crn 3 7 a p a v hqqv 96517975 Pressure relief valves protect theVertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). Pump materials in contact with the liquid are in high grade stainless steel. A cartridge shaft seal ensures high reliability, safe handling, and easy access and service. Power transmission is via a rigid split coupling. Pipe connection is via PJE (Victaulic) couplings. The pump is fitted with a 3 phase, fan cooled asynchronous motor.
