The pump is designed with an axial fluid inlet and a radial outlet. The hydraulicsystem is rigidly connected to the motor via a stub shaft and runs in a product-lubricated SIC/SIC plain bearing on the impeller side, which compensates any lateralmovement or deflection of the shaft. Thanks to the graded lengths of intermediatepipe (8) and shaft (6) the pump set can be matched to various installation depths. Thepump set is mounted on a cover plate (5). The discharge nozzle of the volute casing(15) is connected with the discharge nozzle (13) of the cover plate via a riser (14). Ifon request the pump set is supplied without cover plate and riser, it is supplied witha bracket.

The fluid enters the pump via a suction nozzle (12) and is accelerated by the rotatingimpeller (11), which causes a cylindrical flow towards the outside of the pump. Theflow profile of the pump casing converts the kinetic energy of the fluid into pressureenergy. The fluid is pumped to the discharge nozzle (15), where it leaves the pump.The clearance gap (16) prevents any fluid from flowing back from the casing into theinlet. At the rear side of the impeller, the shaft (6) enters the casing via the casingcover (10). The shaft runs in rolling element bearings (2 and 3), which are supportedby a motor housing (1) linked with the pump casing and/or casing cover via theintermediate pipe (8) and the motor stool (4).

The pump is seal-less with little leakage flowing into the intermediate pipe (8) at theshaft passage (9) and then through the overflow opening (7) back to the tank.
