Jung US Hot Water Submersible Pumps

Jung US 73 HE, US 73HES, US103 HE, US 103 HES Submersible drainage pumps are suitable for dealing with very contaminated water and capable of handling solids up to 30 mm particle size without stones. These pumps can be used wherever wastewater up to 194°F (90°C) is involved, such as in laundries or automatic launderettes, or in industrial dishwashers and washing machines or for the emergency overflow of heating systems.

Available in manual or automatic variants.

The pumps are suitable for stationary and portable use. For easy removal of the pumps from deep sumps we recommend the use of our guide rail systems which provide ease of maintenance and inspection. A controllable oil chamber and wear-resistant special mechanical seal ensure a long service life. The integrated winding thermostats protect the motor from overload.
