Description

CR 20-7 K-GJ-A-E-HQQE Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). The pump head and base are in cast iron – all other wetted parts are in stainless steel. A special "Low NPSH" first-stage design reduces the pump's NPSHr value. 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 combined ANSI-JIS flanges. The pump is fitted with a 3-phase, fan-cooled asynchronous motor.
