BLACOH FULL-SYSTEM SOLUTIONS

PREVENT. ENSURE. PROTECT.
Blacoh SENTRY Pulsation Dampeners use compressed gas separated by a bladder from the process fluid like a shock absorber. During the pump’s discharge stroke, fluid pressure displaces the bladder, compressing the trapped gas. During the pump’s next cycle, fluid stops momentarily causing expansion of the compressed gas, forcing the bladder to push accumulated fluid back into the discharge line. This fills the void created by the cycle shift and dampens pulsation up to 99%.

Blacoh SENTRY Surge Suppressors use compressed gas separated by a bladder from process fluid to suppress hydraulic surge or water hammer caused by quick-closing valves, back surge, and pump start-up/shut-down. Without suppression, shock waves created will continue to oscillate back and forth until dissipated by friction or system component failure.

The Blacoh patented “J” Model Inlet Stabilizer accumulates liquid at the pump’s inlet to improve the flow conditions to any pump. This insures complete chamber fill and extends the service life of all inlet system components. The “J” Model Inlet Stabilizer’s patented air control allows one to adjust for pressure vacuum depending on whether pump operation is under suction life of positive inlet conditions.

Prevent costly spills and save money and downtime. The Blacoh SPILLSTOP Leak Containment™ system attaches directly to the exhaust of an air operated diaphragm pump. If a diaphragm failure is to occur, the SPILLSTOP™ prevents spills by capturing containment or dangerous fluid in an internal receptacle while raising float or sensor switch. This switch will automatically turn off the pump pneumatically and can be configured to sound a warning alarm and/or initiate a backup pump switchover.

Blacoh SENTINEL Diaphragm Seals (also known as Gauge Guards) employ a chemically resistant diaphragm to effectively isolate process fluids from recording gauges and other process instrumentation. This durable diaphragm allows Diaphragm Seals to accurately transfer process pressure without direct contact with hazardous or corrosive fluids.

Blacoh SENTINEL Pressure Relief Valves protect pumping systems from over pressure caused by damaged equipment or blockage in the system line. When the pressure in the system exceeds the preset pressure of the valve, the diaphragm is held against the valve seat by an internal spring. When the preset pressure is exceeded, the diaphragm is forced up and the system fluid flows out the relief port, back into the system fluid tank.

Blacoh SENTINEL Back Pressure Valves are designed to enhance the performance of the pumping system by applying a continuous back pressure to the pump, while also acting as an anti-siphoning valve. The valve applies positive discharge pressure to a metering pump system to prevent siphoning and eliminate varying dosage rates caused by fluctuating downstream pressure. When the valve’s preset pressure is exceeded, the diaphragm is forced up and the system fluid flows through the valve to the injection point.

The patent-pending Blacoh Hybrid Valve™ is the world’s first combination pulsation dampener and back pressure valve designed for maximum efficiency and protection of metering pump systems. It combines the steady flow control of a pulsation dampener and the regulation of a back pressure valve to deliver improved performance and functionality of both in a single easy-to-use piece of equipment. Its smaller footprint is ideal for today’s more compact skid designs, there are fewer leak points and it requires less labor to install. Its in-sync design has also been proven to eliminate valve chatter to better protect pumping systems.

The Blacoh AODDampener™ improves the performance of your system, reduces water hammer and the common shaking of pipes caused by AODD pumps. With its universal materials: 316 stainless steel and PTFE-backed diaphragm offered at a competitive price, these units will cover almost all fluid applications and can be easily used a full range of system materials from plastics to metals.

Blacoh SENTINEL Calibration Columns are critical to accurate determination of your system flow rate at the suction side of a metering pump, either at start-up or following maintenance. The top of the cylinder is vented back to the supply tank or drain. The calibration cylinder is filled to the top mark then the valve from the tank is closed. Turning on the metering pump will draw down the liquid providing a simple means to verify the accuracy of the pump flow rate.

Blacoh SENTINEL Injection Quills are used to provide safe delivery of chemicals into pipelines. The quill end ensures the dispersion of the chemicals away from the pipe wall. The integral spring loaded check valve prevents backflow from the pressurized pipe.
