10 GPM Pressure Washer Pump

The General Pump KE22A is a triplex plunger pump that features a unique patent pending symmetrical power end design with top and bottom mounting holes. This 10 GPM pressure washer pump has a shaft that can easily be converted from one side to the other to meet the requirements of your application. The shaft accepts SAE-B hydraulic drive bell housings and flexible couplers. This pump delivers a maximum flow rate of 10 GPM making it great for applications requiring high flow rates such as pressure washing. The manifold is constructed with 420 stainless steel and is treated with nickel to deliver maximum protection from corrosion so it will endure harsher chemicals.

Trouble Shooting:

• The Pump Does Not Produce Any Noise
  • Causes:
    • The pump is not primed and is running dry!
    • No water in the inlet line
    • The valves are blocked
    • The pressure line is closed and does not allow the air to get out of the fluid end
• The Pump Knocks:
  • Causes:
    • Air suction
    • Insufficient feeding
    • Bends, elbows, and fittings along the suction line throttle the amount of water that passes through.
    • Too small inlet filter
    • Dirty inlet filter 
    • The feeding pump, where provided, is not suitable or provides insufficient pressure or volume. 
    • The pump is not primed due to insufficient feeding or the delivery line is closed during start-up.
    • The pump is not primed because some valves are stuck (i.e pump inactivity for a long time)
    • Jammed or worn-out valves
    • Worn out pressure packings
    • The pressure regulating valve does not work properly
    • Clearance in the drive system
    • RPM is higher than rated
• The Pump Does Not Deliver the Rated Volume:
  • Causes:
    • Insufficient feeding (due to the cause listed above)
    • RPM are less than rated
    • Excessive amount of water by-passed by the pressure regulating valve
    • Worn out valves
    • Excessive leakage from pressure packings
• Insufficient Pump Pressure:
  • Causes:
    • The nozzle is (or has become) too large
      RPM are less than rated- Excessive leakage from pressure packings
    • Excessive amount of water by-passed by the pressure regulating valve or faulty valve operation
    • Worn out valves
• Excessive Water Leakage from The Pump:
  • Causes:
    • Pressure packing is excessively worn out (due to normal wear or excessive cavitation)
    • Worn out plungers
• Overheated Pump:
  • Causes:
    • The direction of rotation is not correct
    • Pump is overloaded (pressure or RPM over the rated values)
    • The oil level is too low or the oil    is not of a suitable type or fully used
    • Water in the oil
    • Excessive belt tension or incorrect alignment of the joint (where provided)
    • Excessive inclination of the pump during operation
• Pipe Vibrations or Knocking:
  • Causes:
    • Air suction
    • The pressure regulating valve does not work properly
    • The by-pass line is undersized
    •  Jammed-up valves
    • Drive transmission motion is irregular
