Graco
Model: 660050
The Husky 3250 air-operated double diaphragm pump is equipped with a stall-free, low-pulsation air valve for smooth and rapid changeovers. Its one-piece center section design minimizes leaks and reduces maintenance compared to other diaphragm pumps.
This 3-inch pump is designed for high-flow transfer applications, capable of handling up to 250 gpm, including viscous materials.
- The four-bolt joint design ensures uniform sealing pressure for leak-free operation.
- Features a stall-resistant modular air valve for efficient operation and quick replacement.
- The pilot valve is externally serviceable and spring-loaded for fast changeovers.
- The Graco air valve uses up to 30% less energy and can be externally serviced in approximately 5 minutes.
- The air valve requires no lubrication, eliminating the need for oilers.
