SKA self-priming pumps


Applications

SKA self-priming rotodynamic, pumps with side ring channel and open impeller, serve to pump liquids within the corrosion resistance limits of materials used for their construction. Liquids of a temperature up to 110oC, discharged liquid density up to 1 300 kg/m3 and viscosity up to 150 mm2/s contaminated with solid particles up to 0.5 mm in trace amounts can be pumped. Pumps can cooperate with 50 Hz or 60 Hz motors.

SKA pumps can be used in:

  • waterwork systems, ,
  • individual farms,
  • industry.

Technical specifications

capacity 0,3 ÷ 30 m3/h
delivery head up to 310 m *
pumped liquid temperature up to 110 oC
liquid density up to 1300 kg/m3
liquid viscosity up to 150 mm2/s
mass 34,0 ÷ 409,0 kg
motor power 0,55 ÷ 30,0 kW
rotation speed 1450 obr/min (50 Hz) and 1800 obr/min (60 Hz)

*

Delivry head is lowered by 10% for hot liquids from + 70oC to +110oC.

  • manometric pressure allowed for SKA.2 pumps cannot exceed 2.5 MPa,
  • for the remaining 1 to 4 stage pumps, manometric pressure cannot exceed 2.0 MPa and for 5 to 8 stage pumps - 3.2 MPa,
  • for 1 to 4 stage pumps with an oval flange the allowed pressure cannot exceed 0.8 MPa.

Budowa

SKA 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 at suction housing, then come suction/discharge members and the last discharge member.

Features:

  • 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.
