Low suction pumps with jacket cooling, automatic level sensor
CHARACTERISTICS
Submersible pumps for clear and drainage water – C237 WF3 / C270 WF
APPLICATION
Automatic drainage at low water level from 5 mm to prevent flooding in rooms without pump pit or floor drain, e. g. by flood water, rain, defective water pipe or defective washing machine.

MATERIALS
Motor housing, motor shaft, screws (Stainless steel) Suction sieve, Pump housing, C237, C270 (Wear resistant synthetic material Stainless steel) Impeller, pressure cover (Wear resistant synthetic material (composite)) Elastomere (NBR)
PUMPED LIQUID
Clear water or drainage water containing soft solids up to 3 mm spherical clearance. Max. liquid temperature: 35°C, short term up to 60°C.
MOTOR
Fully submersible, pressure tight electric motor. Stainless steel motor housing. Insulation class F. Motor protection IP 68. Thermal sensors imbedded in the motor winding.
FEATURES
The level sensor starts the pump automatically at a water level of 5 mm and pumps down to 2 mm remaining level. The water jacket cooled motor with the top discharge protects the motor against overheating even during sip operation.
IMPELLER
Impeller of the C237 WF3 / C270 WF series.
For optimum adaptation to the pump medium and operating conditions.
OPEN MULTI-CHANNEL IMPELLER
For dirty and muddy media with solids.
