Description
CR 185-5 A-G-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 built-in thrust-handling device absorbs hydraulic axial forces which enables the use of a standard motor. The Grundfos 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 ANSI flanges. The pump is fitted with a 3-phase, fan-cooled asynchronous motor.
