Nanjing Yalong Petrochemical Equipment Technology Co., Ltd. has successfully completed the manufacturing, inspection and shipment of four sets of high-pressure water injection pumps for an energy project in Kazakhstan.
Designed for demanding oilfield and industrial applications, these pumps feature a maximum outlet pressure of 50 MPa and a flow capacity of 12 m³/h, providing stable and reliable high-pressure water injection performance. Before delivery, all pump units underwent strict quality inspections and were securely packaged for international transportation.
High Pressure Reciprocating Pump for Water Injection Applications
Water injection is an important technology widely used in oilfield production to maintain reservoir pressure and improve oil recovery efficiency. The reliability of the injection pump directly affects the stability and efficiency of the entire production system.
The supplied equipment adopts a high-pressure reciprocating pump structure, which uses the reciprocating movement of plungers to deliver water at high pressure. Compared with conventional pump types, reciprocating pumps are suitable for applications requiring high pressure, stable flow output and continuous operation.
These pumps are mainly used for:
- Oilfield water injection systems
- Reservoir pressure maintenance
- High-pressure water transportation
- Petroleum and petrochemical processes
- Industrial fluid injection applications
Technical Specifications of the Water Injection Pumps
According to the equipment nameplate, the main parameters of the supplied pumps include:
| Item | Specification |
|---|---|
| Pump Type | Q290-12/50 |
| Pump Type | High Pressure Reciprocating Pump |
| Outlet Pressure | 50 MPa |
| Capacity | 12 m³/h |
| Plunger Diameter | 39 mm |
| Stroke Length | 89 mm |
| Pump Speed | 377 rpm |
| Motor Power | 200 kW |
| Fluid Temperature | ≤60℃ |
| Weight | Approx. 3,900 kg |
With a robust reciprocating design and high-pressure capability, the pumps are suitable for continuous operation in harsh industrial environments.
Four Pump Units Manufactured for Kazakhstan Project
A total of four sets of water injection pumps were manufactured and delivered for this project. Producing multiple pump units for one project requires strict consistency in machining accuracy, assembly quality and performance control.
During manufacturing, Nanjing Yalong carried out detailed inspections of key components, including the pump body, plunger system, sealing components and connection interfaces. These quality control procedures help ensure reliable installation and long-term operation at the customer's site.
Strict Quality Inspection Before Shipment
Before shipment, each pump unit was inspected according to the project requirements. The inspection process focused on:
- Main pump components and assembly condition
- Pressure-bearing parts verification
- Plunger and sealing system inspection
- Connection dimensions checking
- Overall equipment appearance inspection
- Export packaging confirmation
Through systematic quality control, Nanjing Yalong ensured that all four high-pressure reciprocating pumps were ready for safe transportation and commissioning.
Secure Export Packaging for International Delivery
High-pressure industrial pumps contain precision components that require professional protection during long-distance transportation.
Before shipment to Kazakhstan, each pump was properly protected against moisture, dust and mechanical impact. The equipment was securely fixed and packed according to export transportation requirements to ensure safe delivery to the project location.
