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

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.
•
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.
