MPV046CBBHSAJBC4A Danfoss Series 40 Pump

Product Overview

The MPV046CBBHSAJBC4A, MPV046CBAJSBBAAAABJJABUEDANNN and related models (MPV035, MPV044, MPV046) belong to the Danfoss (formerly Sauer-Danfoss) Series 40 MPV series of high-pressure variable axial piston pumps (swashplate design). Designed for closed-circuit mobile hydraulic systems, displacement is continuously variable for high power density and reliable performance. Fully interchangeable with original Danfoss interfaces and performance (100% match), every unit undergoes 100% simulated operating condition testing. Ideal for mobile equipment, the series features precision swashplate technology, multiple control options, compact design and high efficiency.

5. Flexible configuration and system integration: Optional charge pump and auxiliary mounting pads for complex hydraulic systems.

Application Areas

Travel drives in construction machinery, agricultural equipment, material handling, rollers, industrial mobile equipment and closed-circuit hydrostatic systems requiring variable pumps.

Expert Maintenance Tips

Ensure the housing is correctly filled with oil and the case drain is connected before start-up to prevent dry-running damage. Use hydraulic fluid meeting recommended viscosity and cleanliness levels. Periodically inspect seals, controls and bearings; perform moderate-load break-in initially. Strictly observe maximum pressure and speed limits. When replacing, verify the complete model code (including control and shaft options) for full interchangeability. Refer to official Danfoss Series 40 technical manuals for precise flow-pressure curves.
