Stall-free design

Available from UK distributor AMS Pumps is a range of AOD® air operated diaphragm pumps from Price Pump with flow rates to 50m3/h.

Features include a stall-free design. The 'Posi- Shift' tandem spooled air distribution valve ensures reliable operation in all types of low pressure and start/stop applications. Fewer parts and no O-rings result in easier maintenance.

There are no metal-to-metal wearing surfaces and the oil-less design means no oil mist in the environment and no oil, grease or lubricants to contaminate products.

Quiet in operation, the air-valve is reported to have operated trouble-free since its introduction 20 years ago.
