KAPPA 30 CHS

Product catalog summary

Overview: The document provides comprehensive technical specifications and ordering information for the Kappa 30 series hydraulic pumps and motors, including both single and double units. It covers various configurations, port types, drive shaft options, and ordering codes, ensuring users can select the appropriate model for their needs.

Features: The Kappa "Compact" line is noted for its solid 2-piece construction, high operating pressures, low noise emission, and built-in valves. It offers flexibility with multiple drive shafts, mounting flanges, and ports.

General Data: Displacements range from 19.63 cm³/rev to 81.68 cm³/rev, with a maximum pressure of 320 bar and a speed of 3000 min^-1. The document specifies the use of mineral oil-based hydraulic fluids and guidelines for fire-resistant fluids, along with contamination class requirements and filtering needs.

Specifications: The document details specifications for different pump and motor types, including displacement, body design, performance, maximum pressure, and speed. It includes tables for selecting the appropriate pump or motor type based on these parameters.

Ordering Information: Instructions for ordering pumps and motors include type codes, rotation codes, drive shaft codes, port codes, seal codes, and drain port codes. Examples are provided to illustrate the ordering process.

Mounting and Ports: Descriptions of mounting flange options and port types are provided, including SAE flanged ports, SAE straight thread ports, and GAS straight thread ports, with dimensions and tightening torque specifications.

Double Pumps: The KAPPA series allows for coupling pumps in combination, with guidelines for input power requirements and torque limits, emphasizing that the section with the greater requirement should be at the drive shaft end.

Materials and Torque Specifications: Information on rear cover materials (aluminum or cast iron) and corresponding screw tightening torques is included, with specific values for low and high-pressure side ports.

Reversible Rotation: Special instructions are provided for pumps with reversible rotation, including specific torque values for high-pressure side ports.

Norms and Standards: The pumps conform to SAE J744 and ANSI B 1.1 for thread specifications, with British standard pipe parallel (55°) conforming to UNI - ISO 228.

Recommendations: Users are advised to choose seals according to temperature requirements and ensure the torque absorbed by the shaft does not exceed the maximum limit. Additional features of the Polaris 20 model are available in the technical catalog.

Key Data from Tables: The document provides detailed tables listing various pump types with their respective displacements, dimensions, and port codes, ensuring users can select the appropriate model for their needs.

3 CASAPPA FLUID POWER DESIGN FEATURES From the KAPPA series, we now introduce the KAPPA “Compact” line. The main feature of this new line is a solid compact 2-piece construction. The new Kappa “Compact” line allows you to include many functions in a reduced space. The new KAPPA “Compact” line is a direct result of feedback received from Casappa customers. This feedback has given Casappa the opportunity to understand the needs of our customers and implement the hydraulic knowledge gained into new and improved products. The “Compact” line provides exceptional quality and reliability thanks to tri-dimensional...
