CR 3-27 A-FGJ-A-E-HQQE
Vertical multistage centrifugal pump with suction and discharge nozzles located on the same level ("in-line"), which provides the possibility of installation in a horizontal single-pipe system. The pump head and base are made of cast iron - all other parts in contact with the pumped liquid are made of stainless steel. The cartridge shaft seal provides high reliability, safe use and easy access for maintenance. The rotation is transmitted through a detachable coupling. The connection of the pipeline is carried out using combined flanges of DIN-ANSI-JIS standards.
The pump is equipped with an asynchronous 3-phase electric motor on the paws, with air cooling.
