Horizontal centrifugal single-stage pumps type E, ET, KEM are designed for transferring drinking water and other liquids free from mechanical impurities and similar to water in viscosity and chemical activity. Pumps can be complete with motors of various voltage and degrees of protection depending on the customer's request.
      According to design features and sphere of application pumps can be divided into following groups:

E - pumps are designed for transferring liquids with temperatures up to 85°C. Can be complete with stuffing box seal or mechanical seal. ET - pumps are designed for transferring liquids with temperatures up to 140°C. Can be complete with stuffing box seal or mechanical seal. KEM - pumps are designed for transferring liquids with temperatures up to 140°C. Pumps are complete with mechanical seals.

      Pumps type E, ET, KEM are noted for high energy data and compact design.

      The indication of the pumps includes the following symbols:
