SHAFT INFORMATION
These pumps are designed to operate in any position. The pump shaft must be in alignment
with the shaft of the source driver and should be checked with a dial indicator. The mating
pilot bore and coupling must be concentric. This concentricity is particularly important if the
shaft is rigidly connected to the driven load without a exible coupling.
Splined: The shafts will accept a maximum misalignment of 0.15mm, 0.005 inch, total
indicator reading. Angular misalignment at the external and internal spline axis must be
less than ± 0,002 mm per mm of shaft radius, ± 0.002 inches per inch of shaft radius.
The coupling interface must be lubricated. PARKER recommends lithium molydisulde
or similar grease. The internal coupling should be hardened to Rc 27-34 and must conform
to SAE-J498c, class 5 at root side t.
Keyed: High strength heat treated keys must be used. Replacement keys must be hardened
to 27-34 Rc. The key corners must be chamfered 0.81-1.0 mm, 0.032”-0.040”, at 45° to
clear radii that exist in the keyway.
The P1/PD series is designed for inline-drive. Side loading on the shaft is not recommended.
If this is unavoidable consult your nearest PARKER representative.
Connect inlet and outlet lines to the port block of the pump. The maximum case pressure is
2 bar (30 psi) continuous, 4 bar (60 psi) intermittent. The case pressure must never exceed
inlet pressure by more than .5 bar (7 psi). When connecting case drain line make certain that
drain plumbing passes above highest point of the pump before passing to the reservoir. The
case leakage line must be of sufcient size to prevent back pressure in excess of 2 bar (30
psi) and returned to the reservoir below the surface of the oil as far from the supply inlet as
possible. All uid lines, whether pipe, tubing, or hose must be adequate size and strength to
assure free ow through the pump. An undersize inlet line will prevent the pump from operat-
ing properly at full rated speed. An undersize outlet line will cause back pressure and cause
heat generation and increased noise. Flexible hose lines are recommended. If rigid piping is
used, the workmanship must be accurate to eliminate strain on the pump port block or to the
uid connections. Sharp bends in the lines must be eliminated wherever possible. All system
piping must be cleaned and ushed before installing pump. Make sure the entire hydraulic
system is free of dirt, lint, scale, or other foreign material.
Caution: Do not use galvanized pipe. Galvanized coating can ake off with continued use.
Although the P1/PD series pumps have very fast off-stroke compensator response, system
relief valves are recommended in all cases for safety considerations.
The uid recommended for use in these pumps has a petroleum base and contains agents
which provide oxidation inhibition and anti-rust, anti-foam and de-aerating properties as
described in PARKER standard HF-1. Where anti-wear additive uids are specied, see
PARKER standard HF-0.
90 V. I. minimum. Higher values extend the range of operating temperature but may reduce
the service life of the uid.
Determined by the viscosity characteristics of the uid used. Because high temperatures
degrade seals, reduce the service life of the uid and create hazards, uid temperature
should not exceed 110°C (230°F) at the case drain.
The pump is self-lubricating and preventative maintenance is limited to keeping system uid
clean by changing lters frequently. Keep all ttings and screws tight. Do not operate at
pressures and speeds in excess of the recommended limit. If the pump does not operate
properly, check the troubleshooting chart before attempting to overhaul the unit. Overhauling
may be accomplished by referring to the disassembly, rework limits of wear parts, and
assembly procedures as provided in this service manual.
Fluid must be cleaned before and continuously during operation, by lters that maintain a
cleanliness level of ISO 20/18/14. Better cleanliness levels will signicantly extend the life
of the components. As contaminant generation may vary with each application, each must
be analyzed to determine proper ltration to maintain the required cleanliness level.

General Information
• Read and understand the instruction manual.
• Identify components and their function.
• Visually inspect components and lines for possible damage.
• Insure that all necessary ports are properly connected.
• Check reservoir for cleanliness. Drain and clean as required.
• Check uid level and ll as required with ltered uid to a minimum ISO
cleanliness level of 20/18/14.
• Fill pump case with clean oil prior to starting.
• If pump is mounted vertically with the shaft up, bleed the air out the D1 drain
port located near the mounting ange.
• Check alignment of drive.
• Check oil cooler and activate it, if included in circuit. Check uid temperature.
• Reduce pressure settings of compensator and relief valve. Make sure accurate
pressure readings can be made at appropriate places.
• If solenoids in system, check for actuation.
• Jog the pump drive. Check for proper shaft rotation. Make sure pump lls properly.
• Start the pump drive.
• Bleed system of air. Recheck uid level.
• Cycle unloaded machine at low pressure and observe actuation (at low speed,
if possible).
• Increase pressure settings gradually in steps. Check for leaks in all lines
especially in pump and motor inlet lines.
• Make correct pressure adjustments.
• Gradually increase speed. Be alert for trouble as indicated by changes in sounds,
system shocks, and air in uid.
• Equipment is operational.

Trouble Shooting
Component problems and circuit problems are often interrelated. An improper circuit may operate with apparent success but
will cause failure of a particular component within it. The component failure can be the effect, not the cause of the problem.
This general guide is offered to help in locating and eliminating the cause of problems by studying their effects.
