Gorman-Rupp 14250-007-X116-T08 BEL-O-JUST Bellows Metering Pump
The Gorman-Rupp 14250-007-X116-T08 is a compact, self-contained bellows metering pump built for applications that demand precise, repeatable fluid dosing without the wear and leak points of traditional dynamic seals. At its core is a 1-inch Viton (FKM) bellows that flexes to move fluid, paired with Viton o-rings throughout the wetted path, giving the pump strong resistance to a wide range of aggressive chemicals and process fluids. Because the bellows design eliminates packing glands and dynamic seals, the pump can run dry without damage and self-primes on startup, which makes it a dependable choice for intermittent or unattended dosing duty.
Power comes from a 115-volt, continuous-duty shaded-pole gearmotor turning at 60 RPM, rated for a minimum of 2,000 hours of service life. The stroke is fully adjustable from 10% to 100% of full travel, letting an operator dial in flow with accuracy of about ±0.5% from stroke to stroke once the pump is set between 50% and 100% of full stroke. Built-in poppet check valves prevent backflow on the discharge side, keeping dosing consistent even as line pressure fluctuates.
This particular configuration, the X116-T08 variant, pairs the standard BEL-O-JUST bellows and motor assembly with a specific motor/drive and tube-connector port arrangement, making it easy to drop into existing tubing runs. It's rated for fluids up to 140°F and viscosities as high as 5,000 centistokes, and it's equally at home dosing detergents on a production line, feeding chemistry through a film or X-ray processor, recovering silver from spent fixer, or handling wash and rinse cycles on semiconductor wafer processing equipment.

Frequently Asked Questions
Q: What fluids is the Gorman-Rupp 14250-007-X116-T08 compatible with?
A: Because its bellows and o-rings are made from Viton (FKM), this pump handles a wide range of chemically aggressive fluids, including many acids, solvents, and process chemicals, up to a maximum temperature of 140°F and viscosities as high as 5,000 centistokes.
Q: Can this pump run without fluid present?
A: Yes. The bellows design has no dynamic seals to damage, so the 14250-007-X116-T08 can run dry and will self-prime again once fluid becomes available at the inlet.
Q: How is the flow rate adjusted on this pump?
A: Flow is set by adjusting the stroke length from 10% up to 100% of full travel, giving accurate, repeatable dosing once the stroke is set within the 50–100% range.
Q: What does the T08 designation mean on this model?
A: The T08 code identifies the specific tube-connector port configuration used for this pump's inlet and outlet fittings, distinguishing it from other port styles offered across the BEL-O-JUST bellows pump line.
Q: Is this pump suitable for continuous industrial use?
A: Yes. It's built around a continuous-duty, UL-recognized shaded-pole gearmotor rated for a minimum of 2,000 hours of service life, making it suitable for ongoing production and laboratory dosing applications.
