The126A Series™ internal gear pumpis the most versatile line of internal gear pumps due to the availability of many design and other options. It can handle a broad range of viscosities with constant flow rate up to 500 GPM (114 m³/h).Features & BenefitsPositive displacement internal gear pumping principle handles a broad range of viscosities with constant flow rateAxial rotor thrust is controlled by double row ball bearing or tapered roller bearings; a bushing provides a secondary point of radial shaft supportRotatable bearing housing provides easy rotor end clearance adjustment for viscosity or to compensate wear
