Arrangement outside tank.
Fill pump case with oil before start.
Do not restrict suction line.
Preferred arrangement for best suction
characteristics + low noise level operation
3.1.2 Drain line connection P2
OPTION!
Connect highest drain port with a separate line
reduced in size for purging the air out of the case
AND
secondary drain port has to be connected as
main drain line.

WARNING!
Don not combine drain lines.
Maximum continuous case pressure:
p
case
= 0,5 bar
Maximum intermittent peak case pressure:
p
case
= 2 bar
WARNING!
Don not restrict drain line.
A restricted drain line can damage the pump.

3.2.2 Drain line connection P3
OPTIONAL AIRBLEED
CONNECTION
Connect compensator drain line with the reservoir.
Keep inlet and drain line separate (hot loop).
ATTENTION!
Combination and restriction of compensator
drain line may result an back pressure.
Maximum continuous drain line pressure:
p
drain
= 2 bar
Maximum intermittent peak drain line pressure:
p
drain
= 4 bar

3.2.3 P3 pumps with drain port in the rear cover
The main benefit of this version is a continuous cooling flow through the case. Thus a better volumetric efficiency
is provided. Flow out of the drain port can be up to ~ 50 l/min and is depending on back pressure in the drain line
as well as drive speed.
Drain Port on both
sides available
Beneath the design itself pumps with inlet drain
port configuration can be identified by the last
(25
th
) digit of the order code.
If this one is D or Edrain line has to be connected
to the drain port in rearcover.
In case of U or Pthe pump still features a
compensator with drain port (see installation
manual, pages 3 and 4).
Shipping plug in
covers with drains
only
Drain line has to be connected directly to
the tank.
Max. drain line pressure:
p
drain
= 0,5 bar

4 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.
5 Hydraulic fluid
5.1 Recommended Fluids
• Normal mineral oil
• Premium hydraulic fluid / HLP oil
• Biodegradable hydraulic fluid
• Synthetic hydraulic fluid
• Fire resistant fluids
Remark:
Maximum system pressure reduced to 210 bar for water based fluids.
Bearing life time reduced to 25 % by using water based fluids.
5.2 Cleanliness level
Recommendation for maximized component life and reliability:
Class 21 / 18 / 14 according to ISO 4406
5.3 Viscosity range
Minimum viscosity for short periods: 10 mm²/s (cSt)
Normal operating viscosity: 15 – 40 mm²/s (cSt)
Maximum viscosity for short periods: 1000 mm²/s (cSt)
6 Temperature
6.1 Check hydraulic fluid specification for chemical resistance of seal material!
6.2 Check temparture range of seal material and compare with maximum system and
ambient temperature!
N– Nitrile, single shaft seal - 40°C to + 90°C
D– Nitrile, double shaft seal - 40°C to + 90°C
V– Fluorocarbon, single shaft seal - 15°C to + 150°C
T– Fluorocarbon, double shaft seal- 15°C to + 150°C
Remark:
The highest fluid temperature will be at the drain port of the pump, up to 20°C higher than in the reservoir.
