Nanjing Yalong Petrochemical Equipment Technology Co., Ltd. has successfully completed the manufacturing, inspection and shipment of 415Q-5 quintuplex plunger pumps with aluminum bronze liquid ends for a project in South America.
The pumps are designed for demanding high-pressure fluid handling applications where stable pressure output, reliable continuous operation and corrosion resistance are important. After production and factory inspection, the equipment was prepared for international transportation to the customer's project site.
Aluminum Bronze Liquid End for Demanding Fluid Applications
One of the key features of this project is the use of an aluminum bronze liquid end.
The liquid end is the part of the pump that comes directly into contact with the process medium, making material selection especially important when corrosive or aggressive fluids are involved.
Aluminum bronze offers several advantages for selected industrial applications, including:
- Good corrosion resistance
- Strong mechanical performance
- Good wear resistance
- Reliable operation in demanding environments
- Suitability for selected brine, seawater and chemical fluid applications
For projects involving corrosive media, choosing the right liquid end material can help improve pump reliability and service life.
Technical Highlights of the 415Q-5 Quintuplex Pump
The supplied unit is a 415Q-5 quintuplex plunger pump with a 5-inch stroke.
According to the equipment nameplate, the pump has a rated maximum input of 415 HP at 400 RPM. Different plunger sizes can be selected to achieve different combinations of flow capacity and discharge pressure.
Key examples include:
- 4.5" plunger: 688 GPM at up to 935 PSI
- 4.0" plunger: 544 GPM at up to 1,180 PSI
- 3.5" plunger: 416 GPM at up to 1,545 PSI
- 3.0" plunger: 306 GPM at up to 2,100 PSI
- 2.5" plunger: 212 GPM at up to 3,025 PSI
- 2.0" plunger: 136 GPM at up to 4,730 PSI
- 1.875" plunger: 120 GPM at up to 5,000 PSI
This flexible plunger configuration allows the pump to be matched with different pressure and flow requirements for oilfield, petrochemical and industrial applications.
Quintuplex Structure for Stable High-Pressure Delivery
The 415Q-5 adopts a quintuplex reciprocating structure, using five plungers to deliver fluid under pressure.
Compared with simpler reciprocating configurations, the quintuplex arrangement can help provide smoother flow output and lower pressure pulsation, making it suitable for applications requiring stable and continuous high-pressure delivery.
Typical applications include:
- Oilfield water injection
- High-pressure fluid transfer
- Chemical injection
- Brine and saltwater pumping
- Petroleum and petrochemical processes
- Industrial high-pressure pumping systems
Built Around Project Operating Conditions
Selecting a high-pressure plunger pump requires more than choosing a pump model.
Important project parameters normally include:
- Required discharge pressure
- Required flow capacity
- Fluid composition
- Corrosiveness of the medium
- Operating temperature
- Suction conditions
- Continuous or intermittent operating mode
- Liquid end material
- Sealing requirements
- Installation environment
For this South American project, the use of an aluminum bronze liquid end was selected to better match the fluid and operating conditions.
Factory Inspection Before Shipment
Before delivery, the 415Q-5 quintuplex plunger pumps underwent factory inspection to verify manufacturing quality and shipment readiness.
The inspection process included:
- Main pump component inspection
- Aluminum bronze liquid end inspection
- Plunger and sealing component checks
- Connection dimension verification
- Assembly quality inspection
- Equipment appearance inspection
- Export packaging confirmation
These procedures help ensure that the pump is properly prepared for installation and operation after delivery.
Shipped to South America
High-pressure reciprocating pumps require reliable protection during long-distance international transportation.
Before shipment, the equipment was securely fixed and protected against moisture, dust and mechanical impact. Important openings and connection points were also sealed and protected according to export transportation requirements.
The completed shipment represents another international project delivery for Nanjing Yalong in the South American market.
