Pneumatic Oil Pump 3:1 Operating Instructions
1.4 Recommended Applications
This pump was developed for pumping diesel, motor, and hydraulic oil as well as low-viscosity and
selflubricating mediums. The pump is recommendable for use in pipe systems together with a
hose reel. Evenwith a 15 m hose, delivery meter and anti-drip nozzle, the pump still has a very
high delivery performance. The delivery performance is dependent uopn the viscosity of the oil,
the temperature as well as the length and the cross-section of the piping. The pump will also
operate in non-vertical installations.
1.5 Operational Area Requirements
The operator of such an installation is, according to § 19i WHG (Germany) responsible for
continuous monitoring to ensure compliance with the above stated requirements at the installation.
The oil pump is intended for use within a building. The installation area must be selected such that
correct operation is ensured.
To avoid unnecessary damage and to prolong the life expectancy of the pump we recommend
that an air line combination filter, regulator and lubricator is utilised to ensure that the compressed
air supply is not contaminated and is regulated at the recommended pressure.
New installation lines should be cleaned to avoid any residual metal filings damaging individual
components within the pump. When changing containers protect the suction tube properly to
make sure that the suction tube will not be contaminated by dirt particles, such as metal parts,
splinters etc. which will additionally contaminate the lubricant in a new container.
To make service and maintaining work easier we recommend the installation of a lever ball valve
placed between the oil connecting hose and the fixed oil distribution pipe work.
Um Reparaturen oder Servicearbeiten leichter durchführen zu können, empfehlen wir einen
Kugelhahn zwischen Druckschlauch und Öldruckleitung zu montieren.
2. General Safety Advice
2.1 Safe Working Advice
• The oil pump has been designed and manufactured according to the health and safety
requirements of the relevant EC guidelines.
• Nevertheless, there can still be risks if the product is not set up or operated as stipulated.
• Therefore, before using the oil pump, read these operating instructions and pass them on to
other users of the pump.
• When operating the oil pump, the local safety and accident prevention rules and regulations
always apply, as well as the safety advice in the operating instructions.
• Only approved PRESSOL maintenance personnel should open or repair pumps within the
guarantee period.
WARNING! The compressed air line must be disconnected and the discharge pistol actuated to
ensure so the pump is depressurised before the pump unit is opened or inspected. For safety
reasons the compressed air line should be disconnected when the pump is not in use otherwi se
the pump will remain pressurised.

2.2 Risks when Working with the Oil Pump
Warning!
Never work on a pump that is running!
Mount or remove attachments and accessories only when the pump is switched off.
Warning!
Do not pump contaminated fluids!
Take special care to ensure that there is no contaminant in the fluid to be pumped.
Install a strainer on the suction pipe.
Warning!
Damaged attachments and accessories can lead to personal injury and material damage!
Suction and pressure pipes must not be kinked, twisted or stretched.
The pressure-side installation of an overflow valve is recommended (see accessorie s).
Attachments and accessories must be checked for wear, splits or other damage at all times.
Damaged attachments and accessories must be replaced immediately.
With reference to the period of use, please note the details in ZH 1/A45.4.2 or DIN 20066
Part 5.3.2.
Caution!
Spilled fuel can result in environmental damage
Local and country rules and regulations relating to domestic water supplies and fuel storage
must be obeyed.
3. Assembly
• The oilpump can be used for oil supply out of original drums or out of oil storage tanks.
Note
An upward installation of the suction line is recommended according to European regulation.
Consider before assembly the height of the container used and in case of necessity the use of an
oil container storage unit..
3.1 Barrel- and Tank Mounting
• Fix pump and suction tube using the G 2“ drum retention adapter on the container or on the
storage tank.
• Connect the discharge hose to the pump connecting adapter G ½“.
• Connect the discharge valve or the manual flow meter to the discharge hose.

3.2 Wall Mounting
Note
When installing the 3:1 oil pump in connection with long distribution lines we recommend the use
of a foot valve
To avoid possible overpressures in the pump we recommend in any case the installation of a foot
valve with an overpressure releasing drill hole (art.no. 03337).
• For fixation of the oil pump we require 2 screws with a diameter of 10 or 12 mm (not included in
the product packageChoose screws corresponding to the wall material, on which the pump
shall be mounted.
• Take care for a stabil wall mounting of the pump. Take care for a protected mounting location,
protecting i.e. against splash water,
• Please mount the calibratable pump for a trouble-free operation of the integral air elimator in an
upright position, only.
• Fix suction tube using the G 2“ drum retention adapter on the container or on the storage tank.
• Connect suction tube and pump with suction hose (hose connection G ¾“)
• The air- and oil back-flow tube of the calibratable pump version shall be lead back into the
container or tank utilizing the drilled hole in the drum adapter.
• Connect oil pump with control valve or manual flow meter and oil discharge pipe work with a
discharge hose.
• Installation material for discharge pipe work
• Length of discharge pipe work up to 15 m: Pipe work tube DN 20 (R ¾“) DIN 2448 or
bigger; St 37 acc. to DIN 1629.
• Length of discharge pipe work exceeding 15 m: Pipe work tube DN 32 (R 1 ¼“) DIN 2448
or bigger; St 37 acc. to DIN 1629.
• Overflow valve (see accessories).
• Lever ball valve (see accessories).
Note
Pay attention to a correct installation ad to a accurate connection of the accessories with the
pump
Use suitable sealing material in any case. (i.e. Teflon-tape).
• The pump is now ready for operation.

4. Preparing for Operation
4.1 Venting the Pump and Installation
• Connect Pump with compressed air ( 6 bar recommended)
• Open the farthest control valve of the installation supported by a oil collecting tray until oil will
be discharged completely air-less.
• Repeat this procedure on any point of discharge of the installation.
5. Operation
Note
To ensure that the tank can be completely emptied, the suction hose must reach to the bottom of
the tank.
Caution!
Never operate the pump without delivery fluid. There is a danger of your oil pump being damaged
if operated dry.
Caution!
Shut-off the compressed air line, when the oil supply system is not needed for a longer time in
any case.
• Start the pump with compressed air, the oil supply system is ready for operation.
• The pump switches on and starts to discharge when opening the control valve.
• When closing the control valve the pressure in the oil system will increase forcing the pump to
come to a stillstand.
5.1 Changing a Barrel
• You can avoid contamination by inserting the suction line directly into the new oil container.
6. Maintenance
The muffler and air inlet filter should be cleaned regularly to maintain the trouble free performance
of the pump. If an air line lubricator has not been installed frequently lubricate the pump by
inserting 2 to 3 drops of quality oil through the air inlet connector at regular intervals.
The oil pump is very easy to maintain and service.
Due to the operator responsibilities according to § 19i WHG (German rules), the following
components must be regularly checked and replaced as necessary, to minimise the possibility of
environmental or equipment damage, or personal injury:
