, Blacoh has continued to develop engineered products that help improve process system performance, reduce maintenance issues, and protect critical equipment in demanding pumping applications

Product Overview
SENTRY™ Pulsation Dampeners & Surge Suppressors
Blacoh SENTRY™ Pulsation Dampeners are designed to reduce pulsation, vibration, noise, and system shock caused by positive displacement pumps. By absorbing pressure fluctuations, these dampeners help create smoother flow and protect pumps, piping, valves, fittings, and instrumentation from damage.
Key benefits include:
- Reduces pump pulsation and vibration
- Helps prevent water hammer and hydraulic shock
- Protects pumps, piping, valves, and fittings
- Improves flow consistency and system performance
- Helps extend equipment life and reduce maintenance issues
AODDampener™ Series
The AODDampener™ Series is designed specifically for air-operated double diaphragm pumps. These dampeners help smooth discharge flow, reduce vibration, and improve system reliability in AODD pump applications.
This solution is ideal for applications that require more consistent flow, improved pressure control, and reduced stress on downstream equipment.
Inlet Stabilizers
Blacoh Inlet Stabilizers help reduce pressure fluctuations and acceleration head losses at the pump inlet. By helping maintain a more stable flow into the pump, inlet stabilizers support better pump performance and help prevent issues caused by fluid column separation.
SurgeShield™ Vessels
Blacoh SurgeShield™ vessels are designed to protect pump systems from surge and water hammer. These vessels absorb and release energy caused by sudden changes in fluid velocity, helping prevent costly damage to piping and equipment.
SENTINEL™ Valves & Diaphragm Seals
In addition to dampeners and surge control products, Blacoh also offers diaphragm seals and valve solutions designed to support pressure control, instrumentation protection, and overall system reliability.
