Variable Displacement Oil Pump

Adaptive Oil Flow Management

Enhanced Engine Lubrication Technology with VPOP

The UCAL Variable Displacement Oil Pump (VPOP) is engineered for advanced automotive and industrial applications, delivering precise regulation of oil flow and pressure. Featuring a high volumetric gerotor pumping system and a patented dual valve assembly, the VPOP optimizes oil flow rates while minimizing power consumption, leading to reduced CO2 emissions and improved fuel economy. This unique capability allows the pump to adjust its output based on real-time system demands, enhancing efficiency and ensuring reliable lubrication for long-lasting performance.

Unlike fixed displacement pumps that provide a constant flow, the VPOP intelligently varies its displacement volume to meet operational requirements. This adaptability ensures that engines and machinery receive the optimal amount of oil at any moment, improving overall system performance, reducing power consumption by up to 25%, and extending component lifespans.
