MH300 Features:

AllightSykes Sykes MH300i Medium Pump
Innovations include the introduction of a flooded, oil-lubricated pump bearing set-up and leak-free pump bearing isolator in place of the grease lubrication system featured in many other pumps. This neatly sidesteps the usual threat of pump failure due to either too much or too little grease - or because of contamination.

  • Closed coupled pump SAE # 1 - virtually eliminates pump / engine misalignment
  • Flooded oil lubricated pump bearing set up
  • Pump Bearing Isolator set up
  • Excellent suction lift capabilities at high flow at variable diesel speeds (1,300 - 1,600rpm)
  • Pump efficiency (77%)

The MH300 pump is available with an impeller diameter size of either 490mm or 510mm.

Term Life

Compressor Prime
Involves passing a jet of compressed air  through a venturi-type nozzle to evacuate the pump casing and suction line. It makes sure priming is fast, positive and continuous - even under snore conditions. The priming system has no moving parts. This greatly reduces maintenance requirements.
Vacuum Prime
Features a vacuum priming chamber which dramatically reduces carry-over due to the stainless steel baffle deflector plates and pancake float. Ideal for wellpoint dewatering and long suction conditions.

Maintenance info & packages

The world’s best-regarded water management brands are united by a common vision - they’re engineered and built to make mining and construction projects safer and more productive while being sensitive to the environment.

Our flagship water management brand, Sykes/Primax has been a major force in the world’s auto-prime pump market for over 40 years.

Much of its success reflects its cleverly designed priming systems which improve fluid handling efficiencies and greatly reduce maintenance requirements. A ‘snore’ facility built into its ground-breaking auto-priming pumps, for example, means they can run dry without damage for extended periods.
