Product Overview
The Heavy Motions 423-9323-008 is a heavy-duty tandem gear pump engineered as a direct aftermarket replacement for the Permco P257B450AXZA20-00ZKCZA20-1, commonly used in Serco loader hydraulic systems.
Part of Heavy Motions’ 350 Series line, this pump features two 2" gear stages, a robust SAE 4-bolt “C” mount, and an outboard bearing for extra shaft support. Unlike the splined-shaft variant (423-9323-007), the 423-9323-008 uses a keyed shaft design, making it a perfect fit for applications requiring keyed shaft couplings.
Built with high-quality aftermarket components, this pump ensures reliable hydraulic performance, long service life, and direct compatibility with your existing Serco loader setup.
