Bucher APM External Gear Hydraulic Motor

Description

Bucher APM External Gear Hydraulic Motor

Bucher’s APM external gear motor family includes aluminium and cast-iron versions. The manufacturer lists unidirectional and reversible builds, several mounting patterns and options intended for auxiliary functions or external shaft loads. Shaft sealing and permitted back pressure depend on the selected configuration.

This INTEREQ listing covers the Bucher Hydraulics APM product family for identification, replacement enquiries and quotation support. Its product image is an original family illustration and does not depict a confirmed part number or selected configuration. Options and limits vary within a series; confirm the complete manufacturer code before ordering.

Technical specifications

Applications

Agricultural and construction machinery, winches, harvesting equipment and hydraulic tools, with model selection based on operating pressure, speed and load. Final suitability depends on the machine, hydraulic circuit, duty cycle and installed component configuration. Check the equipment documentation and the manufacturer’s current data before specifying a replacement.

Key features and compatibility

The family includes APM and reversible APMR designations, selected anti-cavitation valve options and outrigger bearing configurations for axial or radial loads. The listed displacement and pressure ranges vary by size. Confirm flange standard, shaft, rotation, port layout, case pressure and application duty against the full code. Interfaces are model-specific. Do not assume that units sharing a series name have matching shafts, flanges, ports, rotation, controls or seals. Published family ranges are identification guides and must not be treated as ratings for every size or combination.

Model identification and replacement selection

Do not select a replacement by brand and series alone. Compare the full nameplate code and confirm displacement, rotation, shaft, mounting flange, port arrangement, controls, case-drain requirements and hydraulic circuit against the installed unit and machine documentation. Send INTEREQ a clear nameplate photo and machine make/model for identification.

For a quotation, provide the full type code, machine model, operating conditions and any available drawing or nameplate image. Condition, availability and technical fit are confirmed for the specific unit offered.

System sizing and replacement check

For system sizing, compare pump displacement and shaft speed with the required flow, then check continuous and intermittent pressure against the machine duty cycle. Confirm inlet conditions, fluid viscosity and cleanliness, operating temperature, case pressure where applicable, drive power and external shaft loads. These conditions affect performance and service life; a series maximum is not an operating target for every unit.

When the installed type code is incomplete, include clear photos of the nameplate, mounting face, shaft and port layout. Provide the machine make/model, current circuit details and operating conditions so the replacement can be checked against the correct manufacturer data sheet.
