Pressure Washer Pumps

Dayton pressure washer pumps are designed for high-pressure water applications, including sewer jetting, car washing & cooling misting. These pumps feature splash / oil bath lubrication to reduce friction & wear, and are equipped with ceramic / SST plungers for excellent thermal shock resistance. They deliver a maximum speed of 3450 rpm and are available in lengths ranging from 6.3 to 13 inches.

Working Mechanism

  • A retracting plunger creates suction at the liquid end, allowing the suction valve to open.
  • The medium enters the liquid end, allowing the plunger to advance.
  • The plunger displaces the available volume by increasing the pressure of the fluid to be pumped.

Features

  • These pumps have splash / oil bath lubrication to reduce friction & wear, and ceramic / SST plungers for superior thermal shock resistance.
  • The anodised, precision cast cooling fins provide maximum heat dissipation.
  • The positive alignment and centring (in relation to the crankcase) ensure that the oversized needle bearings on the drive side, ball bearings on the non-drive side and precision supports, are all properly aligned.
  • The Ultra-Form valve cages provide positive seating.
  • The one-piece connecting rods are made of a special aluminium alloy for strength and load distribution.
