Air Operated Diaphragm Pumps and Sump Pumps

Rhino Lifting Maintenance (Pty) Ltd are proud to be associated with Ingersoll Rand as a certified South African Distributor for their range of air operated ARO diaphragm pumps.

Features to save you money. ARO Air Operated Diaphragm Pumps do: -

  • Easily pump from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage. 

  • Be used in potentially explosive areas. Most of the ARO Diaphragm Pumps are ATEX certified (CE Ex11 2GD X). 

  • Self prime in excess of 8 metres with water.

  • Operate dry without damage. The pump stops if the discharge is closed or at pressure.

  • Have the flow adjusted from as little as 1 litre per minute to full flow with just a regulator or needle valve on the air supply.

  • Offer many materials of construction compatible for the Chemical Industry: 

    • ​Offer aluminium, cast iron, stainless steel and Hastelloy on our range of metallic pumps. 

    • Offer polypropylene, Acetal and PDVF on our range of non-metallic pumps.

  • ​Supply convoluted Diaphragms which ensure long life and reduced maintenance.

  • Offer the patented “Unstallable” unbalanced air valve design which avoids stalling issues associated with other pumps. 

  • Offer the “Quick-Dump” exhaust valves which divert cold exhaust air from ice-prone components, preventing freezing. 

This is the most reliable pump line on the market.

Piston Pump Types and Applications


  • Transfer applications: Involves moving a low-to-medium viscosity fluid using 2-ball and 4-ball piston pumps.

  • Extrusion applications: Involves using a Piston Pump to apply medium -to- high viscosity materials, using Chop-Check and 2-ball piston pumps.

  • Coating Application: Involves application of a material by either spray or dipping using 2-ball and 4-ball pumps. 

Rhino Lifting Maintenance (Pty) Ltd offers full service and spares support to ensure your pumps are always operating at peak performance.
