CRN Stainless Steel Vertical Multi-stage Centrifugal Pump: Strong Corrosion Resistance
|
CRN 255-6-2 A-P-A-V-HQQV
Vertical multi-stage centrifugal pump. The inlet and outlet are on the same horizontal plane (in-line). The pump body materials in contact with the liquid are high - grade stainless steel. The built - in thrust control device can absorb hydraulic axial forces, so standard motors can be used. The Grundfos cartridge shaft seal improves the reliability of the machine and the safety of operation, making maintenance easier. Electric energy is transmitted through a split - type coupling. The connection of pipelines is realized via PJE couplings. An asynchronous motor with a 3 - phase, cooling fan and feet is installed on the water pump.
