Weichai WP10.270 Water Pump – OEM Engine Cooling Pump

 Weichai Engine WP10.270 Water Pump – Complete Specification & Overview

Product Introduction

The Weichai WP10.270 water pump is a genuine engine cooling component designed specifically for the WP10 series diesel engines. It ensures consistent coolant circulation, maintains optimal operating temperatures, and prevents overheating in heavy‑duty applications including commercial trucks, construction equipment, and marine vessels.

This pump is manufactured to original equipment specifications, using high‑grade cast iron housing and a precision‑balanced impeller for long service life under extreme loads.

Key Technical Specifications

Detailed Feature Breakdown

1. Durable Cast‑Iron Housing
The pump body is precision‑machined from corrosion‑resistant cast iron, providing excellent resistance to thermal stress and cavitation. This extends the pump’s lifespan even in dusty or high‑humidity environments.

2. High‑Efficiency Closed Impeller
The six‑vane closed impeller delivers stable coolant pressure across all RPM ranges, reducing air pockets and ensuring even cooling for all engine cylinders.

3. Advanced Mechanical Seal
The integrated ceramic‑to‑carbon mechanical seal eliminates coolant weepage, protects the bearing assembly, and reduces maintenance frequency compared to conventional packing seals.

4. Maintenance‑Free Bearing System
Pre‑lubricated, double‑row sealed bearings require no periodic greasing, lowering your total cost of ownership and minimizing downtime.

5. Direct Bolt‑On Replacement
The pump uses standard 4‑bolt flange mounting with M10 studs, matching the original Weichai engine layout. No adapter plates or modifications are needed.

Compatible Applications

This water pump is suitable for vehicles and equipment powered by the Weichai WP10.270 engine, including:

• Heavy‑duty trucks (e.g., Howo, Shacman, Dongfeng)

• Urban and intercity buses

• Construction machinery (loaders, excavators, rollers)

• Agricultural tractors and harvesters

• Marine auxiliary engines

Always verify your engine serial number and original pump part number before ordering.

Installation & Maintenance Tips

• Before installation, flush the cooling system to remove old debris or scale.

• Replace the thermostat and coolant at the same time for optimal performance.

• Torque the mounting bolts to 45–50 Nm in a cross pattern.

• After installation, run the engine at idle for 5 minutes and check for leaks around the seal and gasket surface.

• Inspect the drive belt tension – excessive slack can reduce pump efficiency.
