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

Refined Fuels
Refined fuels would include petroleum based fuel oils and some Jet Fuels. Their viscosity and temperature handled can vary greatly. Normally these are handled in bulk transfer operations.

Biofuels
Biofuels include Biodiesel and Ethanol. These are fuels made from renewable resources and typically blended with refined fuels as additives.

Glycol (Ethylene Glycol, Ethylene Alcohol)
A clear, colorless, syrupy liquid used in a variety of applications involving lacquers, resins, printing inks, adhesives, waxes, and pharmaceuticals. It is often blended with water and used as a coolant and anti-freezing agent.
