PowrFlow™ PVX Vane Pumps

Product catalog summary

Introduction and Benefits
Continental Hydraulics introduces the PowrFlow™ PVX Vane Pumps, engineered for demanding applications requiring reliable and efficient hydraulic power. These pumps feature variable displacement and pressure compensation, ideal for environments prioritizing low noise and high performance. Key features include continuous duty ratings, a speed range of 1150 to 1750 rpm, and compliance with SAE, ISO, NFPA, and ANSI standards. They are competitively priced and come with a three-year warranty.

Features and Benefits

Rated at 3000 PSI for most models with flow sizes from 8 to 75 GPM.
Compact design saves space.
Pressure compensation adjusts delivery to demand, conserving energy.
Fast response and recovery times.
Quiet operation and 100% tested.
Available compensator options include single stage, two stage, load sensing, and torque limiting.
Tandem pump capability with splined shaft and tandem mount cover.

Specifications
PVX pumps are available in various models with specific performance specifications. For example, the PVX-8 model has a nominal displacement of 1 in³/rev, a maximum continuous pressure of 3000 psi, and a speed range of 1150 to 1800 rpm. The pumps are designed for right-hand (clockwise) rotation and have unrestricted mounting positions.

Performance Graphs and Dimension Drawings
The document includes performance graphs showing sound pressure levels, output flow, input horsepower, and efficiency at different pressures. Dimension drawings provide detailed measurements for installation and configuration.

Control Options and Repair Parts
Control options include single stage, two stage, load sensing, and solenoid-operated two pressure controls. Repair kits and parts are available for maintenance and servicing.

Applications
PVX Vane Pumps are suitable for use in machine tools, steel mills, mines, shipyards, foundries, automobile plants, textile mills, pulp and paper mills, and other industries requiring reliable hydraulic power.

Operational Guidelines

Drive Connection: Pumps should be connected to the prime mover using a flexible coupling, aligned to a maximum of 0.006” (.152 mm) to prevent noise, vibration, and seal wear.
Fluid Recommendations: Use premium quality hydraulic oil with anti-wear additives. Consult the factory for compatibility with water-based fire-resistant fluids.
Temperature: Inlet fluid temperature should not exceed 140°F (60°C). Select fluids for optimal viscosity at operating temperatures.
Filtration: Fluid cleanliness should meet ISO/DIS 4406 standards, with cleanliness levels of 18/15 or better for pressures up to 2000 psi, and 17/13 for pressures between 2000 to 3000 psi.

Performance Data

Response Time: Full flow to minimum flow response time is 20-40 ms, depending on the circuit.
Weight: Single-stage pumps weigh between 61 lbs (27.7 kg) and 120 lbs (55 kg), while two-stage pumps weigh between 65 lbs (29.4 kg) and 128 lbs (58 kg).
Sound Pressure Levels: Measured in a hemi-anechoic chamber, sound levels vary with pressure and rpm.

Diagrams and Tables
The document includes detailed diagrams and tables illustrating dimensions, flow rates, efficiency, and sound pressure levels for each pump model.

Control Systems
The document outlines various compensator codes for pressure control, including two-stage, load sense, single-stage, torque limiting, and solenoid vent compensators. Each type has specific applications and benefits, such as maintaining constant flow or reducing horsepower demand during idle cycles.

Installation and Maintenance
Detailed instructions are provided for the installation of bearings, torque ratings, and the use of repair kits. The document emphasizes the importance of proper alignment, pressure settings, and the use of recommended lubricants and sealants.

Troubleshooting
Common issues such as excessive noise, failure to prime, instability, and overheating are addressed with potential causes and remedies. Proper alignment, pressure adjustments, and ensuring adequate fluid levels are highlighted as critical factors for optimal pump performance.

Warranty and Support
Continental Hydraulics offers a three-year warranty on PVX Vane Pumps against defects in material and workmanship. The company provides extensive support through a network of experienced distributors and engineers to assist with product selection and problem-solving.

Applications
PVX Vane Pumps are suitable for demanding applications, including plastic molding machinery, machine tools, marine auxiliary power controls, and more. The pumps are designed to meet stringent sound level requirements and provide smooth, pulsation-free operation.
