High pressure gear motors KM 5

Product catalog summary
Overview: The document provides detailed technical specifications and operational guidelines for the KM series high-pressure gear motors, primarily used in oil-hydraulic plants. These motors are compatible with hydraulic fluids, mineral oil bases, and engine oils, and are constructed with high-grade materials for durability and efficiency.
Specifications: The gear motors feature housing components made from high-grade cast iron, with shafts and gears crafted from hardened and ground case-hardening steel. They are supported by multi-layer bearings with excellent antifriction properties. The motors use NBR or FKM shaft seals, and an outboard bearing is included to manage radial and axial forces.
Technical Parameters: The document outlines various parameters such as volume flow, torque, and performance. Key formulas for calculating discharge flow, drive torque, and input power are provided. The motors can handle a working pressure of up to 40 bar at the outlet port, with specific temperature and viscosity ranges for optimal operation.
Performance Data: Performance data is provided for different nominal sizes (219, 250, 300) at various speeds (750, 1000, 1500 1/min). The data includes discharge flow, torque, and power output, highlighting the motor's efficiency under different operational conditions.
Construction and Design: The motors are designed with a robust construction to handle external radial forces. The direction of rotation can be clockwise or anticlockwise, affecting the oil flow direction. The document includes a type key for ordering, specifying options for seals, displacement, flange mounting, and shaft ends.
Connections and Dimensions: Detailed dimensions for flange types and shaft ends are provided, including specifications for SAE connections and spline profiles. The document also includes weight and mass inertia data for different motor sizes.
Product Portfolio: KRACHT GmbH offers a range of products including valves, hydraulics, flow measurement devices, and gear pumps, catering to various industrial applications.
