Blacoh Industries
About
Blacoh Industries, founded in 1976 and headquartered in Riverside, California, is a US manufacturer of engineered fluid control products for municipal and industrial pumping systems, holding ISO 9001:2015 certification with products compliant to ASME, CRN, ATEX, and PED standards. The company's SENTRY product line provides pulsation dampeners and surge suppressors for stabilizing flow and protecting piping, including the AODDampener purpose-built for air-operated diaphragm pumps, inlet stabilizers that prevent cavitation at pump suction, and the SENTRY XP series rated from 2,000 to 15,000 psi for high-pressure applications. The SurgeShield combines surge vessel and pulsation dampening in a single unit for space-constrained installations, while surge bladder vessels address water hammer in large distribution and process systems. The SENTINEL product line covers diaphragm seals for isolating instruments from corrosive or slurry process fluids, back pressure valves that maintain steady dosing pump output, pressure relief valves, degassing valves, calibration columns up to 20,000 mL in PVC or glass, and injection quills with spring-loaded check disks for safe chemical dispersion. The SPILLSTOP pneumatic system automatically captures diaphragm pump leaks and shuts down the pump, and SPILLGUARD provides AODD pump spill containment. Blacoh also offers the SurgeWave transient pressure monitoring system and an online e-Configurator tool for rapid engineering specification.
Key Products
Remove pulsation and system shock from pumping systems to protect equipment, extend pump life, and stabilize flow.
Purpose-built pulsation dampener for air-operated diaphragm (AODD) pumps with automatic air control and stainless steel construction.
Stabilize suction-side fluid conditions at pump inlets to prevent cavitation and flow irregularities.
Pre-sized plug-and-play inlet stabilizer for 1.5-inch and 2-inch AODD pump inlets requiring no field sizing.
Pulsation dampeners rated from 2,000 to 15,000 psi for high-pressure chemical and industrial pumping applications.
Store and release pressurized fluid to smooth flow, reduce pressure spikes, and absorb hydraulic shock in piping systems.
Combined surge vessel and pulsation dampener in a single unit for dual-function hydraulic protection in space-constrained installations.
Chemically resistant diaphragms that isolate pressure and temperature instruments from corrosive, abrasive, or slurry process fluids.
Maintain consistent system back pressure using flow stabilization technology, preventing siphoning and ensuring steady dosing pump output.
Protect pumping systems by automatically venting excess pressure buildup to prevent over-pressurization damage.
Automatically vent trapped gases and vapors from pumping systems to maintain liquid prime and prevent gas lock.
Transparent graduated columns in PVC or glass up to 20,000 mL for precise flow-rate measurement and calibration of chemical dosing systems.
Safely disperse chemicals into process pipelines via an integral spring-loaded check disk that prevents backflow into the chemical feed system.
Single unit combining pulsation dampening and back pressure regulation to reduce installation footprint and component count.
Pneumatic spill prevention system that automatically captures leaks and shuts down a failed pump before a spill can propagate.
Essential spill containment and prevention accessory designed for air-operated diaphragm pumps in chemical handling applications.
Large-capacity bladder vessels installed on pipelines to absorb hydraulic transients and water hammer events in water distribution and process systems.
Patented real-time transient pressure monitoring technology that detects and records hydraulic transients in piping systems for analysis and asset protection.
