KMER Series High-Torque Low-Speed Hydraulic Motor, 125–750 ml/r, Multiple Displacement Options

The KMER Series hydraulic motor is designed for hydraulic equipment requiring low-speed operation and high output torque. Its fixed rotor design combines low starting pressure with high working pressure and high torque output characteristics, making it suitable for industrial applications with defined drive and installation requirements.

With displacement options listed from 125 to 750 ml/r, the KMER Series gives equipment manufacturers flexibility when selecting a motor according to load requirements, target speed, hydraulic flow, and available mounting space

1.Design and Performance Features

Fixed Rotor Design: The advanced fixed rotor configuration supports hydraulic drive system design for specific operating conditions.

Low Starting Pressure: Helps address drive requirements during startup. Actual performance depends on system pressure, fluid condition, and external load.

Needle Roller Bearing Design: The catalogue states that this bearing arrangement can withstand higher axial and radial forces. Actual load limits should be verified for the selected model.

Low-Speed Operation: The high-speed distribution structure and automatic compensation design are described in the catalogue as supporting high volumetric efficiency and smooth low-speed movement.

2.Specification and Configuration Selection

When selecting a KMER Series hydraulic motor, evaluate four key factors:

1. Displacement: Match displacement to the target speed and available hydraulic flow. At the same flow rate, a larger displacement generally results in a lower theoretical speed, subject to operating conditions and efficiency.

2. Pressure and Torque: Check continuous and intermittent pressure ratings and torque data for the specific displacement. Do not select a model based only on the maximum value listed for the series.

3. Mounting Dimensions: Verify the mounting space, flange interface, and connection dimensions against the technical drawings.

4. Output Shaft Configuration: The PDF illustrates multiple output shaft options. Select the configuration that matches the machine's drive connection.

For replacement projects or new equipment development, provide the target speed, load torque, hydraulic flow, operating pressure, and mounting drawing to confirm the appropriate model.

3.Inquiry and Model Matching

Different machines have different load profiles, duty cycles, and mounting interfaces. Motor selection should consider displacement, operating pressure, output torque, target speed, and shaft connection together rather than comparing a single specification.

For an inquiry, please provide the required displacement or target speed, continuous operating pressure, load torque, mounting dimensions, and application details. For replacement projects, the existing motor model, nameplate photo, or interface drawing can help verify compatibility.
