General Install Information

Fluid recommendations
Premium quality hydraulic mineral oil fluids are recommend, like H-LP oils to DIN 51524, part 2.
The viscosity range should be 25 to 50 mm2/s (cSt) at 50 0C.

Normal operating viscosity range between 12 and 100mm2/s (cSt).
Maximum start-up viscositiy is 800 mm2/s(cSt). Operating temperature -30 to + 70 0C.
For other fluids such as phosphoric acid esters or for
other operating conditions consult your Parker representative for assistance.

Seals
NBR (nitrile) seals are use for operation with hydraulic fluids based on mineral oil.
For synthetic fluids, as perhaps phosphoric acid esters, Fluorocarbon seals are
required.
Consult your Parker representative for assistance.

Drain line
The drain line must lead directly to the reservoir without restriction.
The drain line must not connect to any other return line.
The end of the drain line must be below the lowest fluid level in the reservoir and as far away as possible from the pump inlet line.
This ensures that the pump does not empty itself when not in operation and that hot aireat oil will not recirculat.

For the same reason, when the pump is mount inside the reservoir, the drain line should arrang in such a way that a siphon is created.

This ensures that the pump always fill with fluid.
The drain pressure must not exceed 2 bar.
Drain line length should not exceed 2 metres.
Minimum diameter should select according
to the port size and a straight low pressure fitting with
maximised bore should use.

Filtration
For maximum pump and system component functionability
and life, the system should be protected from contamination by effective filtration.
Fluid cleanliness should be in accordance with ISO
classification ISO 4406:1999. The quality of filter elements should be in accordance with ISO standards.
Minimum requirement for filtration rate x (mm):
General hydraulic systems for satisfactory operation:
Class 20/18/15, to ISO 4406:1999
Hydraulic systems with maximised component life and
functionability:
Class 18/16/13, to ISO 4406:1999
It is recommended to use return line or pressure filters.
Parker Filter Division offers a wide range of these filters
for all common applications and mounting styles. The use
of suction filters should be avoided, especially with fast
response pumps. Bypass filtration is a good choice for
best filter efficiency.

Installation and mounting
Horizontal mounting: Outlet port side or top. Inlet port side
or bottom, drain port always uppermost.
Vertical mounting: Shaft pointing upwards.
Install pump and suction line in such a way that the
maximum inlet pressure never exceeds 0.8 bar absolute.
The inlet line should be as short and as straight as
possible. A short suction line cut to 450
is recommended
when the pump is mounted inside the reservoir, to improve the inlet conditions. All connections to be leak-free,
as air in the suction line will cause cavitation, noise, and
damage to the pump.

Drain port
Compensation may cause short-term (20 to 30 ms) flow
increase, e.g. 30 l/min (PV 016 to 023), 40 l/min (PV 032
to 046), 60 l/min (PV 063 to 092),80 l/min (PV 140 to 180)
and/or 120 l/min (PV270). Please consider for dimensioning.
Shaft rotation and alignment
Pump and motor shafts must be aligned within 0.25mm
T.I.R. maximum. A floating coupling must be used.
Bellhousings and couplings can be ordered at manufacturers listed in this catalogue. Please follow the coupling
manufacturer’s installation instructions. Consult your
Parker representative for assistance on radial load type
drives.

Start up
Prior to start up, the pump case must be filled with
hydraulic fluid (use case drain port). Initial start up should
be at zero pressure with an open circuit to enable the
pump to prime. Pressure should only be increased once
the pump has been fully primed.
Attention: Check motor rotation direction.
