The 126A Series™ internal gear pump is 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 & Benefits
- Positive displacement internal gear pumping principle handles a broad range of viscosities with constant flow rate
- Axial rotor thrust is controlled by double row ball bearing or tapered roller bearings; a bushing provides a secondary point of radial shaft support
- Rotatable bearing housing provides easy rotor end clearance adjustment for viscosity or to compensate wear

Crude Oils
This is a very generic term for unrefined oils typically being recovered from the ground. Some crude oil may contain particulates from the oil well or recovery method. They are considered to be flammable liquids. Crude oils are later refined and used for everything from making plastics to gasoline.
