    The SANDPIPER G20 ball valve pump is CSA and Blue Star (ANSI LC6)/Blue Flame (Canadian Technical Letter R-14) certified and meets the demands of a wide variety of oil and gas applications. Decades of innovation and engineering expertise are behind this pump line, which has the most rigorous certifications for safety and reliability in the double-diaphragm pump industry.

    Performance and Reliability

    • Hydrostatic strength test: 500 psi (34.5 bar)
    • Temperature limits: -10°F (-23°C) to 180°F (82°C)
    • Nitrile or FKM elastomers: air/gas end options for varying temperatures and chemical compatibility
    • Externally serviceable air distribution system: allows for quick and easy access to the main air drive components without disassembly of the entire pump and/or removing it from service
    • All-bolted construction: ensures sealing forces are applied evenly across the pump for leak-free operation
    • Robust diaphragm connecting rod: guaranteed not to bend or break; assures reliable and consistent diaphragm operation
    • Large flow area: reduces fluid velocity through pump, which often lessens wear
    • Thick manifold and chamber walls: greater wear resistance when pumping solids and solids-laden slurries, providing extended service life
