High Volume Rotary Vane Drum Pump with Filter

Specifications

Operating instructions

1. Oil Gears Before Use
Before using the 5080AN high volume rotary refuelling pump, make sure that you fill the gear cover with oil. Fill with SAE 30 oil or equivalent to the reference line through the lubrication bolt hole (as indicated on the diagram). Inspect periodically.

2. Revolution Direction
The handle turns in a clockwise direction and the pump discharges one litre per one revolution of the handle.

3. Filter
A filter of #60 mesh polyethylene net is supplied as standard on the pump and is located at the bottom of the suction pipe. Rotating the handle and therefore operating the pump may become harder if the filter is clogged with impurities that may have been filtered out of the fuel or low viscosity oil. It is recommended that you remove the filter periodically and clean it with kerosene.

4. Cautions

• Suitable liquids include most low viscosity liquids such as diesel, unleaded petrol, kerosene and low viscosity oils. Although the pump can be used to pump other liquids of high viscosity, the pump becomes harder to operate and doing so will shorten the life of the pump & may void the warranty. 
• Do not use this pump for any solvent or chemical transfer as these liquids will dissolve the Buna N seals and gaskets, etc. (Use the 301-A, 401-A, 733 or 933 for solvents).
• Please note when pumping fuels like kerosene, petrol or diesel, these products tend to “dry out” the internals of the pump causing parts “to stick” and the pump not to prime and dispense. To stop this from happening and to increase the working life of your pump, we recommend that you lubricate the gears of the pump by dropping a few drops of oil into the pump body by taking off suction pipe (2000-42) & lubricating at this opening. After undertaking lubrication of the pump in such a manner, please rotate the handle a few times. 
• Do not pump liquids containing dirt or particles such as waste oil. Strained liquids may block the filter, preventing discharge, which can damage the pump interior or cause other problems.
