Hose
Selection of the right size and type of hose is vital for good
performance. Be sure to hook up to the proper ports on the
pump (note markings “IN” and “OUT” on pump castings).
Suction Hose
Always use genuine suction hose compatible with the fluids
being pumped and at least the same inside diameter as
pump ports. If the suction hose is over 5 feet long, use the
next larger size hose. Keep the suction hose as short as
possible and restrictions such as elbows, check valves, etc.
at a minimum.
Discharge Hose
High pressure pumps require the use of special high pressure
discharge hose (2 rayon braid or equivalent). Use a
hose rated at least 50% greater than the highest operating
pressure required of pump. Example: If required pump pressure
is 200 psi, use discharge hose rated at minimum of 300
psi working pressure.
Unloader Valve
The unloader has a very important safety function in your
piston pump hookup. The unloader valve protects the pump
by unloading pressure when the gun is shut off or discharge
is otherwise blocked. This saves the pump and power
because the liquid is bypassed at a very low pressure. If the
gun is to be shut off for more than 5 minutes, install a pump
protector in the inlet side or stop the pump to prevent heat
buildup. The length of time may vary due to the original temperature
of the fluid being pumped.
Strainers
Use a suction line strainer with at least 3 to 5 times the suction
port area in open screen area. For example, an area of
approximately 1.1 to 1.9 square inches for a 1/2" suction
port. Be sure the screen is suitable for the liquid being
pumped. Keep the filter clean. A clogged strainer will cause
cavitation, which usually leads to a poor performance and
wear of the pump parts.
