Features and Benefits:

• Stall resistant design
• Modular air motor/fluid sections.
• Pressure differential in the air chambers to alternately create suction.
• Positive fluid pressure in fluid chambers.
• Ball checks insure a positive flow of fluid.

The Balcrank UL Listed pump for pumping light viscosity fluids, offers volume delivery at low air pressures and easy self-priming. This model is designed specifically for transfer, bulk unloading or loading and diesel fueling applications. It includes a pressure relief valve (per UL Specification 79) which restricts the fluid outlet pressure to less than 50 PSI. The relief valve can be plumbed to return the bleed off fluid to the storage container.
