When maintaining concrete pump trucks, the hydraulic pump is a critical component—and selecting the right replacement parts is essential for stable performance and effective repairs. Especially for widely used KAWASAKI models like K5V200, K3V112, and K3VL80, part compatibility and quality are crucial.

Here are key tips to help you make the right selection:

✅ 1. Confirm the Truck and Pump Model

Typical match examples include:

• Putzmeister/SANY → often use K5V200

• Schwing/XCMG → usually paired with K3V112 or K3V140

• Liebherr → commonly uses K3VL series

Use the pump nameplate, old pump housing number, or service manual to confirm your model.

✅ 2. Prioritize High-Precision Aftermarket Parts

Choose parts made from alloy steel, CNC-machined, and heat-treated for excellent wear resistance and sealing. These features are vital for handling high pressure and heavy-duty pumping operations.

✅ 3. Replace Key Components as a Complete Set

Focus on replacing the following:

• Piston & Shoe Assemblies

• Cylinder Block & Valve Plates (LH/RH)

• Drive Shaft (Left/Right)

• Swash Plate, Ball Guide, Spring, Support

Replacing the full set avoids imbalance and ensures smooth operation.

✅ 4. Ensure OEM Number Matching and Technical Support

A reliable supplier will provide part numbers that correspond to OEM specs and offer installation guides, technical assistance, global shipping, and warranty coverage.

✅ Summary

Choosing the correct hydraulic pump parts is fundamental to ensuring your concrete pump truck operates efficiently and stays reliable. With KAWASAKI pumps widely used, attention to quality and fit is non-negotiable. Work with experienced, fast-responding, and full-range suppliers to ensure repair success.
