Pumped liquid

Drainage water or sewage containing soft solids and chemically aggressive liquids. PH-valve 3-14. Max. liquid temperature: 40°C, short term up to 60°C. For limitation to lower temperatures see specific chemical resistance of used materials.


Fully submersible, pressure tight electric motor. Insulation class H. Degree of protection IP 68. Thermal sensor embedded in the winding. Cable: H07 RN-F (Plus) 6G1,5 with cable protective hose and longitudinally tight cable trumpet.


Due to the large free passage of 50 mm they are particularly suitable to pump liquids with coarse solids and fiber fractions, wastewater in the industry as well as liquid chemicals in industrial processes.

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.
