How does the high-pressure gear pump perform under high-temperature and high-pressure conditions in metallurgy, die-casting, and similar applications?

The high-pressure gear pump uses a high-grade aluminum alloy body and is equipped with oil-less bearings and Viton oil seals. It can operate normally in both forward and reverse directions under high temperatures and pressures without leakage, offering superior high-temperature resistance.

In a hydraulic system, how does the high-pressure gear pump ensure flow stability?

The high-pressure gear pump employs a dual-pump collaborative design, integrating two independent pump bodies. This allows it to simultaneously provide stable flow to multiple hydraulic circuits, optimizing system efficiency and ensuring uniform, continuous fluid delivery, adapting to the precise control needs of multi-circuit hydraulic systems.

How does the industrial gear pump ensure stability and service life in high-pressure environments?

Our gear pumps feature an oil-less bearing structure design, ensuring stable operation at pressures above 210 bar. This design also maintains internal lubrication within the pump, guaranteeing minimal wear and a longer service life.
