ARO PD30

3″ Aluminium/Santoprene metallic diaphragm pump

Features
The Ultimate in heavy duty pump design.
The best of any diaphragm pump on the market today.
Up to 4 times the life of traditional diaphragm pumps due to the EXP’s new convoluted diaphragm design.
Efficiency – Simul-Shift™ valve provides ultra-positive, reliable shift signal
Reliability – ARO’s patented ‘Unbalanced’ air valve ensures no-stall operation
Versatility – Broad range in materials of construction for optimum fluid compatibility
Environmentally Sound – Bolted construction for leak-free fluid handling
Serviceability – Easier service through modular design

Air operated Diaphragm Pumps are designed for general use. They can easily pump from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage. Due to their pneumatic motor, they can be used in potentially explosive areas. Most of the ARO Diaphragm Pumps are ATEX certified (CE Ex11 2GD X). They are also self-priming up to an elevation of 8.3 m (with water) and can operate dry without any damage. If the event the fluid outlet is closed, the pump stops. It restarts with the reopening of the fluid circuit; no pressure relief valve or bypass is necessary.
These pumps offer the ability to vary the flow outlet and discharge pressure as slow as one litre per minute up to 1040 litres per minute for our larger sizes and adjust fluid pressure up to 8.5 bar, with just using an air filter/regulator and a needle valve.
The Aro range of Diaphragm Pumps offers many materials of construction compatible for the Chemical Industry: Our metallic offering consists of aluminium, cast iron, stainless steel and Hastelloy. Our Non-metallic offering consists of polypropylene, Acetal and PDVF. All ARO pumps are available with Convoluted Diaphragms offering long lasting life and reduced maintenance.
