1-87310992-0 Isuzu 6UZ1 Engine Water Pump (China Stage III) for Sany / Sumitomo Excavator

Product Overview

1-87310992-0 is a genuine-quality water pump (coolant circulation pump) designed for Isuzu 6UZ1 series engines. Featuring an optimized high-flow impeller design, this water pump ensures continuous and efficient coolant circulation within the engine cooling system, maintaining optimal engine operating temperature. It is a core component of the engine cooling system.

This water pump is widely used in SANY, SUMITOMO and other excavator brands. In demanding mining, earthmoving, and other high-load continuous operation environments, engines run under long hours of load, heat, and vibration. This water pump is engineered specifically for such harsh conditions, effectively reducing the risk of overheating and supporting stable engine performance.
