Bucher QXEH High-Dynamic Internal Gear Pump

Description

Bucher QXEH High-Dynamic Internal Gear Pump

Bucher developed the QXEH family for highly dynamic variable-speed pump duties, including servo drives with reversing function. The internal gear design is intended for applications with changing load cycles and demands on power density and energy use. Each frame has its own displacement, pressure and speed limits.

This INTEREQ listing covers the Bucher Hydraulics QXEH 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

Hydraulic presses, injection-moulding machines, machine tools, waste compactors, lift drives, pressure die-casting equipment and hydraulic power units, subject to model configuration. 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

Manufacturer specifications describe low flow and pressure pulsations during dynamic cycles and allow selected double-pump arrangements, bolt-on valves and pipe flanges. The series maximums do not apply to every size or operating point. Confirm oil, shaft, rotation, flange, ports and the complete code before ordering or replacing a unit. 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.
