Grundfos Vertical Multistage CRI 1-7 , 1x240V

Product Description

CRI 1-7 A-FGJ-A-E-HQQE

Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). Pump materials in contact with the liquid 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.
