JS Melbourne - Products

The MELBOURNE AIR PUMP/AIR MOVER is an air (or steam) actuated unit incorporating the principles of venturi and vortex for pumping slurries and a wide range of solids. It can be used as a means for transporting product or for general clean up operations in such industries as mining, power generation, dry chemicals, cement works, shipyards, particle board manufacture, and the wood chip industry to name a few.
FEATURES OF THE MELBOURNE AIR PUMP/AIR MOVER 1. Venturi ring is housed in a robust casing which has high impact strength that provides for a long damage free life in arduous field operating environments. 2. Inlet and exit tubes are manufactured from schedule 40 pipe - not a sheet metal wrap around. 3. Nozzle rings are available in stainless steel, tool steel or Delrin. 4. A range of venturi rings provide for selection of diameter and number of venturi holes. 5. Melbourne Air Pumps have full bore clearance, no restrictions. This means that any solid matter that can freely enter the inlet tube of the pump will pass through the pump. 6. A mounting plate for earthing strap is provided.

How It Works Through a tangential inlet, compressed air is fed into a manifold from where it exits into the air pump main chamber (bore) via a ring of venturi holes drilled at compound angles. As well as the venturi effect developed in the unit’s bore, the angle of the holes induces a vortex in the outgoing air. The acceleration of the compressed air through the venturi creates a region of low pressure which induces air into the air pump bore. The induced air augments the expanding compressed air in the exit tube resulting in the flow of large volumes of free air. The MELBOURNE AIR PUMP (diagram No 1252 see below) is our biggest seller. Fitted with 350CFM tool steel nozzle. Used in power stations, steel mills, aluminium smelters for picking up steel shot, aluminium spillages, bag houses. Operates at up to 1100ºC. (eg BHP HBI Plant) Suitable for the explosives industry the MELBOURNE AIR PUMP (diagram No 1252) is a device also designed for transporting prill (amonium nitrate) from heavier bulk bags to the kettle. It requires a 2½" non-static hose unit fitted with earth connection. Units have been supplied to Orica and Dyno-Noble
