VARIABLE DISPLACEMENT AXIAL PISTON PUMPS

Product catalog summary

Overview: This document provides technical specifications and details for the TVP series of variable displacement axial piston pumps, designed specifically for truck applications. The pumps feature a swash plate design suitable for open circuit systems and are compact enough for direct mounting on PTOs (Power Take-Offs).

Specifications:

Displacement: Up to 84.7 cm³/rev (5.17 in³/rev).
Pressure: Maximum continuous pressure is 350 bar (5075 psi) and peak pressure is 400 bar (5800 psi).
Speed: Maximum speed is 2500 min^-1.
Direction of Rotation: Can be clockwise or anti-clockwise, as viewed from the drive shaft.
Hydraulic Fluid: Uses mineral oil-based hydraulic fluid conforming to DIN 51524.
Fluid Viscosity: Optimal range is between 15 and 35 cSt, with functional limits from 10 cSt to 1500 cSt.

Design Features:

Includes pump internal drain and compensators external drain line.
Equipped with flow and pressure compensator.
Compact design with low noise emission.
Body width is 124 mm (4.8819 in).

Filtration: To ensure optimal performance, the hydraulic fluid must maintain a contamination level within specified NAS 1638 and ISO 4406:1999 classes, achieved with a filter ßx(c) ≥75 according to ISO 16889.

Port Sizes and Configurations: The document details various port sizes and configurations, including SAE flanged ports and GAS straight thread ports, with specific tightening torques for low and high-pressure ports.

Displacement Settings: The maximum displacement setting range is from 55 to 84.7 cm³/rev, and the minimum is from 0 to 38.1 cm³/rev. Adjustments can be made via screw turns, affecting displacement by approximately 4.2 to 5.0 cm³/rev.

Additional Information: The document includes detailed dimensions and order examples for specific configurations, emphasizing the importance of filling the pump with oil before start-up to ensure proper operation.
