Product Overview
Adopting an optimized closed-circuit bent-axis variable axial piston structure with spherical pistons, this motor is designed with a 32° maximum shaft angle and 0° zero-displacement function, delivering a 5:1 maximum-to-minimum displacement ratio. It operates stably under high working pressure, outputs high torque and wide speed range with extremely low flow pulsation and excellent volumetric efficiency.
Built with an integrated one-piece housing and easily maintainable external shaft seals, this motor is equipped with IP67/IP69K electrical protection and features strong resistance against 30G vibration and 50G mechanical shock. Multiple control modes including electric proportional control, hydraulic control and two-position control are optional, ensuring reliable performance in harsh working environments.
This motor is widely applicable to closed-circuit hydraulic drive systems for lifting machinery, mining equipment, concrete machinery, road machinery, marine & offshore facilities, construction machinery, agricultural machinery, forestry equipment and general industrial hydraulic systems.
Core Advantages
1. Integrated Structure Design - An Ideal Choice For Integrated Drive & Electrified Systems
Danfoss H1T Series Closed-Circuit Tandem Axial Piston Pump (H1T045 / H1T053 / H1T060 / H1T068) adopts optimized one-piece integrated tandem structure design, which is a dedicated configuration for integrated drive and electrified closed-circuit hydraulic systems:
Integrated connecting structure: It is equipped with standard spline shafts and reinforced shaft end structure. The robust shaft assembly bears external radial loads stably, and it is recommended to use flexible couplings to extend service life; Direct integration with multi-pump drive units: The tandem pump features through-drive design, which can be directly combined with other hydraulic pumps to form multi-pump groups without extra connecting parts, perfectly matching electrified hydraulic power modules; Compact axial dimension: As a compact tandem pump unit, the streamlined integrated housing greatly shortens the overall axial length, making it particularly suitable for equipment with extremely limited installation space; Easy installation: Standard SAE B/C mounting flanges, SAE O-ring boss and split flange port sizes as well as multi-bolt fixed layout enable seamless matching with user equipment and ensure excellent concentricity during operation. Besides, it supports reliable multi-pump tandem installation to optimize driving modes, further expanding system configuration flexibility for off-highway machinery.
2. H1T Series - High Performance Closed Circuit Tandem Axial Piston Pump
The Danfoss H1T Series stands for premium high-performance tandem axial piston pumps for closed circuits in Danfoss' product lineup:
High power density: Delivers stable large flow output within a compact housing. The whole series features 380–420 bar continuous differential working pressure, with a maximum peak pressure of 400–450 bar; Advanced cradle swash-plate & 9-piston assembly: Equipped with optimized cradle swash-plate variable mechanism and reinforced piston structure, it achieves higher mechanical efficiency and strong resistance to 30G vibration and 50G mechanical shock; High-stability flow distribution technology: The high-rigidity valve plate effectively prevents component tilting, features automatic wear compensation, maintains excellent volumetric efficiency in long-term operation and reduces pressure loss effectively. Benefiting from minimized dead volume and flow-optimized end caps, it also realizes extremely low flow pulsation; Harsh condition adaptability: This pump supports infinitely adjustable displacement for precise flow regulation. With IP67 and IP69K rated electrical connectors for control units, it can work stably with mineral oil, water-glycol fluid and synthetic hydraulic oil, and perform reliably on construction, mining, marine, road, agricultural and forestry machinery under severe working conditions. It provides multiple optional control modes including 12V/24V EDC electric proportional control, hydraulic control and forward-neutral-reverse control to meet diverse system demands.
