cause severe case spikes. If the pump feeds into a blocked center valve that closes
quickly, use both case drain ports and direct short case drain lines and a relief valve.

DESCRIPTION
GENERAL
The PV/PVT series pumps are variable displacement open circuit piston pumps with a
design emphasis on operation economy. These axial piston pumps for open loop operation
are suitable for rear drive in the PVT series configuration.
The PV/PVT pumps have a displacement of 0.88 to 7.93 cu. in/rev. (14,4 to 130,0
cc/rev.) with a continuous working pressure up to 4000 psi (280 bar): The pumps can
be equipped with a pressure compensator, ventable compensator, load sensing or
power limit control.
MOUNTING
The PV/PVT pumps have been designed to operate in a wide range of applications in
industries where high pressure and variable flow are required at competitive cost.
These pumps are designed to operate in any position. The mounting hub and two bolt
mounting flange are in conformance with SAE standards. 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 flexible
coupling.
REAR DRIVE:
See installation drawings page 11 thru 23 of this bulletin for mounting and page 24
for maximum allowable torque in the data section for torque limits.
SHAFT OPTIONS:
SAE splined and keyed, see installation drawings page 11 thru 23 for details.
INPUT SHAFT INFORMATION:
Splined: The shafts will accept a maximum misalignment of 0.002 in. (0,06mm) total
indicator reading when the pump is foot mounted and 0.001 in. (0,03 mm) when flange
mounted. Angular misalignment at the male and female spline axis must be less
than ±0,002 inch per inch radius (± 0,002 mm/mm). The coupling interface must be
lubricated.
DENISON recommends lithium molydisulfide or similar grease. The female coupling
should be hardened to 27/34 Rc and must conform to SAE-J498c, class 5 flat root
side fit.
Keyed: High strength heat treated keys must be used. Replacement keys must
be hardened to 27-34 Rc. The key corners must be chamfered 0.03 - 0.04 in.
(0,75-1,0 mm) at 45° to clear radii that exist in the keyway.
SIDE LOAD CAPABILITY:
The PV series is designed for inline-drive and side loading on the shaft is not
recommended. If this is unavoidable consult your nearest DENISON HYDRAULICS
representative.
SHAFT BEARING LIFE:
See chart in data section of this bulletin.
See installation drawings in the back of this bulletin for port connections.
PIPING
The maximum case pressure is shown on page 3. Case pressure must never exceed
inlet pressure by more than 13 psi (0,9 bar). 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 sufficient size to prevent back pressure in excess of
the values on page 3 and returned to the reservoir below the surface of the oil as far
from the supply suction as possible. All fluid lines, whether pipe, tubing, or hose must
be adequate size and strength to assure free flow through the pump. An undersize
inlet line will prevent the pump from operating at full rated speed. An undersize outlet
line will create back pressure and cause heat generation. 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 fluid connections. Sharp bends in the lines
must be eliminated wherever possible. All system piping must be cleaned with solvent
or equivalent 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 flake off with continued
use.

DESCRIPTION
SERVICE INFORMATION
These hydraulic products are designed to give long dependable service when properly
applied and their systems properly maintained. These general instructions apply to typical
systems. Specific instructions for particular equipment can be developed from
them.
Refer to bulletin S1-AM009 for service information.
RECOMMENDED FLUIDS
The fluid 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 DENISON HYDRAULICS standard HF-1. Where anti-wear additive
fluids are specified, see DENISON HYDRAULICS standard HF-0.
VISCOSITY
VISCOSITY INDEX
max. at cold start- 7500 SUS (1600 cSt)
at low pressure, low flow, and if possible, low speed
max. at full power- 750 SUS (160 cSt)
optimum for max. life- 140 SUS (30 cSt)
minimum at full power- 60 SUS (10 cSt)
90 V. I. minimum. Higher values extend the range of operating temperature but may
reduce the service life of the fluid.
TEMPERATURE
Determined by the viscosity characteristics of the fluid used. Because high temperatures
degrade seals, reduce the service life of the fluid and create hazards, fluid temperature
should not exceed 180°F (82°C) at the case drain.
MAINTENANCE
The pump is self-lubricating and preventative maintenance is limited to keeping system
fluid clean by changing filters frequently. Keep all fittings 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. Refer to the service manual for
troubleshooting and overhaul information.
FLUID CLEANLINESS
Fluid must be cleaned before and continuously during operation by filters that maintain
a cleanliness level of ISO 17/14. This approximately corresponds to NAS 1638 class 8
(class 9 for 15 micron and smaller). This fluid level cleanliness can usually be accomplished
by the effective use of 10 micron filters. Better cleanliness levels will significantly
extend the life of the components. As contaminant generation may vary with
each application, each must be analyzed to determine proper filtration to maintain the
required cleanliness level.

DESCRIPTION
SYSTEM RELIEF VALVES
Although the PV/PVT series pumps have very fast off-stroke compensator response,
system relief valves are recommended in all cases for safety considerations.
COMPENSATOR
The C and F pressure compensator control allows the pump to deliver full volume from
the outlet port until the pressure rises to the value set by the control. One turn clockwise
of the pressure compensator adjusting screw represents a pressure increase of
approximately 650 psi (45 bar).
The control then reduces the pump volume to that required by the system while maintaining
the preset pressure at the outlet port. The stroking piston is controlled by a 3-
way valve which is shifted by discharge pressure.
The fast response (typically 50 ms off-stroke and 120 ms on-stroke) and high flow
capacity of this valve holds pressure overshoot and undershoot to a minimum.
An adjusting screw complete with locknut allows the pump volume to be set between
maximum and zero.
Clockwise rotation pumps have the pressure compensator control located on the left
side of the pump body; on counter clockwise rotation pumps the control is on the right
side.
Units with C- compensator, a 30-50 psi (2-3 bar) check valve is recommended in the
discharge port on all open loop pumps. The check valve must be located approximately
12 in. (0.3 M) from the discharge port. Failure to locate the check valve at this point
may result in compensator hunting.

F- VENTABLE COMPENSATOR
The F- compensator is used in applications requiring remote control pressure. The
remote relief is connected to the vent port. The pressure may be controlled at any
level below the compensator pressure setting. The vent port may also be used to
remotely vent-off the compensator for starting.
Caution: The F- and L- differential spring is the same as the C- compensator spring.
Therefore it is possible to set the differential pressure too high.

DESCRIPTION
L- LOAD SENSING COMPENSATOR
The L- compensator is used for load sensing circuits. The L- compensator prevents
pilot flow from entering the circuit which will eliminate creeping of the load. The L-
compensator will let the pump deliver a constant flow rate to the circuit by providing an
adjustable D P across the customers orifice or valve. The pump will operate at 250-400
psi (17-28 bar) above load pressure.

J- TORQUE LIMITER (low range)
K- TORQUE LIMITER (high range)
The torque limiter monitors both pressure and displacement (hanger angle). It is a sina
load sensing or remote venting circuit. As pressure rises, flow is reduced according
gle spring unit which works with the F “ ” compensator, and can also be connected into
to the zero adjustment and spring rate of the torque limiter. When pressure has risen
to its full value, control is assumed by the“F”compensator . The torque limiter func-
tions down to 20% of corner power. Lower adjustment are possible, at the expense of
peak pressure.
