KP0588CPSS KYB Hydraulic Gear Pump 8.8cc/rev High Pressure

Product Overview

The KP0588CPSS is a KYB (Kayaba) KP05 Series external gear pump designed for compact hydraulic power systems requiring reliable flow delivery and stable high-pressure performance. Featuring a robust cast iron housing, precision-machined gear set, and optimized bearing support structure, the pump delivers excellent volumetric efficiency and durability under demanding operating conditions.

Our replacement KP0588CPSS is manufactured to OEM dimensional standards, allowing direct interchangeability with the original KYB unit. Every pump undergoes 100% simulated operating-condition testing before shipment to ensure consistent performance and installation reliability.
