Danfoss MPT044 Tandem Pump | MPT044DAWS, MPT044DAWSJB | Axial Piston Pump | Dual Circuit

Danfoss MPT044 Series Axial Piston Tandem Variable Pumps

Product Overview: The Danfoss MPT044 series is a high-efficiency tandem axial piston pump specifically designed for compact mobile machinery requiring closed-circuit hydrostatic drives. This integrated dual-pump solution houses two independently controlled variable displacement pumps on a single drive shaft, making it ideal for dual-path drive systems. Featured models like the MPT044DAWSJB deliver unparalleled performance. With its compact frame and precise DA (Speed Related) control logic, the MPT044 provides smooth, coordinated power at a rated pressure of 210 Bar, specifically optimized for tandem rollers, skid steer loaders, and professional mowers.

Key Technical Advantages:

• Efficient Tandem Integration: Single-shaft drive for two independent pumps significantly saves installation space at the engine end and simplifies transfer case requirements.

• Precise DA Control Logic: The DA (Direct Acting) speed-sensing feature automatically modulates displacement based on engine RPM, providing superior drive feel and anti-stall protection.

• Closed-Loop Optimization: Designed for frequent reversals and bi-directional driving, featuring an integrated charge system to ensure stable operation of both circuits under fluctuating loads.

• Industrial-Grade Durability: Constructed with high-strength materials and reinforced bearing groups, engineered for a long service life in harsh, vibrating, and dusty construction environments.

• Modular Configuration: Models like the MPT044DAWSJBABAAAB support various control positions and shaft specifications, allowing flexible matching with various compact hydraulic chassis.
