NSH10-10-4 Compact Tandem Hydraulic Gear Pump

NSH10-10-4 Tandem Gear Pump

Olive Branch Hydraulics supports China-manufactured NSH10-10-4 tandem gear-pump enquiries for Russian and CIS mobile-equipment markets. The nominal displacement reference is 10 + 10 cm³/rev. Send the full old-pump marking and installation details to confirm both sections, the drive connection and rotation before quotation.

Two Small Pump Sections

The reference assembly has two similar-size pump sections connected in line, a four-hole front mounting flange and separate oil-port connections visible on each section. It differs from the larger-front-section NSH32-10 and NSH100/50A-3 assemblies. A common drive does not make the sections interchangeable with two unrelated single pumps. Check available mounting space, coupling, section order and the actual inlet and outlet arrangement for the complete assembly.

NSH10-10 Model Markings

Search references include NSH10-10, NSh10/10, NSH10-10-4, НШ10-10-4 and НШ-10-10-4R. The supplier reference sample is identified as the right-rotation -4 version. A shortened NSH10/10 enquiry does not establish the pressure execution, shaft, oil-port arrangement or mounting interface. Keep all suffixes on the old marking when requesting a quotation. Do not treat -3 and -4 executions as the same configuration or assume an assembled pump can be reversed in service.

Photographs and Supply Confirmation

The three views are supplier reference photographs for the NSH10-10-4 family, not photographs of an Olive Branch manufacturing batch. Other-brand graphics have been removed from the edited reference views; the photographs are not evidence of an Olive Branch nameplate. The shaft-end view retains the protective shaft cover, so spline count and shaft dimensions cannot be verified from that picture. Request the approved installation drawing and confirmation photographs for the quoted configuration.

Information Required for Selection

Provide the complete model marking, requested rotation viewed from the shaft end, mounting-bolt spacing, locating diameter, shaft diameter and spline profile. Include oil-port dimensions for both sections, overall installed length and the required pressure and speed for each circuit. Add machine model, parts-book reference and order quantity when available. A tractor name alone does not prove that this configuration will fit.

Nominal displacement is an enquiry reference rather than a measured production result. Rated pressure, peak pressure, permissible speed, efficiency, oil specification and temperature limits must follow the supplied assembly's approved data sheet. Catalogue ratings from another manufacturer are not transferred into an Olive Branch performance guarantee. OEM/ODM supply and sample review can be discussed using the installation requirements.

Frequently Asked Questions

What does 10-10 indicate?

It is the nominal 10 + 10 cm³/rev displacement combination. Confirm both sections and their order on the final specification.

Is this the same assembly as NSH32-10?

No. The reference assembly uses two small sections; the NSH32-10 uses a different displacement combination. Compare the full mounting and drive details.

Can I order using only NSH10/10?

Include the full marking, photographs and installation dimensions. The short name does not specify every configuration detail.

Does the reference show the shaft splines?

No. A protective cover is fitted in the shaft-end photograph. Request an uncovered shaft photograph and dimensioned drawing before approving the drive connection.

Are both rotations available?

The reference listing identifies right rotation. Confirm availability of the requested direction for the exact quoted assembly.

What pressure and speed can it run at?

Use the approved data sheet for the supplied configuration, with limits for both sections and the complete assembly. Do not select operating limits from the short model name alone.
