Pumped liquid

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

Motor

Three-phase electric motors with 4-, 6- or 8-pole winding. Insulation class of winding H (180°C), protection class IP 68. Thermal sensor on all models, embedded in the motor winding. PTC thermistor or PT100 available on request. With seal probe in oil chamber and junction chamber.

Shaft/Bearing

Robust, maintenance-free, permanently lubricated roller bearings. Temparature monitoring of the shaft bearings available on request.

Seals

Two independently working silicon-carbide mechanical seals in tandem-arrangement. Oil-filled seal chamber with possibility of control by the inspection screw.

Construction type

Compact unit of motor and hydraulic with axial propeller for Wet-well operation, installation in vertical circular concrete / steel tube. Self-centering and -sealing inside the tube. No additional alignment during assembly. Angle of Propeller blades manually adjustable for exact adaption to duty point. Blade material highly resistant DUPLEX stainless steel. Complete range of monitoring devices ensure fail-safe reliability.

The network frequency is 50 Hz in the EU.
In other parts of the world, such as in the North American region, Brazil, Saudi Arabia or South Korea 60 Hz.

HOMA pumps are available for both frequency ranges. A selection of the pumps for the valid frequency range at the installation site must be made accordingly. We are happy to assist you in the selection of the right pumps.
