SUGGESTED PLUMbING FOR PISTON PUMP
Strainer
The suction and discharge lines must be large enough for the flow required. For high volume the hose to the inlet manifolds
must be no less than 1-1/2” diameter reinforced hose on the PP1 and 2” diameter reinforced hose on the PP2. The suction
line should be as short as possible and free from any bends that might cause an air trap. In-line filters or strainers must be
cleaned frequently and they must be large enough not to restrict flow as this may affect output accuracy.
Do not plumb filters, strainers or manifolds directly to the pump manifolds as the extra weight puts undue stress on
the pump manifolds. These items should be mounted to the implement frame and plumbed to the pump using a suit-
able length of hose. It is also strongly recommended to have a pressure gauge plumbed into the discharge line.
Spray pressure can be approximated by selecting the proper size tips for the speed traveled and volume required (refer to
the slide chart provided with your pump).
PRESSURE MUST NOT EXCEED 100 PSI. PUMP SPEED MUST NOT EXCEED
210 RPM. OPTIMUM OPERATING PRESSURE IS 20-40 PSI.
Use of a check valve in each discharge is recommended.

NOTE: Thread sealant should be applied to all threaded fit-
tings before assembly.
DO NOT install a shut-off valve in the discharge line as it may be
left shut and cause extensive damage to the pump and hoses.
Caution: To prevent personal injury, observe the following precaution.

NOTE: Mounting angle should
be attached to the 7” x 7” Tool
bar, in a convenient location
where it will not effect the op-
eration of the planter.
NOTE: be sure to route hose
so as not to interfere with or be
affected by any folding opera-
tions.
Flange fitting connections may
be used if desired.
