The XV-F series of electric pumps are vertical centrifugal pumps, non-self-priming, with linear suction and drive, and their high performance makes them ideal for use in pressure equipment, industrial installations, and all applications requiring high pressure.

SQQE Mechanical Seal the cartridge type is used, which provides easy replacement. Cartridge-type mechanical seals are used in cases where exceptional reliability, increased service life, ease of installation are important, the use of seals of this type is due to the requirements of regulatory documents


All the materials and components that we use in BTS mechanical seals are of the highest quality.

The mechanical seal of the shaft of KSB Etaline pumps is single uncooled, friction pair silicon carbide / silicon carbide, special elestomer or ethylene-propylene rubber. Other materials are also possible, according to the media being pumped.

Our specialists replaced the seal in the KSB Etaline G 32-160/034pump

There are several points that you should pay attention to when choosing and installing a seal :

  • When pumping media with abrasive components, increased wear of the hydraulics and the shaft seal should be expected. In this case, it is necessary to reduce the usual intervals between inspections.
  • When installing the seal, to reduce the friction forces, moisten the shaft sleeve and the seat of the fixed ring of the mechanical seal with water.
  • The mechanical seal has a slight or imperceptible leakage (in the form of steam) during operation.
  • Increased wear due to dry running! If possible, never allow it .

KSB pumps of the Etaline PumpDrive series are designed for pumping liquids that are not chemically aggressive in heating, water supply, etc. By design, Etaline is a monoblock pump with a horizontal nozzle arrangement in one line -"inline".
