The hose has failed.

Replace with a new hose and
lubricant.

Inlet line is blocked.

Clear any obstructions in the inlet
line.

Inlet line is too long or too small.

Try to locate the pump as near
to the fluid source as possible.
Oversize the inlet piping when
possible.

Low inlet pressure.

Viscosity or specific gravity of
pumped fluid is too high.

Consult your Graco distributor for
suitable operating conditions for
your pump.

The hose has failed.

Replace with a new hose and
lubricant.

Low flow.

The back pressure is too high for
the combination of fluid viscosity
and cycle rate.

Reduce back pressure and/or
increase your cycle rate.

Hose is incompatible with the fluid
being pumped.

Consult your Graco distributor to
see if you have the correct hose
for your application.

Hose has failed due to normal
wear.

Replace.

Excessive pulsations have
weakened the hose.

If you pump is equipped with a
pulsation dampener, adjust its
pressure. If you do not have a
dampener, consult your Graco
distributor.

Outlet pressure is too high.

Check items listed in “High outlet
pressure.” Running the pump
against a closed valve, even for a
short amount of time, may damage
the hose.

Poor hose life.

Solids have settled in the hose.

Flush the pump and hose prior to
turning the pump off.

The cover bolts are not tight
enough.

Refer to torque specifications in

Install the Front Cover, page 18

.

Hose lubricant is leaking from the
front cover.

The cover gasket is worn or
damaged.

Replace.

Hose lubricant is leaking from the
hose barb area.

Gaskets are missing or worn.

Replace.

Hose failed because it wrapped
around the roller.

Pump was operated against a
closed outlet valve or blocked line.

Replace hose. Check pressure
relief system. Check that valves
are open. Clear any blockages.
