H1 045 053 Single Axial Piston Pumps Datasheet

Product catalog summary

Introduction
Danfoss has been a leader in developing components and systems for mobile machinery used in off-highway operations for over 40 years. The company is recognized for providing high-quality hardware for vehicle applications.

H1 Range Overview
The H1 range is designed for quality, reliability, and ease of installation. It features advanced control systems and is available in various displacements. The range offers expanded functionality and greater total efficiency.

PLUS+1® Compliance
All H1 control and sensor options are PLUS+1® Compliant, allowing for rapid development and customization of electronic machine control. This system integrates machine controls and diagnostics into a cohesive operating network.

Key Features

Quality and Reliability: The H1 range is built on a single design concept with a single-piece swash plate.
Installation Benefits: The pump is length optimized with a minimum of one clean side, offering a higher corner HP/package size ratio and a standardized connector interface.
Wide Range of Controls: Includes electro-hydraulic controls such as Electrical Displacement Control (EDC), Forward-Neutral-Reverse (FNR), Non-Feedback Proportional Electric (NFPE), Automotive Control (AC), Fan Drive Control (FDC), and Manual Displacement Control (MDC).
Expanded Functionality: PLUS+1® Compliant control and sensor options, integral filtration with integrated filter bypass sensors and switch.
Efficiency: Minimized control losses, improved charge circuit, and lower control pressure for reduced power consumption.

Technical Specifications
The H1 Axial Piston Single Pump is available in sizes 045 and 053 cm³. Key parameters include:

Displacement: 45.0 cm³ [2.75 in³] for size 045 and 53.8 cm³ [3.28 in³] for size 053.
Input Speed: Minimum 500 rpm, rated 3400 rpm, maximum 3500 rpm.
System Pressure: Maximum working pressure is 420 bar [6090 psi] for size 045 and 380 bar [5510 psi] for size 053.
Case Pressure: Rated at 3.0 bar [40 psi], maximum 5.0 bar [75 psi].
Weight: 41.0 kg [90 lb] without PTO and filter.
