Product Overview
The NIHON SPEED K1P4R11A is a high-performance external hydraulic gear pump engineered by NIHON SPEED, a recognized manufacturer of precision fluid power components for industrial and mobile hydraulic systems. This unit operates on the positive displacement principle, utilizing a precision-meshed pair of hardened spur gears rotating within a close-tolerance casing to draw hydraulic fluid from the reservoir and deliver it under pressure to the circuit. The K1P4R11A is designed as a compact, direct-mount pump suitable for continuous-duty operation, offering stable flow delivery, high volumetric efficiency, and dependable performance in demanding industrial environments where consistent hydraulic power is critical.
