CR 155-4-1 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 Grundfos 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.
