Profile: Blacoh Fluid Control Inc manufactures fluid control products for all facets of municipal and industrial process industries. We market pulsation dampening and surge control. We offer sentinel diaphragm seals that protect and isolate all forms of system instrumentation from contamination and corrosion. Positive displacement pumps create pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging the entire pumping system.
