- Oversized, separate suction and pressure circuits create a smooth flow of the liquid product with no pressure loss.
- Convenient visual oil tank fitted with matched diaphragm to ensure correct oil level.
- Check valves can be serviced easily, minimum maintenance.
- Crankshaft stroke reduced, which increases diaphragm life because diaphragms are not stressed.
- Unique pulsation damper system provides dampening on 32 circuits instead of one, which reduces vibrations and allows for smoother operation.
- Four diaphragm material options are available, contact factory.
- Special check valve design: unique spherical shaped poppet and conical seat made of 316 stainless steel, delivering high volumetric efficiencies.
- Pre-set diaphragm bolt and diaphragm washer are made from 316 stainless steel. This exclusive feature ensures chemical resistance and longer life of the pump.
