Nanyue Hengyang B6PN960 Diesel Injection Pump – 144 KW Inline Power For Weichai Gensets & Industrial Engines

For many Weichai-powered generators and industrial units, the "heart" of the fuel system is a Nanyue (Hengyang) B6PN960 inline injection pump. In export documents it's clearly described as a 144 kW diesel injection pump, model B6PN960-BH6PN120R, engine spare part No. 13067688, supplied for generator and diesel engine applications.  

This listing presents a professional, OE-pattern replacement pump for workshops and distributors who want a ready-to-install solution instead of rebuilding a worn core.

 

 

The code B6PN960 identifies a mechanical inline fuel injection pump from Nanyue Hengyang, a well-known Chinese manufacturer of high-pressure diesel pumps. In shipping and catalog data it is consistently tagged as:

"INJECTION PUMP 144 kW, M: NANYUE, MOD: B6PN960-BH6PN120R" 

Used as a diesel engine spare part for 144 kW-class engines, often Weichai generator sets and similar industrial power packs. AliExpress+1

The B6 prefix indicates a six-plunger design, making it suitable for 6-cylinder engines that need accurate, mechanically timed fuel delivery under tough duty cycles.

 

 

You can confidently position the Hengyang B6PN960 pump for:

Weichai generator sets around 144 kW output – where export descriptions explicitly pair the pump with 144 kW engines 

Industrial and construction machines using Weichai or similar 6-cylinder diesels in the same power range (compressors, drilling rigs, small marine units, pumps).

Replacement market for Nanyue / Hengyang B-series pumps where the original pump model on the dataplate is B6PN960 or B6PN960-BH6PN120R.

If your existing nameplate matches this code, this unit is intended as a direct bolt-on replacement.

 

 

Rather than generic "good quality" claims, emphasise what buyers care about:

✔ OE-pattern geometry
The body, camshaft drive, governor interface (BH6PN120R assembly) and mounting points follow the original Nanyue layout, allowing the pump to drop onto engines configured for B6PN960 without bracket modifications. 

✔ Six precisely matched elements
Each plunger-and-barrel pair is honed as a set to restore the sharp pressure rise and tight delivery tolerance that 144 kW-class engines need for clean combustion and fuel efficiency.

✔ Robust mechanical control
A mechanical inline pump is still the favourite in many remote locations: no ECU, no delicate electronics, just camshaft-driven plungers and a mechanical governor that will happily work in heat, dust and high-sulphur fuel environments.

✔ Ready for export fleets
The B6PN960 appears regularly in international trade records as a diesel engine spare part under fuel-pump HS codes, demonstrating its acceptance in overseas generator and truck markets.

 

You can present the essentials in a clear, SEO-friendly block:

For Google visitors who are technicians or parts managers, a concise procedure builds trust:

Verify pump code
Confirm the old pump dataplate reads B6PN960 (or B6PN960-BH6PN120R) and that power and rotation match your engine.

Prepare the engine
Lock the engine at the correct timing position and mark existing fuel-line positions before removal.

Swap the assembly
Remove the old Nanyue pump, transfer any external fittings if required, and mount the new B6PN960 using fresh gaskets and O-rings.

Calibrate fuel settings
Ideally, run the pump on a test bench to set delivery curves, then fine-tune idle and full-load settings on the engine according to the manufacturer's data.

Final checks
After start-up, confirm:

Smooth cold and hot starting

Clean exhaust with minimal black smoke under load

Stable frequency / rpm on generator sets.
