MATERIALS

Propeller (Stainless steel 1.4436) Motor- /Propellershaft (Stainless steel 1.4104) Motor housing (Grey cast iron EN-GJL-250) Motor bearing cover (Grey cast iron EN-GJL-250) Bolts (Stainless steel) Elastomeres (Nitrile Rubber) Installation system (Stainless steel 1.4571) Mechanical seal on medium side (SiC / SiC) Mechanical seal on motor side (SiC / SiC) Upper Bearing (Deep Groove Ball Bearing) Lower Bearing (Double row angular ball bearing)

PUMPED LIQUID

Max. medium temperature: 40 °C, short term up to 60 °C.

MOTOR

Electric motors, with 4-12 pole motor speed. Insulation class H, degree of protection IP 68.Thermal sensors embedded in the stator winding protect the motor from overheating. PTC sensors on request. With seal probe in oil chamber.

SHAFT/BEARING

Large diameter stainless steel rotor shaft, pre-lubricated bearings.

SEALS

Propeller shaft sealing by mechanical seal in oil chamber, sealed from motor chamber by mechanical seal.

PROPELLER

2-blade propeller, self cleaning design, stainless steel

FEATURES

Compact design by direct drive for installation in buildings with small space available. Installation on the basin floor because of small propeller diameter possible. Other mounting options via system dependent lowering device in pump shafts and on basin walls. Standard and optional Monitoring equipment ensures operational safety.
