pumps and pumping systems  

SA.80, SB.80 self-priming pumps


Self-priming rotodynamic, side-channel pumps with open impeller are designed for pumping liquids within the corrosion resistance limits of materials used for pump construction. Liquids can contain trace amounts of non-abrasive solid particles of up to 0.5 mm in size. Together with the liquid, pumps can replenish air in the tank through an aeration injection valve. SB.80 pumps are adjusted for pumping a wide range of hydrocarbons such as gasolines, fuel oils etc.

SA and SB pumps can be used in:

  • waterwork systems,
  • individual farms,
  • industry.

S pumps consist of: bearing housings, shaft, suction and discharge housings in which shaft seals are installed. On the shaft impellers are mounted, their number depends upon the number of pump stages. Impeller positions are limited by limiting members. Suction member is located on conversions suction housing and discharge member.
SB.80 pumps differ from their basic SA.80 execution in the use of one ball bearing at the suction side and a special internal slide bearing at the discharge side. Moreover, front seal is used in place of cord seal.
Such a pump design ensures its long life.


  • many years of reliable operation and easy access to replacement parts guaranteed,
  • execution of individual requirements and products adjusted to customer's needs,
  • permanent technical supervision as well as guarantee and post-guarantee service,
  • low procurement and operation costs,
  • relatively long life in difficult operational conditions.
