Air Operated Diaphragm Pumps


Empire Pump’s extensive range of Air Operated Diaphragm Pumps are specifically designed for durability, performance and reliability. The product is manufactured for use with many industries including chemical, pharmaceutical, waste water, effluent treatment, metal finishing and many more. The pumps robust construction gives the ability to transfer abrasive and highly viscous solutions. Our Air Operated Diaphragm range of pumps vary in size from ¼’’ to 3’’ achieving flow rate capabilities up to 1000 l/min.

Equipment materials of construction are available in polypropylene, PVDF, aluminium and stainless steel. Our range of Air Operated Diaphragm Pumps offer technical benefits when considering the corrosive nature of the chemistries being transferred. The air valve and centre section of the pump is plastic opposed to aluminium. Non-metallic constructed parts are more corrosive resistant should chemicals reach the centre section of the pump.

Furthermore, our pump design utilises bolts opposed to band clamps, ensuing more support to the full surface area of the diaphragms whilst the pump is in operation. The bolted design also provides easier maintenance on strip down and assembly of the pump.

Our pump design offers a centre positioned inlet and outlet port, this gives equal flow through each side of the pump. This design feature enables our pump range to achieve 15 to 20% increased flow rate for the equivalent pump size of an alternative manufacturer.
