Permanently Lubricated Pump
These pumps feature an oil-filled motor housing with a radial lip seal on the motor shaft. They have an exceptional life expectancy because the oil serves as a continuous lubricant for all moving parts and the shaft seal.

This non-toxic dielectric oil, often parried with an aluminium, cast iron or plastic housing, also helps dissipate the heat build-up found in a continuously running pump.

Applications include aquariums, swimming pools, water displays, ice makers, air conditioners, boat bailing, fuel oil transfer, circulating water for welding and pipe threading machines, pumping mild chemicals such as soap solutions, acids, plating solutions and fertilizers.

  • Operates submersed or in-line
  • Epoxy-coated aluminium housing, nylon volute and impeller
  • Inlet cover with snap off screen for easy cleaning
