Engineering Features

 

Compact Integrated Skid Design
The pump, cryogenic piping, valves, and process interfaces are mounted on one structural skid, reducing installation work and minimizing required foundation space for projects with limited site area.
Stable Cryogenic Liquid Delivery
The submerged pump operates continuously in LNG, maintaining stable discharge pressure while reducing vapor generation during liquid transfer.
Reduced Installation Time
Factory-installed piping, wiring, and instrumentation simplify onsite work, allowing contractors to complete installation with only process, electrical, and control connections.
Easy Equipment Maintenance
The open skid layout provides direct access to the pump, valves, and instruments, allowing routine inspection and replacement without dismantling surrounding piping.
Flexible System Integration
Connection interfaces, electrical configuration, and instrumentation can be adapted to match new installations or existing LNG station layouts.

FAQ

 

Q: How do I select the correct pump capacity for my LNG station?

A: Pump capacity is determined by dispenser quantity, expected hourly throughput, storage tank pressure, and required discharge pressure. Our engineers can recommend an appropriate configuration based on your station design.

Q: Can this skid replace an existing LNG pump skid without major piping modifications?

A: In most projects, yes. The skid can be designed with matching process connections, flange standards, and interface dimensions to simplify replacement work.

Q: What site conditions are required before installation?

A: The installation area should have a level concrete foundation, electrical power supply, grounding, and compatible LNG process connections. Detailed installation drawings are provided before shipment.

Q: Is operator training provided after equipment delivery?

A: Technical documentation, operating procedures, and remote commissioning support are available. On-site technical assistance can also be arranged for selected projects.

Q: Which spare parts should be kept in stock?

A: Recommended spare parts typically include seal kits, sensors, valves, pressure transmitters, and electrical components commonly required for preventive maintenance.

Q: How often should the skid be inspected?

A: Routine inspection intervals depend on operating conditions. Most projects perform regular checks on valves, instrumentation, electrical systems, and pump performance according to the maintenance manual.

Q: What information should be provided when requesting a quotation?

A: To recommend a suitable configuration, buyers typically provide LNG flow rate, required discharge pressure, storage tank capacity, installation location, power supply, hazardous-area classification, and control system requirements.
