1. (EN) Generic

The air operated pump has two main parts. One double acting air motor driving a double acting liquid pump.
The fluid is sucked into the pump through the bottom valve when the piston is on the upward stroke. The fluid is
discharged in both up- and downs strokes. The relationship between then area of the air piston and area of the pump
decides the pressure ratio. The pressure ratio is 4:1 and the theoretical pressure when the pump has stopped is 4
times higher than the air pressure. The exhaust air is blown out through a silencer made of sintered brass. All parts
in contact with fluid are made of stainless steel (ISO 2346 and similar). The central bar is nickel-plated. All seals in
contact with fluid are manufactured of PTFE (Teflon®) or FKM (Viton®).

Important! Do not operate the pump without fluid present. Running the pump dry could

damage the seals and generate heat. Damaged seals can cause fluid leakage and
together with heat cause explosive vapors if a flamable liquid is pumped.

For this reason it is recommended to prime the pump with fluid before starting
it and run at low air pressure until the pump is full. It is always recommended
to use some dry pumping protection and if a flammable liquid is to be pumped
it is required.

1.1. Safety precautions

• The pump is to be used with water based fluids like windscreen liquid, glycol/water mixture and non-lubricant fluids

like kerosene, white spirit, lacquer solvent and similar with a ignition point of 100°C or above.

• When used for flammable liquids make sure that the marked ground screw properly grounds the pump before starting
it, see picture on page 4.

• The pump is not suitable for acids or salt water.

• Check that all accessories and components are suitable for the distributed fluid and the working pressure of the

system.

• The system must be tested to 1.3 times the working pressure before being put into operation.

• Do not exceed the maximum air pressure of the pump, 1.0 MPa.

• Close and disconnect the air supply and relieve the liquid pressure in the system before any work to the pump or

system is carried out

• Only use genuine manufacturers spare parts. Never use worn or damaged spare parts.

• Do not direct outlet valves or any other dispensing valve against the body or any other person as the liquid can

penetrate the skin or damage the eyes.

• Do not use a higher air pressure than needed to get the needed system performance.

• Always turn off the air pressure to the pump when the premises are unattended.

2. (EN) Installation

2.1. Generic

Remove the protective caps from the pump, including plugs from the air inlet and the fluid outlet.
Remove the drum adapter from the pump tube. Mount the adapter into the 2” hole in the pump or pump

bracket. If the pump is to be used with a drum of similar the suction tube, 222 62 14, has to be fitted. Do not
use PTFE (Teflon®) tape to seal any thread. Use Loctite® or similar liquid sealant for tubing system.

Put the pump vertically into the drum and lock the pump so that the outlet is in the desired position. Set the
pump with a bottom clearance of 10-15mm and lock the pump into place using the adapter.

Connect the liquid outlet hose to the outlet of the pump and the air coupler to the air inlet.
Do not mount a pump directly onto a sheet metal wall or similar construction, which can create noise

resonance and augment the normal noise level of the pump.
A hose must be mounted between the outlet of the pump and the fixed pipe work. This hose should have

sufficient length to make it possible to lift the pump in and out of the drum or tank without difficulty.
Do not let the pump run fast when starting up a new system or after changing barrel in an existing system.

Start the pump with lowered air pressure on initial priming and gradually increase the pressure, as the system
is primed.

Important! If the air pressure in the system is higher than the working pressure of the

pump it will be necessary to install an air regulator and gauge into the airline
prior to the pump.

Important! The pump is pre-lubricated with silicon grease. It is not necessary to use a

lubricator during normal operation. If a lubricator has been used with the
pump, the pre-lubricated silicon grease will have been washed away. It is
therefore needed to continue the use of lubricator.

2.2. When pumping flammable liquids

Besides the above mentioned, please also note the
following when pumping flammable fluids.

• The pump must be grounded by the dedicated ground screw,
see picture.

• The pump must be equipped with dry-pumping protection.

• At first start up the pump and the system it is connected to

must be thoroughly checked for leaks.

• During operation the pump and the system it is connected to
must be checked for leaks on a regularly basis.

3. (EN) Maintenance

Empty and clean the air filter. If a lubricator is installed it should always be filled with air tool oil or similar. Mineral
based motor oil, SAE 10, can also be used, Synthetic oil or other oils must not be used. Check for possible leakage
in the connections or couplers. Keep the fluid and equipment clean and free from dirt. When changing drum, make
sure the pump tube and bottom valve are kept off the floor.

4. (EN) Service

Avoid damaging seals and all moving surfaces. When servicing the pump, all parts should be protected from dirt,
especially the cylinder and central bar. Keep the working area and tools clean. Clean and grease all surfaces with
silicon grease or similar, especially all O-rings and moving surfaces. Use kerosene or similar liquid for cleaning the
air motor parts.

4.1. Air motor

Fasten the outlet housing of the pump into a vice in a vertical position. Loosen the four screws in the lid.
Remove the lid. Air supply nipple (Pos 2) is sealed by two O-rings in the valve mechanism. To inspect the air
filter u carefully thread a screw, M6 or W¼”, between ½ and 1 turn inside the filter. Pull up and clean or
change it. Loosen the silencer’s (Pos 25) four screws (Pos 28) and remove the protective cover (Pos27).
Unscrew the six screws (Pos26), which keep the mechanism (Pos 1) in place. It is now possible to inspect
and replace the valve mechanism or replace the valve spool kit (Pos 24). To inspect the air motor cylinder,
loosen the four lower screws (Pos 29). Pull the air motor off the piston. Change all damaged and worn parts
and Reassemble in reverse order.

Important! Lubricate all parts and seals in the air motor before reassembly with Silicone

grease. No other grease should be used.

4.2. Exchange of seals in outlet body

Fasten he lower part of the air motor into a vice with pump tube in horizontal position. Loosen the four lower
screws (Pos 29) and pull off the air motor with the complete valve mechanism. Release the piston (Pos 5)
from the central bar (Pos 15). Disassemble the entire fluid part by releasing the lock nut seal screw (Pos 11)
and unscrew the complete “wet” part. It is now possible to inspect the upper seal (Pos 7). Fasten the stainless
outlet body into a vice. Unscrew the pump tube (Pos 20). Pull the central bar (Pos 15) out through the Teflon
seal kit (Pos 12). Inspect all working surfaces and replace all worn or damaged parts. Be very careful when
handling the PTFE (Teflon®) seals, they are very easy to damage.

4.3. Pump mechanism

First carry out the first 2 steps in “Exchange of seals in outlet body”, see above. Fasten the stainless outlet
body into a vice. Unscrew the pump tube (Pos 20). Pull the central bar (Pos 15) out through the PTFE
(Teflon®) seal kit (Pos 12). Inspect the piston (Pos 19) and replace the seal (Pos 23) if necessary. Be careful
to avoid any dirt getting in and around the piston assembly. Replace all parts that are worn or damaged. If
you suspect dirt in the bottom valve (Pos 21) unscrew it for inspection. If the bottom valve is removed the O­ring (Pos 22) must be replaced. If the pump tube is removed from the outlet body the O-ring (Pos 16) must be
replaced. Do not over tighten the bottom valve or pump tube when reassembling. The O-rings will seal
against leakage.
