Maximum water temperature is
140°F.
All positive displacement plunger
pumps must have a safety relief valve
installed on the discharge side of the
pump, this valve could be either an
unloader or regulator and must be of
adequate flow and pressure for the
pump.
Adequate protective guards must
cover all moving parts. Perform
routine maintenance on the pump and
components.
Use only components that are rated
for the flow and pressure of the pump,
this would include hose, fittings, safety
valves, spray guns etc.
