Product catalog summary

Features:
The Polaris series by Casappa S.p.A. includes hydraulic gear pumps and motors with displacements from 0.07 in³/rev to 5.56 in³/rev. They support a maximum continuous pressure of 3770 psi, intermittent pressure of 4060 psi, and peak pressure of 4350 psi, with a maximum speed of 4000 min-1. The design uses CAD 3D modeling, featuring aluminum alloy gear housing and sleeve bearings.

General Data:
Available in PLP and PLM series, these pumps and motors meet European, SAE, and German standards. They offer various mounting flanges and ports, with specified fluid temperature and viscosity requirements, recommending mineral oil-based hydraulic fluids.

Performance Curves:
Performance curves for Polaris 10, 20, and 30 series illustrate pressure and flow rate relationships at different displacements under specific conditions (122°F, oil viscosity of 168 SSU at 104°F).

Dimensions and Configurations:
Detailed dimensions for single and multiple pump units are provided, including drive shafts and mounting flanges configurations, built-in valves, and rotation change instructions.

Ordering Information:
