Grundfos CR 20-17 Stainless Steel Vertical Centrifugal Water Pump Industrial High Pressure Centrifugal Pumps Water Treatment Pump Multi-Stage Booster

CR 20-17 A-F-A-E-HQQE
Vertical multistage centrifugal pump with inlet and outlet on the same horizontal plane (in-line). The pump head and base are made of cast iron, while all other liquid-contact components are manufactured from stainless steel. The cartridge-type shaft seal enhances the machine's reliability and operational safety, making maintenance more straightforward. Electrical energy is transmitted via a split coupling. Pipe connections are achieved through DIN flanges. The pump is equipped with a three-phase asynchronous motor featuring a cooling fan and a foot bracket.
