Installation

Lifting
Caution Risk of bodily injury. To prevent bodily injury
when lifting the pump, ensure correct lifting tech-
nique is used. Make sure that all lifting devices are working
properly and that they are approved for the weight of the
pump. Use lifting straps under the pump unit to prevent
bodily injury.
Mounting
Precaution Risk of bodily injury. Make sure that all
parts of the pump are firmly secured.
An upright position of the QPM3 pump, standing on the
electric motor feet is recommended.
The pump can be mounted in any position in steps of 90°
in relation to the electric motor.
To achieve optimum pump capacity, install the unit below
tank oil level (max. 5 meter) and as close to the tank as
possible. When installed above tank oil level, minimize the
difference in height and install a check valve or shut-off valve
at the pump inlet. Place the unit to ensure adequate air flow
through the electric motor.
The acoustic pressure level could reach 65-67 dB(A) LpA
at a distance of 1 m under normal conditions. Inappropriate
location or operation under extreme conditions could gener-
ate increased acoustic power level.
Oil connection
Connect the QPM3 low pressure pump using flexible hydraulic
hoses. Make sure that all connections and hoses are sized
according to the system pressure, flow, temperature and type
of oil. Connect the hydraulic hoses as illustrated in Figure 2.
A – Inlet.
B – Outlet.
Maximum permitted oil temperature is 100 °C.
The size of the inlet line should not be inferior to the
pump connection size. A larger size is recommended.
Avoid flow rates in excess of 1 m/s in the pump inlet line.
Maximum pressure on the pump suction side is 0.5 bar.
Maximum suction pressure in the pump inlet line with oil
filled pump is 0.4 bar.
Installation and servicing manual | English
OLAER/OA-Technik will not be held responsible for the
consequences of any modification or variation with regard
to connections.
Electrical connection
Danger Electrical shock hazard. All electrical connec–
tions must be made by a qualified electrician!
Prior to connecting the motor to the electrical supply system,
make sure that the specification on the electric motor rating
plate corresponds to the mains supply voltage and frequency.
The electric motor should be installed according to general
rules and electrical safety regulations and must be installed
by a qualified electrician.
Caution Risk of personal injury and damage to prop-
erty. Be careful when connecting the equipment.
Improperly made connections, damaged cables, etc. could
cause parts to become current carrying or result in incorrect
direction of rotation of the electric motor and pump.
See Figure 3.
Important Do not exceed the maximum rated current for
the electric motor, see electric motor rating plate.
Note! An electric motor overload protection is recommended.
In extremely humid environments, especially when the
operation is intermittent, condensation may form. Some
motors are fitted with plugged holes, which can be used to
drain condensed water. Depending on the placement of the
electric motor, proper plugs should be removed.
If the QPM3 low pressure pump is installed in an environ-
ment where water may penetrate into the electric motor, use
a protective shield. The protective shield is available as an
option.

Handling

Prior to initial start-up
Precaution Make sure that the unit is securely fixed
and correctly connected. We recommend to run the
pump with the same oil as used in the hydraulic system. See
Technical specification for oil compatibility.
Note! Air in the inlet line could sometimes cause problems
at initial start-up. Make sure that the pump inlet is always
filled with oil.
Prior to start-up
Precaution Make sure that the pump can be put into
service without causing bodily injury or damage to
property or environment.
Make sure that:
• all hydraulic connections are tight,
• valves and similar throttling devices are open and
that conduits and couplings are not damaged.
