PowrFlow™ PVR Series Vane Pumps

Product catalog summary

Introduction
Continental Hydraulics' PowrFlow™ PVR Series Vane Pumps are engineered for demanding applications, offering robust and reliable performance. These pumps are pressure compensated, providing faster response and requiring less external compensation compared to piston pumps in harsh environments.

Features and Benefits

Rated at 1500 PSI at full flow.
Available in sizes from 4 to 70 gallons.
100% tested with a three-year warranty.
Quiet operation with noise levels as low as 68 dBa.
Balanced vane tip loading for extended life.
Patented pressure balanced thrust plates for up to 90% efficiency.
Direct spring-operated compensator for fast pressure compensation.
Patented walking ring for even wear distribution and longer pump life.
Heavy forged one-piece rotor shaft for increased pump life.
Hydrodynamic journal bearings for virtually unlimited pump life.

How a Vane Pump Works
The vane pump operates with a variable volume and constant pressure mechanism. As the rotor turns, the volume between vanes increases at the suction port and decreases at the pressure port, forcing fluid out. The system maintains constant pressure from zero to full displacement.

General Specifications

Recommended fluids include petroleum base and most phosphate ester fluids.
Viscosity limits are specified, with start-up at 1000 SUS intended for warm-up only.
Operating temperature should not exceed 160°F for optimal performance.
Filtration recommendations vary based on fluid type.
Drive coupling and shaft alignment specifications are provided for maximum bearing life.
Relief valves are recommended for pressures above 1500 psi.

Performance and Options
The PVR Series offers variable displacement and pressure compensation, with options for tandem mounting and various control configurations. Performance curves and specifications are provided for different pump sizes, detailing efficiency, sound levels, and pressure/volume adjustments.

Ordering Information
Ordering codes are provided for selecting pump size, compensating pressure range, seal type, and mechanical options, allowing customization based on specific application needs.

Specifications

PVR-6 Series: Available in sizes 4B, 6B, 8B, and 10B with volumetric displacement ranging from 0.7 to 1.4 cu. in./rev. Maximum compensated pressure is 2000 psi for most models, except 10B which is 1000 psi.
PVR-15 Series: Available in sizes 15B, 20B, and 30B with volumetric displacement ranging from 2.4 to 4.3 cu. in./rev. Maximum compensated pressure is 2000 psi for 15B, 1500 psi for 20B, and 1000 psi for 30B.

Performance

Overall efficiency is measured at 1750 rpm at full displacement.
Typical sound levels and pressure-volume adjustment sensitivity are provided for different pump sizes.

Operating Conditions

Minimum and maximum operating speeds are specified, with recommendations for using relief valves at pressures above 1500 psi.
Fluid velocity and specific gravity considerations are outlined for optimal performance.

Mechanical Options

Various mechanical options are available, including maximum volume control, handwheel pressure control, and tandem pump configurations.

Ordering Information

Details on selecting pump size, compensating pressure range, and mechanical options are provided.
Specific codes for seals and mechanical options are included for accurate ordering.

Notes

Performance curves are based on ISO VG46 oil at 120°F. Adjustments are recommended for different oil viscosities.
Deadhead horsepower is noted for zero flow conditions.

Specifications The PVR-15 series includes models such as 15B15, 15B20, 15B3L, and 15B5L, all operating at 1750 rpm. The PVR-50 series includes models like 32A15, 42A15, 50B15, and 70B15, with varying volumetric displacements and pressure ranges. The pumps are designed to handle pressures up to 2000 psi and flow rates up to 70 gpm.

Performance Curves Performance curves are provided for different models, showing the relationship between pressure, flow rate, and horsepower. These curves are based on ISO VG46 oil at 120°F (49°C). Adjustments for oil viscosity above 400 SUS are noted.

Dimensions Detailed dimensions are provided for both flange-mounted and manifold-mounted configurations, including specifications for right-hand and left-hand rotations. Key dimensions include pressure and suction port sizes, as well as mounting details.

Mechanical Options Various mechanical options are available, including handwheel pressure and volume controls, external spline shafts, and tandem pump mounting configurations. Specific codes are provided for ordering these options.

Ordering Information The document outlines the typical ordering codes for both flange-mounted and manifold-mounted pumps, detailing the selection of flow rates, pressure ranges, seal types, and control options.

Notes The document includes important notes on operating conditions, such as the recommendation for a direct-acting differential relief valve when operating above 1500 psi to manage pressure spikes.

Specifications The document outlines the dimensions for various components such as foot mounting brackets, manifold dimensions, and straight flanges. It provides measurements in both inches and millimeters, ensuring compatibility with different systems.

Ordering Information Detailed ordering codes are provided for foot mounting brackets, bolt kits, and manifold kits. The document specifies the compatible pump models and sizes, along with the weight of each kit in pounds and kilograms.

Mounting Accessories The document includes information on transition plates for mounting different pump models, specifying the necessary bolts and washers. It also details the dimensions and components included in each kit.

Performance Specifications The document describes the typical performance of the air bleed valve, including minimum flow rates, operating pressures, and closing times. It highlights the benefits of using pressure-compensated vane pumps, such as reduced heat build-up and smaller motor requirements.

Warranty and Support Continental Hydraulics offers a three-year warranty on their vane pumps, covering defects in material and workmanship. The document emphasizes the company's strong distribution network and commitment to customer service.
