Isochem Series GMC6

up to 10 gpm (45.46 lpm)
up to 100 psig (6.90 bar)
up to 450°F (232°C)

Isochem Gear Pumps have numerous material combinations available which makes them ideal for continuous duty industrial application over wide temperature, viscosity, and pressure variations. These pumps yield a constant volume for a particular drive speed and provide linear pulsation-free flows. They depend only upon fluids pumped for cooling, and are designed with component materials which are inherently self-lubricating.
