Grundfos CR 1S-36 Vertical Multistage Centrifugal Pump High Head High Pressure Boosting Pump High-Rise Water Supply Pump Domestic and Industrial Water

CR 1S-36 A-FGJ-A-E-HQQE
Vertical multistage centrifugal pump with inlet and outlet on the same horizontal plane (in-line). The pump casing and base are made of cast iron, while all other liquid-contacting components are manufactured from stainless steel. Electrical power is transmitted via a split coupling. Pipe connections are achieved through combined DIN-ANSI-JIS flanges. The pump is equipped with a 3-phase asynchronous motor featuring a cooling fan and a foot mounting.
