Grundfos Vertical Multistage CR 1-8 , 1x240V

Product Description

CR 1-8 A-FGJ-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 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 DIN-ANSI-JIS flanges. The pump is fitted with a 1-phase, fan-cooled asynchronous motor.
