NSH32-32D-4 Tandem Hydraulic Gear Pump With 32+32 Cc Sections

NSH32-32D-4 Tandem Gear Pump

Olive Branch Hydraulics supports China-manufactured NSH32-32D-4 tandem gear-pump enquiries for Russian and CIS hydraulic equipment. The nominal combination is 32 + 32 cm³/rev: two pump sections driven by one shaft. Send the complete old-pump marking and installation details to confirm the required execution and rotation before quotation.

Two Sections in a Compact Assembly

The supplier reference sample has two similar-size aluminium housing sections, a central connecting area and a four-hole front mounting flange. Separate machined oil-port faces are visible on both sections. The rear-cover photograph shows the back of the complete assembly, while the side and angled views show its length and section arrangement.

This is the 32+32 D-4 enquiry family. It differs from the 16+10, 32+10 and 50+50 combinations. A similar appearance or shared flange style does not establish identical displacement, installed length, shaft capacity or pressure execution. Use the exact installation drawing for the assembly being offered.

Model Markings and Russian Search Forms

Relevant names include NSH32-32D-4, NSh32-32D4, NSH32/32, НШ32-32Д-4 and НШ-32-32Д-4. Shortened NSH32-32 and НШ32-32 descriptions help identify an enquiry but leave the complete execution undefined. Keep all letters and suffixes from the original marking. The Cyrillic Д is normally written D in Latin enquiries.

Do not assume NSH32-32M-4, NSH32-32D-3 or an unsuffixed 32/32 assembly is interchangeable with this D-4 reference. Differences in the shaft, mounting, ports and operating limits must be reviewed. Provide the machine parts-book number when available rather than relying on a general tractor model.

Rotation, Ports and Drive Matching

The photographed supplier reference is listed as right rotation. Confirm the required direction viewed from the drive-shaft end in writing; a catalogue photo does not determine the order configuration. The assembled unit must not be assumed reversible. The supplied coupling, shaft profile, spline engagement and combined drive torque must suit both sections.

Measure the locating diameter, mounting-bolt spacing, flange thickness, shaft dimensions, every oil-port connection and available installation space. Confirm the section order and actual inlet/outlet routing. Equal displacement does not mean that both circuits have the same pressure requirement or that their outlets can be connected together without reviewing the hydraulic circuit.

Operating Specification and Reference Photos

State the working and peak pressure, speed range, oil viscosity and temperature conditions for each circuit. Permissible pressure, shaft loads, support requirements and operating limits follow the approved data sheet for the exact supplied assembly. Values shown by another supplier are not an Olive Branch production test result.

The three photographs are supplier reference views, not photographs of an Olive Branch production batch. They show the oil-port side, front angled view and rear assembly. Request confirmation photographs and the installation drawing for the quoted configuration. OEM/ODM supply and sample review can be discussed using the installation information, order quantity and destination.

Frequently Asked Questions

What does 32-32 mean?

It identifies a nominal 32+32 cm³/rev two-section combination. Confirm each section's precise specification before ordering.

Is it the same as NSH32-10?

No. The second section has a different nominal displacement, and the complete assembly must be matched separately.

Are M and D executions interchangeable?

Do not assume so. Compare the complete model, installation drawing and operating specification.

How is rotation specified?

State clockwise or counterclockwise viewed from the drive-shaft end, and keep any rotation suffix on the old pump marking.

Can I use it on any tractor?

Compatibility requires the machine reference, measured interfaces and circuit requirements. A general tractor description is insufficient.

What should I send for a quotation?

Send the complete marking, old-pump photos, shaft and mounting measurements, oil-port dimensions, operating conditions and quantity.
