Product Overview
The Sauer Series 40 MPT044, MPT046, MPV044, MPV046 tandem hydraulic piston double pump with part number 84262356 is a high-performance variable axial piston pump. It adopts integrated dual pump structure to supply independent hydraulic power for travel and working circuits. Optimized swashplate control delivers stable variable flow output, and the compact housing fits well in limited installation space of compact construction equipment.
Features and Advantages
Precise control performance
Smooth variable adjustment: Swashplate control structure realizes continuous flow adjustment to match different working loads. Stable reversing performance: Bidirectional flow output supports forward and reverse movement of construction machines. Pressure overload protection: Built-in pressure limiting valve prevents system damage under sudden heavy load.
Efficient and reliable design
High efficiency design: High volumetric efficiency reduces energy consumption and improves fuel economy. Thermal balance optimization: Optimized internal flow channels to control oil temperature rise during long continuous operation. Impact resistance: Reinforced piston and valve plate components withstand vibration and shock on construction sites.
Application scenarios
This Sauer MPT / MPV series tandem double pump is the main hydraulic power source for compact track loaders. It is widely used in municipal engineering, landscaping and narrow-site construction works. It serves as OEM and replacement spare hydraulic part for compact construction machinery under continuous heavy-duty working conditions.
