The Versa-Matic E8 3/8″ (10 mm) Bolted Plastic air-operated double diaphragm (AODD) pump combines compact dimensions with reliable fluid-transfer performance for OEM equipment, specialty chemical handling and other low-flow industrial applications.
With an adjustable flow rate up to 6.8 gpm (25.7 lpm), the E8 uses Versa-Matic’s air-valve system to provide non-stalling, non-icing and lubrication-free operation. The pump can be mounted upright, sideways or inverted, allowing it to fit into space-restricted equipment and process layouts.
The manifolds can be rotated 90 degrees to adjust the port orientation. Polypropylene and PVDF (Kynar) construction options provide corrosion resistance for a wide range of compatible industrial fluids and chemicals.
