Description
Bucher Wuxi Series Hydraulic Gear Pumps and Motors

Bucher Hydraulics’ Wuxi product portfolio includes a broad range of gear pumps and gear motors. The official Wuxi product index lists multiple frame and construction families, including compact CB-E, bidirectional CB-E variants, CBKA and CBKL units. This INTEREQ family page is an entry point for identification and quotation; it does not imply that all 40 listed catalogue entries share one specification.
This INTEREQ listing covers the Bucher Hydraulics Wuxi 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.

Applications
Compact mobile and industrial hydraulic systems where a Wuxi gear pump or gear motor is specified. Exact suitability depends on the unit’s displacement, mounting, port layout, rotational direction, pressure duty and the machine manufacturer’s requirements. 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 Wuxi listing includes small-displacement aluminium pump designs and bidirectional pump variants, alongside further gear-pump and gear-motor families. Construction details differ within the range. No family-wide displacement or pressure value is stated here because the official listing covers numerous separate products with different limits. Select by the complete nameplate code and the relevant Wuxi datasheet. 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.
