Silvan Australia Selecta Air-Power Diesel Pump

Transferring diesel fuel in many applications in the resources industry, in local government and for safe working of contractors’ equipment often requires a spark-free safety environment. The Selecta division of Silvan Australia has responded to this need with the introduction of the Air-Power Diesel Pump, which operates without the need for electrical currents.

The product is a double diaphragm, compressed air-powered, multipurpose pump that is compatible with a wide range of liquids or chemicals. When used for pumping or transferring diesel, it has a rated capacity of 60 L/min, although it can also be used to pump oils, water and the Ad Blue aqueous urea diesel fuel additive.

The pump uses Viton as the principal material within a polypropylene housing. It uses only 0.2 cm/min of compressed air at a pressure of 8 bar, or 116 psi, and could be driven from the onboard compressed air capacity of most mobile equipment items. The pump has a 0.6 cm BSP air inlet connection with a 1.9 cm BSP female connection to enable a delivery hose and nozzle gun to be fitted for delivery. With no electrical components, spark-free operation is provided.

The pump has also been coupled with a 400 L capacity Polytuff tank that is baffled, UV stabilised and fitted with a full delivery system of an auto shut-off gun with swivel and a 4 m length of delivery hose. With the aid of a span-on hose fitting, it can be powered from a vehicle or equipment item that already has an onboard compressed air supply.
