Location

NOTE: The numbers in parentheses are Reference Numbers
located in the Parts List exploded views of this manual.

Locate the pump as close to the supply source as possible.

Install it in a lighted clean space where it will be easy to inspect
and maintain.

Motor and Controller

The P Series pump shaft can rotate in either direction, therefore
direction of motor shaft rotation is not critical.

Accessories

Consult installation drawing below for typical precision metering
fluid system components. Contact Wanner Engineering or the
distributor in your area for more details.

Important Precautions

Ad equat e F luid Supply. To avoid cavitat ion and

premature pump failure, be sure that the pump will have
an adequate fluid supply and that the inlet line will not be
obstructed. See Inlet Piping on page 6.

Positive Displacement. This is a positive-displacement
pump. To avoid severe system damage if the discharge line
ever becomes blocked, install a relief valve downstream
from the pump. See Discharge Piping on page 6.

Safety Guards. Follow all codes and regulations regarding
installation and operation of the pumping system.

Shut-Off Valves. Never install shut-off valves between
the pump and discharge pressure regulator, or in the
regulator bypass line.

Consult the Factory for the following situations:

• Extreme temperature applications (above 160°F or
below 40°F)

• Pressure feeding of pumps

• Viscous or abrasive fluid applications

• Chemical compatibility problems

• Hot ambient temperatures (above 110°F)

P100 Installation

Inlet Piping

Provide for permanent or temporary installation of a compound
pressure gauge to monitor the inlet pressure. To maintain
maximum flow, the pump inlet should be under flooded suction
conditions at all times. Do not supply more than one pump

from the same inlet line.

Supply Tank

Use a supply tank that is large enough to provide time for any
trapped air in the fluid to escape. The tank size should be at
least twice the maximum pump flow rate.

Install a separate inlet line from the supply tank to each
pump.

Place a cover over the supply tank, to prevent foreign objects
from falling into it.

Hose Sizing and Routing

To minimize acceleration head and frictional losses, size the
suction line at least one size larger than the pump inlet, and
keep the suction line as short and direct as possible.

Recommendations:

• Keep inlet lines less than 3 ft. (1 m) long

• Use at least 5/8” (16 mm) I.D. inlet hose

• Minimize fittings (elbows, valves, tees, etc.)

Inlet Piping (Pressure Feed)

Provide for permanent or temporary installation of a pressure
gauge to monitor the inlet pressure. Pressure at the pump inlet
should not exceed 250 psi (17.3 bar). For higher pressures
install a pressure reducing valve. Do not supply more than

one pump from the same inlet line.

Note: System back pressure must exceed the pump inlet
pressure by at least 15 psi (1 bar) in order to prevent flow
thru.

Discharge Piping

Hose and Routing

Use the shortest, most-direct route for the discharge line.

Select pipe or hose with a working pressure rating of at least

1.5 times the maximum system pressure. EXAMPLE: Select a
1500 psi (103 bar) W.P. rated hose for a system to be operated
at 1000 psi (69 bar) gauge pressure.

Support the pump and piping independently.

Pressure Regulation

Install a pressure relief valve in the discharge line. Bypass

pressure must not exceed the pressure limit of the pump.

Size the valve so that, when fully open, it will be large enough
to relieve the full capacity of the pump without overpressurizing
the system.

Locate the valve as close to the pump as possible and ahead
of any other valves.

Adjust the pressure relief valve to no more than 10% over the
maximum working pressure of the system. Do not exceed the
manufacturer’s pressure rating for the pump or valve.

Route the bypass line to the supply tank.

CAUTION: Never install shutoff valves in the bypass line or
between the pump and pressure regulator or relief valve.

Provide for permanent or temporary installation of a pressure
gauge to monitor the discharge pressure at the pump.

Minimum Discharge Pressure

To ensure proper capacity control, a minimum discharge
pressure of 50 psi (3.5 bar) is required.
