Axial Piston Pumps

Product catalog summary

Overview: This document outlines the technical specifications and operational guidelines for HPV Series Axial Piston Pumps, which are pressure-compensated and variable displacement pumps used in hydraulic systems.

Specifications:

Displacement Options: Five options available: 0.88, 1.26, 2.09, 2.62, and 3.78 cubic inches per revolution.
Pressure Ratings: Continuous pressure up to 3500 PSI, with intermittent capabilities up to 4000 PSI.
Mounting: Standard SAE flange for easy interchangeability.
Fluid Requirements: Use petroleum-based fluids with specific additives.
Operating Viscosities: Optimal at 140 sus (30 Cst), with a range from 60 sus (10 Cst) to 750 sus (160 Cst).
Temperature Limits: Fluid temperatures should not exceed 180°F (82°C) at the case drain.

Key Features:

Pressure Compensation: Adjusts displacement to match system flow, maintaining pressure and saving horsepower.
Remote Pressure Control: Allows remote pressure adjustments, suitable for variable flow systems.
Load Sensing Control: Provides constant flow with pressure adjustments based on load, enhancing efficiency.
Horsepower Limiting Control: Optimizes performance for varying pressure and flow scenarios.
Quiet Operation: Designed for reduced noise levels.
Rugged Construction: Cast iron body ensures durability.

Installation and Maintenance:

Mounting Position: Unrestricted, horizontal preferred.
Drive Shaft Alignment: Must be within 0.003 inches TIR for maximum bearing life.
Case Drain: Two ports available; only one needs connection to prevent drainage back into the reservoir.
Filtration: High-quality return line filter recommended to maintain fluid cleanliness to ISO 16/13 standards.
Relief Valves: Recommended to protect against overloads, set 200 psi above pump compensator setting.

Performance Data:

Efficiency: Varies with pressure, with detailed graphs provided for different models.
Noise Levels: Documented for zero and full flow conditions.

Ordering Information: Includes codes for shaft type, port configuration, compensator type, seal material, and rotation direction, with an example provided.
