Product catalog summary

Features
KAPPA hydraulic gear pumps and motors are designed with robust cast iron housing and mounting flange, adhering to SAE and European standards. They offer high volumetric efficiency and reliability under high operating pressures, suitable for applications where noise, contamination, non-flammable fluids, and compact size are critical. Key features include high operating pressures, efficiency at high temperatures, and long working life expectancy.

Specifications
Displacements range from 0.30 in³/rev (4.95 cm³/rev) to 4.50 in³/rev (73.82 cm³/rev). Maximum continuous pressure is 4133 psi (285 bar), with intermittent and peak pressures reaching 4350 psi (300 bar) and 4785 psi (330 bar) respectively. Maximum speed is 4000 min⁻¹.

Construction and Standards
The pumps and motors are of the external gear type, with mounting options conforming to European, SAE, and ISO standards. They support various line connections and rotation directions, including anti-clockwise, clockwise, and reversible.

Fluid and Temperature Specifications
Compatible with mineral oil-based hydraulic fluids and fire-resistant fluids, with a viscosity range from 60 to 456 SSU. The fluid temperature range is specified in a table, with different seal options available based on fluid type.

Performance Curves
Performance curves for KP 20 and KP 30 models show efficiency and pressure capabilities at specified temperatures and viscosities.

Design Calculations
Formulas for calculating delivery, torque, power, and efficiency are provided, with diagrams for selection data.

Standards and Ports
Details on European and SAE standard ports, including dimensions and tightening torques, are included for various pump types.

General Notes
Different inlet and outlet ports are available, and specific fluid types should be specified when ordering. Casappa recommends using its own production filters for optimal performance.

Overview
The document provides detailed specifications and ordering information for KAPPA series hydraulic gear pumps, specifically the KP 20 and KP 30 models. It includes technical data, ordering codes, and torque specifications.

Torque and Pressure
The tightening torque for screws is specified as 70 ±7 Nm (558 ÷ 682 lbf in). The document outlines the maximum torque limits for different drive shaft configurations, with values ranging from 620 lbf in (70 Nm) to 4426 lbf in (500 Nm) depending on the version and application.

Ordering Information
The document provides a detailed guide on how to order single and multiple pumps, including codes for pump type, rotation, version, drive shaft, mounting flange, ports position, ports IN/OUT, and seals. Examples of standard and special version orders are provided.

Multiple Pumps
KAPPA series pumps can be combined in multiple configurations, with specific guidelines on power requirements and torque limitations. The document includes a formula for calculating the torque absorbed by the drive shaft and notes on the maximum rotational speed.

Key Data from Tables
The tables provide dimensions and port codes for various pump types, with measurements in both metric and imperial units. The tables also specify the type of threads and ports for each pump model.

Recommendations
The document advises selecting seals based on temperature conditions and provides guidance on the appropriate use of multiple pump configurations to ensure optimal performance and avoid exceeding torque limits.

Specifications
The document provides detailed specifications for the Kappa 30 hydraulic gear motors, including various motor types, rotation options, versions, drive shafts, mounting flanges, ports, and seals. It specifies torque limits for different versions and applications, highlighting the maximum permissible torque for each configuration.

Ordering Information
Instructions on how to order single motors are provided, detailing the coding system for motor type, rotation, version, drive shaft, mounting flange, ports position, ports IN/OUT, and seals. Examples of standard and special version motor orders are included.

Installation Instructions
The document outlines installation procedures for pumps and motors, emphasizing the importance of matching the direction of rotation with circuit connections and using flexible couplings to avoid axial or radial loads. It also provides guidelines for tank capacity, line diameters, and the use of filters to maintain system cleanliness.

Hydraulic Fluid and Starting Up
Recommendations for hydraulic fluid conforming to ISO/DIN standards are given, along with starting up procedures to ensure system cleanliness and proper operation. The document advises on gradually increasing pressure and speed to reach pre-set operating levels.

Maintenance
Regular maintenance checks are advised, including keeping the drive shaft seal area clean, replacing filters, and checking oil levels periodically to ensure optimal system performance.

Additional Information
The document includes technical drawings and dimensions for various motor types, permissible radial loading details, and contact information for CASAPPA S.p.A., the manufacturer.
