Sumitomo QT62-125F-BP-Z Hydraulic Pump - 125cm³/rev - 4550 PSI - 2020

Sumitomo QT62-125F-BP-Z High-Pressure Internal Gear Pump | 2020 | S/N 20D00009

The Sumitomo QT62-125F-BP-Z is a premium, high-performance internal gear pump designed for extreme industrial environments requiring high pressure and near-silent operation. Engineered with a multi-stage gear configuration, this pump delivers exceptional pressure stability (up to 4,550 PSI) while maintaining a pulsation rate as low as 0.02 MPa.

This 2020 unit (S/N 20D00009) is a "125" displacement model, capable of 125 cm³/rev. It is a preferred component for high-duty cycle applications such as CNC lathes, injection molding machines, and heavy-duty hydraulic presses. Known for its "back-pull-out" serviceability and ability to handle low-lubricity fluids, the Sumitomo QT series is the gold standard for long-term reliability in the hydraulic industry.
