This 1-1/2 inch double diaphragm paint pump is engineered for handling diesel, grease, kerosene, and various oils. The pneumatic-powered pump delivers reliable performance with smooth operation and minimal maintenance requirements.

1. Ensure the mounting surface can support the pump weight, hoses, and accessories, plus operational stress
2. Securely fasten the pump using bolts on the mounting feet during installation
3. Allow adequate maintenance space around the pump for easy operation and servicing
4. Use rubber padding while fastening to reduce noise and vibration during operation

• Multiple port options for enhanced installation flexibility
• Modular air valve design ensures stall-free, low-pulsation operation with smooth changeover
• Extended diaphragm life - up to 5x longer than standard models for reduced maintenance
• Four-bolt joint design provides even sealing pressure for optimal performance

The RV series air diaphragm pump operates using two flexible diaphragms mounted in symmetrical chambers connected by a link rod. Compressed air enters through the inlet terminal, driving the diaphragms and link rod in synchronized motion while expelling air from the opposite chamber. The air-distributing valve automatically guides compressed air to alternate chambers when the piston reaches the end of each stroke.

• Threaded connection: Plastic air diaphragm pumps from 1/4" to 1-1/2", and all metal pumps
• Flanged connection: Plastic air diaphragm pump from 1/2" to 3"
