Crane-bel international manufactures anti-cavitation suction strainers to protect the pumps against cavitation. This suction strainer offer protection to piston pump against undue cavitation caused due to dirt-loaded suction strainer. Cavitation occurs in hydraulic pumps/ systems when the fluid does not entirely fill the existing space. This can be caused by over speeding of pump, restricted or excessively long intake line, dirty or insufficient capacity suction strainer or too high fluid viscosity of oil. An implosion effect occurs when the compressed air bubbles are subjected to system pressure at the pump outlet that cause metal to be removed from the pressure plates, wear plates, etc, near implosion point and result in extremely high local temperatures. A most common factor resulting from cavitations/ aeration of pump is damaged to suction strainer. Low capacity of suction strainer is very injurious in the system thus a suction strainer of 3 to 4 times of the pump capacity should be installed in inlet line of the pump.
