NSH100M-3 Hydraulic Gear Pump For Mobile Equipment

NSH100M-3 hydraulic gear pump

NSH100M-3 has a nominal displacement of 100 cm³/rev and belongs to the large-displacement M-series external gear pump family. Olive Branch Hydraulics is a Chinese manufacturer supporting Russian and CIS market enquiries for mobile hydraulic equipment. This model is used as a selection reference for agricultural, construction, lifting and municipal hydraulic systems. The complete pump marking and installation dimensions determine the configuration required for a particular machine.

Our OEM/ODM enquiries start with the original pump information and the equipment specification. A matching displacement alone does not establish mechanical interchangeability. Rotation, drive shaft, mounting flange, oil connections and operating limits must be reviewed together before ordering.

NSH100M model names and Russian markings

The Cyrillic letter М corresponds to the Latin M used in English listings. The Cyrillic suffix Л is commonly represented by Latin L. Right-hand rotation is described as правое вращение and left-hand rotation as левое вращение. These spelling variations assist identification; a rotation suffix or a different series letter changes the requested configuration.

Rotation, flange and shaft checks

Describe clockwise or counter-clockwise rotation while looking at the drive shaft end. Include the rotation arrow or nameplate photograph where available. In the reference NSH coding system, a left-hand unit carries Л, while a right-hand unit commonly has no Л suffix. Confirm the actual supplier marking because abbreviated sales descriptions may omit essential characters.

Measure the mounting flange, pilot diameter, bolt-hole spacing and overall installed length.

Record the shaft profile, spline count or key dimensions, diameter and projection.

Identify suction and pressure ports, connection dimensions and orientation.

Provide continuous pressure, intermittent duty, drive-speed range and hydraulic oil details.

The gallery shows supplier-labelled NSH100M reference photographs from several angles. They illustrate the housing, flange, oil-port connection and drive end. They do not replace an approved drawing for the quoted configuration. Shaft and interface details must be checked against the original pump and the final supply specification.

100 cm³/rev displacement and operating duty

Displacement states the theoretical oil volume moved per shaft revolution. Actual delivered flow depends on drive speed, volumetric efficiency, oil viscosity and operating pressure. For example, 100 cm³/rev at 1,500 rpm gives a theoretical flow of 150 L/min before internal leakage. This calculation is a sizing reference, not a guaranteed test result or a permitted operating speed.

Pressure ratings and speed limits must be taken from the data sheet approved for the supplied configuration. Continuous, intermittent and peak pressure are different duty conditions. The circuit relief setting, inlet conditions and drive capacity should be checked with those limits. Reference catalogue figures from another manufacturer are not automatically performance commitments for an Olive Branch Hydraulics pump.

NSH100M and NSH100A selection

NSH100M-3 and NSH100A-3 share a nominal 100 cm³/rev designation but belong to different construction families. Keep M and A letters in drawings, stock records and purchase orders. Compare mounting, shaft, oil connections, envelope and performance requirements before considering a replacement. Smaller NSH25M, NSH32M, NSH40M and NSH50M units also require their own specifications.

OEM/ODM enquiry and order confirmation

Submit the full pump marking, clear photographs and available drawing.

Review rotation, installation interfaces, oil, pressure and speed requirements.

Confirm the proposed configuration and any marking or packaging requirements.

Agree quantity, sample requirements, inspection documentation and commercial terms.

Frequently asked questions

What is the nominal displacement of NSH100M-3?

The nominal displacement is 100 cm³/rev. Delivered flow varies with speed and operating conditions.

Does NSH100 identify the complete pump?

No. NSH100 is abbreviated and can omit the construction series, version and rotation suffix. Use the full marking for configuration review.

What does the L or Л suffix mean?

It identifies the left-hand rotation version in the reference NSH coding system. Confirm rotation viewed from the shaft end.

Can NSH100A replace NSH100M directly?

Direct replacement requires checking the interfaces, dimensions, rotation and operating specification. Equal nominal displacement alone is insufficient.

Are the gallery images an approved installation drawing?

No. They are supplier-labelled model reference views. Obtain the approved configuration drawing before confirming installation.

How are price and lead time confirmed?

Price, minimum order quantity, sample terms, lead time and warranty are confirmed with the selected configuration and order quantity in the quotation.
