All the hydraulic and wetted components are manufactured
in 304 Stainless Steel
To DIN 24255
Th stainless steel pumps feature a piece volute casing that is produced using an advanced computer controlled Plasma stamping system that ensures total quality control during manufacture. With the smooth surfaces of stamped stainless steel, this results in consistent high standard products, of superior quality and high efficiency.
The back pull-out construction permits the disassembly and overhaul of the impeller, mechanical seal and motor without removal of the suction or discharge piping, or pump casing.
The centre line discharge and foot support under the casing ensure maximum resistance to misalignment and distortion from pipe loads.
