NSH16-10 Tandem Hydraulic Gear Pump With 16+10 Cc Sections

NSH16-10 Tandem Hydraulic Gear Pump

Olive Branch Hydraulics supports China-manufactured NSH16-10 tandem gear-pump enquiries for Russian and CIS equipment. The nominal displacement combination is 16 + 10 cm³/rev. Two pump sections share a mechanical drive while serving separate hydraulic circuits. Send the complete old-pump marking and installation measurements to confirm the quoted configuration.

A Compact Unequal-Section Assembly

The reference photographs show a larger front section with a smooth aluminium housing and a smaller rear section with external ribs. The front has a four-hole mounting flange, and the drive shaft is covered by a protective cap. Oil-port faces are visible on both sections. This configuration belongs to the 16+10 enquiry family; it must not be selected using the dimensions or photographs of the NSH32-10, NSH10-10 or NSH50-50 assemblies.

The displacement combination determines the nominal flow relationship between the circuits at a common shaft speed. Actual delivered flow also depends on speed, pressure, oil condition and volumetric efficiency. Confirm the section order and inlet/outlet routing on the supplied drawing rather than assuming that every tandem uses the same connections.

Model Names and Complete Identification

Search forms include NSH16-10, NSh16/10, NSH16-10M-3, NSH16-10M-3L, НШ16-10М-3 and НШ16-10М-3Л. Supplier listings also use НШ16-10Д-3 and НШ16-10Д-3Л. These are enquiry references, not a declaration that different M, D or pressure executions are interchangeable. Keep the complete marking, including rotation and execution suffix, when requesting a quotation.

Some supplier page titles and detailed model fields use different rotation suffixes. Therefore, specify clockwise or counterclockwise rotation viewed from the drive-shaft end and obtain written configuration confirmation. The assembled pump must not be assumed reversible. The protective cap in these photographs prevents a reliable count or measurement of the drive splines.

Measurements Required Before Ordering

Provide the mounting-bolt spacing, locating diameter, flange thickness, shaft profile and usable shaft length. Include the dimensions and connection type of every oil port, the required orientation, available installation space and total length of the old pump. Add the machine model and parts-book reference where available. A general MTZ or tractor description does not establish compatibility.

For each circuit, state the required working pressure, peak pressure and speed range. The combined drive torque and the limits of each section need review. Pressure ratings, permissible shaft loads, oil viscosity, temperature and support requirements follow the approved specification of the quoted assembly. Another manufacturer's catalogue values are not an Olive Branch test result.

Reference Photos and Supply Enquiry

The images are edited supplier reference views with other-brand logos removed. They are not photographs of an Olive Branch production batch and do not establish an Olive Branch nameplate or an exact shaft specification. Request confirmation photographs and the installation drawing for the configuration offered. OEM/ODM and sample review can be discussed with the required quantity and installation information.

Frequently Asked Questions

What does 16-10 identify?

It is a nominal 16+10 cm³/rev tandem combination. Confirm the actual specification of both sections before ordering.

Is this the same as NSH32-10?

No. The front section has a different nominal displacement, and installation dimensions must be checked independently.

Are M and D suffixes interchangeable?

Do not assume so. Use the full old-pump code and compare the approved drawings and operating specifications.

Can the shaft splines be confirmed from these pictures?

No. The reference shaft is capped. Send a clear uncovered shaft photograph and measurements.

Can I choose left rotation?

State the required shaft-end rotation in the enquiry. Availability and the exact execution are confirmed in the quotation.

What information helps obtain an accurate quotation?

Provide the complete marking, all-side photos, installation measurements, circuit requirements, quantity and destination.
