143 Series Electric Driven Gerotor Pumps

For circulating oil lubrication systems

SKF 143 Series pump units are self-priming, positive-displacement pumps with constant flow and high efficiency. They are suitable for a variety of applications, including hydraulic, hydrostatic, and cooling systems, as well as circulating oil and flow-through lubrication systems.

SKF 143 Series gerotor pumps are highly efficient and operate in a low flow range of 0.85 to 50 l/min at pressures up to 50 bar. They are characterized by extremely smooth operation, low noise levels, and good suction capacity.

Floor-mounted, flange-mounted, and pump-only versions are available. The 143 EEX versions are designed for reliable and safe operation in explosive environments (Zones 1, 2, 21, and 22).

Technical characteristics and advantages

  • Low volumetric flow pulsation improves smooth operation
  • Gerotor with cycloid circuit improves suction performance
  • Low-noise operation
  • Wide viscosity range of standard mineral and synthetic lubricating and hydraulic oils
  • Compact design with pump, motor, coupling and seal
  • Possibility of execution according to individual requirements
  • The reliable and robust gerotor pump unit is developed and manufactured in Germany
  • ATEX gas II 2G c IIC T4 Gb; ATEX dust II 2D c IIIC T120° C Db

Application areas

  • General mechanical engineering and industrial technologies
  • Shipbuilding and offshore industry
  • Pulp, paper and printing industry
  • Heavy industry
  • Application in explosive dusty or gas environments (EEX version), such as:
    • Oil and gas industry
    • Energy
    • Chemical and pharmaceutical industry
    • Food industry
    • Shipbuilding
    • Forestry industry
