1/2" Air Operated Double Diaphragm Pump | Stainless Steel Body | PTFE Elastomers | 56 litres per min
Stainless Steel Body • PTFE Elastomers • 56 l/pm Max Flow • ½" Nominal Bore • Air Operated Pump
This air operated double diaphragm (AODD) pump offers a centre positioned inlet and outlet port which gives equal flow through each side of the pump and achieves up to 20% increased flow when compared to equivalent pump sizes of alternative designs. It is self priming, has run-dry capability and is suitable for high viscosity and high specific gravity applications.
The bolted construction design ensures more support to the full surface area of the diaphragms whilst the pump is in operation and also allows for easier maintenance on strip down and assembly of the pump.
