MATERIALS

Propeller (Plastic, glass fibre reinforced) Motor- /Propellershaft (Stainless steel 1.4057) Gear case (Grey cast iron EN-GJL-200) Motor housing (Grey cast iron EN-GJL-200) Motor bearing cover (Grey cast iron EN-GJL-200) Bolts (Stainless steel) Elastomeres (Nitrile Rubber) Installation system (Stainless steel 1.4301) Mechanical seal (SiC / SiC) Lip seals (Nitrile Rubber) Motor bearing (Deep Groove Ball Bearing / Double row angular ball bearing) Gear shaft bearings (Angular / deep groove ball bearing / spherical roller bearing)

PUMPED LIQUID

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

MOTOR

Electric motors, with 6-pole motor speed. Insulation class F, degree of protection IP 68. Thermal sensors embedded in the stator winding protect the motor from overheating. With seal probe in stator housing and junction chamber.

SHAFT/BEARING

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

SEALS

2-level system with sealing of the propeller hub by 2 radial seals with grease filling and medium-side sealing of the propeller shaft by mechanical seal. Transmission chamber as oil chamber with inspection port for lubrication of GRD and seal monitoring. Sealing between the transmission chamber and engine compartment by 2 radial shaft seal rings.

PROPELLER

Hydraulically optimized, self cleaning design

CONSTRUCTION TYPE

The robust design of HOMA submersible mixers guarantees long-life troublefree operation even under most demanding conditions. The hydraulically optimized design of all propellers, transmission and motor drive results in outstanding efficiencies and excellent mixing performance with minimum flow losses.
