Eaton VSQ Vane Pumps

Product catalog summary

Introduction and Application
Eaton's VSQ Vane Pumps are designed for industrial applications, offering fixed displacement in single and double pump configurations. They comply with global SAE and ISO standards, with displacements ranging from 40 cm³/r to 90 cm³/r for single pumps and up to 180 cm³/r for double pumps. These pumps are ideal for high-speed and high-pressure operations, such as plastic injection molding and die-casting.

Features and Benefits
The pumps feature a hydraulically balanced design for extended shaft and bearing life, operating at speeds up to 3000 RPM with low noise levels. They are efficient under harsh conditions and offer easy maintenance with removable cartridges. The pumps are compatible with various fluids, including fire-resistant and biodegradable options.

Installation Notes
Proper installation is crucial for pump longevity. Avoid operating pumps at rated pressures at idle speeds for extended periods to prevent overheating. Ensure drive alignment and mounting dimensions adhere to specified tolerances to prevent premature failure.

Performance Data
The pumps provide continuous pressure ratings up to 280 bar, with peak pressures up to 310 bar. They offer high volumetric efficiencies, reducing energy and operating costs. Detailed specifications for different displacements and operating conditions are included.

Model Codes
Detailed model codes for single, thru-drive, and double pumps are provided, specifying series designation, frame size, displacement, mounting style, and other critical parameters.

Operational Recommendations

Introduction
This document provides technical specifications and guidelines for the operation and maintenance of Eaton VSQ Vane Pumps, including procedures for air removal, pressure requirements, fluid cleanliness, and hydraulic fluid recommendations.

Air Removal Procedures
To remove air from the system, loosen pump outlet fittings or use an air bleed valve before starting the pump. Ensure all inlet connections are tight to prevent air leaks. The system pressure at the pump inlet should not exceed 1.4 bar (20 psi), and the inlet hose should allow a fluid velocity of no more than 2.44 m/s (8 ft/sec).

Pressure Requirements
The minimum pressure differential between the outlet and inlet must be 3.5 bar (50 psig) to prevent premature pump failure. After priming, operate the pump unloaded for 5-10 minutes to remove trapped air. Ensure the fluid in the reservoir is clear.

Operating Temperature and Pressure
Minimum inlet pressure is 1.0 bar (14.5 PSI), with a recommended operating inlet pressure of 0 to 0.35 bar (0 to 5.0 PSI). Maximum positive inlet pressure is 1.4 bar (20 PSI). The maximum continuous operating temperature is 66°C (150°F), and the maximum intermittent temperature is 74°C (165°F).

Fluid Cleanliness Recommendations
Hydraulic fluid must be clean and contain the correct balance of materials and additives. Recommendations are based on ISO cleanliness levels at 2 µm, 5 µm, and 15 µm. Higher cleanliness codes can shorten the life of hydraulic components.

Hydraulic Fluid Recommendations
Fluid selection is crucial for the satisfactory operation of hydraulic systems. The fluid should have sufficient anti-wear additives, proper viscosity, and adequate rust and oxidation inhibitors. Recommended oils include anti-wear type hydraulic oils and automotive crankcase oils with specific SAE designations.

Conversion Factors and Additional Data
The document provides conversion factors for various units and practical hydraulic formulas for calculating flow rate, torque, power, and fluid velocity.

Conclusion
Proper adherence to the guidelines and specifications outlined in this document will ensure the efficient and long-lasting operation of Eaton VSQ Vane Pumps.

Pump characteristics. Rated pressure Pumps should not be operated at or near rated pressures at idle speeds for extended periods. Localized overheating and damage can result. Never assume pumps in a double, triple or thru-drive pump assembly can be simultaneously loaded to rated pressure. Shaft loading must be checked for excessive torque. Never load or unload a VSQ pump at rates greater than 10,342 bar/sec (150,000 psig/sec), because pump instability could occur. If unloading pump at rates over 5,171 bar/sec (75,000 psig/ sec), make sure inlet pressure does not fall below 0.83 bar (12 psi) absolute...
