My pump is leaking oil.
Note: Some degree of oil leakage is normal. If oil leakage appears to be excessive:
Seals are worn and require replacement.
Install a Major Maintenance Kit.
Seals were installed without proper assembly
tools.
Piston rod seals are worn.
Replace piston rod seal assembly.
My pump is leaking water.
CAUTION: Make sure the system is turned off and bled-down before servicing.
High-pressure water leaks.
Refer to the illustrated troubleshooting guide
located at the beginning of this section.
Low-pressure water leaks.
Tighten fittings or replace o-rings.
My pump is vibrating and/or noisy.
By nature, pumps vibrate and make noise. If you think the vibration/noise is excessive, check the following:
No anti-vibration mat.
Use or replace anti-vibration mat.
Improper belt tension or failed belt(s).
Adjust or replace belts to proper tension (see
section
Tensioning and aligning the belt drive
).
UHP seal or check valve failure.
Replace components as necessary.
Crankcase failure.
Replace crankcase.
Loss of electrical power leg; or the motor is
spinning backwards.
Call a certified electrician.
My pump does not build the pressure I expect.
My pump does not cut
at 60 ksi.
The maximum cutting pressure of the pump is 55,000 psi. The maximum output pressure has
the potential to reach 60,000 psi.
My pump does not
produce the pressure
requested from
FlowMaster.
Belts are slipping or failed (broken/stretched).
