ECO® Gearchem pumps offer the reliability you need to safely handle clear lubricating and non-lubricating liquids. Extensive material availability provides versatility for pumping low or high viscosity fluids over a broad range of temperatures, pressures, and corrosive services. Typical applications for these self-priming, external-spur gear pumps include chemical transfer, cyclic operations and continuous production systems – both open-end and closed-loop. They are well suited for pilot plants, vacuum systems and metering applications.
At the heart of each ECO® Gearchem pump are two tightly toleranced, machine- generated spur gears consisting of a drive and an idler gear. Self-priming capability is accomplished by our closely toleranced gears which evacuate air from the suction piping. Gearchem pumps provide linear, pulsation-free flows. And the pumps are bidirectional. This lets you easily change flow direction.
Six models available with a maximum capacity of 60 USGPM (13.6 m 3 /h). Most models offer maximum differential pressure of 100 psi (6.9 bar). ECO® pumps are designed for temperatures ranging from -100 F to +450 F (-73 C to +232 C). Gearchem pumps are ideal for vacuum applications where system pressures are as low as 0.1 mm Hg abs.
