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.
