Fuel pump assembly

Huahui Oil Pump Nozzle Company produces and develops more than 100 kinds of fuel injection pump assemblies such as P series BQ type, PW type, P7 type, P8 type, PE type, PN type, P7100 type, P2000 type, and high-pressure common rail series.

The fuel injection pump assembly is the fuel control hub of the engine. Fuel can be injected as needed at a pressure of about 150MPa, and the injection interval error is controlled within ±0.1ms. Optimize the combustion process, increase engine power by about 10%, reduce fuel consumption, and are widely used in construction machinery, generator sets and other equipment.

 

Product Introduction

The Fuel Pump Assembly is a core component of internal combustion engines, responsible for delivering fuel from the tank to the engine at the correct pressure and flow rate. It ensures a consistent and reliable fuel supply, enabling efficient combustion and optimal engine performance. Available in mechanical and electric configurations, fuel pump assemblies are designed to meet the specific requirements of various engine types, from light-duty automotive engines to heavy-duty diesel power systems. Precision-engineered and rigorously tested, this assembly is vital for ensuring engine stability, fuel efficiency, and emissions compliance.

 

Product Advantages

Consistent Fuel Delivery: Maintains stable fuel pressure and flow to support smooth engine operation under all load conditions.

High Durability: Built with corrosion-resistant and wear-resistant materials to withstand heat, vibration, and long-term use.

Improved Engine Performance: Supports better throttle response, acceleration, and combustion efficiency by ensuring proper fuel atomization.

Versatile Compatibility: Available in various designs and specifications for gasoline and diesel engines across multiple vehicle and equipment types.

Low Maintenance: Designed for long service life with minimal maintenance, and available with integrated filters or sensors for added reliability.

 

Product Applications

Fuel Pump Assemblies are widely used across a broad range of industries and engine-powered equipment, including:

Passenger and Commercial Vehicles: Cars, SUVs, vans, trucks, and buses, both diesel and gasoline-powered.

Agricultural Equipment: Tractors, combines, irrigation units, and power tillers.

Construction Machinery: Excavators, bulldozers, road rollers, and cranes.

Industrial Engines: Generators, compressors, and factory engines using standalone fuel systems.

Marine Engines: Inboard and outboard diesel engines for small to mid-sized boats and vessels.

 

FAQ

100 pieces

 

What does a fuel pump assembly include?

It typically includes the pump unit, electric motor or mechanical drive mechanism, pressure regulator, and sometimes a fuel filter or level sensor.

 

How do I know if my fuel pump is failing?

Common signs include engine stalling, difficulty starting, loss of power, poor fuel economy, and unusual noises from the fuel tank area.

 

Can a fuel pump be repaired or must it be replaced?

Some issues, like clogged filters, may be resolved without full replacement, but most fuel pumps are sealed units and are replaced when faulty.

 

Is the fuel pump assembly the same for diesel and gasoline engines?

No, diesel and gasoline engines require different pump designs and pressure specifications. Be sure to choose the correct type for your engine.

 

How long does a fuel pump typically last?

Under normal conditions, a fuel pump can last between 100,000 and 200,000 kilometers, or several thousand operating hours in industrial use.
