POLARIS [PH 03 T A]

Product catalog summary

Introduction
The document introduces the "PH" series of hydraulic gear pumps and motors, an evolution of the "POLARIS" series, designed for high-performance applications such as forklifts and skid steer loaders. The series features a new cast iron body for enhanced operating parameters and reduced noise levels.

Features
The PH series offers high working pressure and volumetric efficiency, even at high temperatures, long service life, low noise levels, and high versatility with compatibility with Polaris 20 family components. Built-in valves simplify circuit design.

Specifications
Displacements range from 19.09 cm³/rev to 33.03 cm³/rev. The maximum continuous pressure is 3625 psi (250 bar), with a maximum speed of 3500 min^-1. The fluid temperature range is -13°F to 212°F (-25°C to 100°C), and the recommended viscosity range is 60 to 456 SSU.

Construction and Design
The pumps and motors feature heavy-duty external gear construction with 3-piece design. Mounting options include European, SAE, and German standard flanges, with direction of rotation options: anti-clockwise, clockwise, and reversible.

Performance and Efficiency
Volumetric efficiency is approximately 0.97 for pumps and 0.96 for motors. Hydro-mechanical efficiency is approximately 0.88 for pumps and 0.85 for motors, with overall efficiency at approximately 0.85 for pumps and 0.82 for motors.

Noise Reduction
The POLARIS PH series is designed to significantly reduce noise levels, with specific test conditions and performance curves provided for various pump models.

Multiple Pumps
The series allows for coupling multiple pumps, with the highest power requirement pump placed at the drive shaft end, featuring common inlet and separated stages for system efficiency.

Mounting and Installation
Detailed dimensions and mounting flange types are provided for various pump models, with rear cover materials available in cast iron and aluminum.

Conclusion

A CASAPPA FLUID POWER DESIGN FEATURES The new gear pumps and motors “PH” series is an evolution of the “POLARIS” series. “POLARIS PH” has a new body made of cast iron to have higher operating parameters and keep the full POLARIS versatility regarding shafts, flanges, ports and built-in valves. This project is targeted for forklifts, skid steer loaders and all those applications where traditional aluminum pumps are being pushed close to their limits. The possibility to mate the body with the cast iron covers further reduces noise levels, in addition to increasing strength. • High working pressure...

POLARIS series pumps can be coupled together in combination. Where the input power requirements of each section varies, that with the greater requirement must be at the drive shaft end, and progressively smaller to the rear. Features and performances are the same as the corresponding single pumps, but pressures must be limited by the transmissibletorque of the drive and connecting shafts. To have appropriate data, use the formula below. The maximum rotational speed is that of the lowest rated speed of the single units incorporated. Available with common inlet and separated stages.
