Make Refuel More Efficient

Submersible Turbine Pumps utilize turbocharging technology to pressurize fuel above atmospheric pressure. Utilizing pressure, the pump pushes fuel through the pipeline directly to the dispenser. Due to its natural operating characteristics, this series is safe, energy-saving, and designed to create higher economic benefits for fuel stations. Trusted globally, Submersible Turbine pumps have been successfully applied in 100,000 fuel stations around the world since the 1960s.

The complete and extensive product series includes standard, smart, and high-flow models to meet diverse customer needs. It delivers maximum flow rates ranging from 200 L/min to 1000 L/min, with power ratings spanning from 0.75 HP to 5 HP. The series is widely compatible with diesel, gasoline, kerosene, various gasoline mixtures, ethanol, and methanol. It can support high-precision mechanical or electronic pressure leak detectors, as well as variable output options.

Key Characteristics & Structural Design

Optimized Flow Design: The streamlined oil head design minimizes inlet fuel pressure loss and maximizes efficient flow rates.
Easy Maintenance: The integrated packer head features a built-in link and junction box. This design eliminates external wiring devices, greatly simplifying equipment installation and commissioning. Additionally, the entire extractable pump and motor assembly is lightweight and equipped with an assisted extraction mechanism.
Spill Prevention: Fuel automatically flows back when pulling out the packer head and motor assembly. This mechanism prevents fuel spillage effectively.
Safe Servicing: The packer head integrates all connecting components, making installation and maintenance simple and safe. The liftable check valve also facilitates line pressure relief, preventing fuel spills during dispenser maintenance.
Flexible Pipeline Layout: The packer head outlet allows for both horizontal and vertical fuel discharge, making pipeline layout and construction much more convenient.
Vacuum System Support: Features an easy-to-clean independent vacuum heat transmitter system, pre-configured with two intake ports.

Mechanical Leak Detector

Accurate, Safe, and Eco-Friendly

Submersible Turbine pumps feature a mechanical leak detector with a unique structure and an extended service life. To meet different fueling requirements, it is available in dedicated gasoline and diesel modes. It maximizes station profitability while ensuring safe and eco-friendly operations.

Instruction Guidelines:

All detector models can detect a leak of 11.4 L/h under a pressure of 10 psi.
When a leak occurs, the flow rate of all models will be restricted to less than 11.4 L/h.
After a nozzle is lifted, the testing cycle for all detector models takes approximately 2 to 3 seconds.
All detectors begin operating once the pipeline pressure rises above 1 psi.
All models can detect leaks within 3 meters of the detector installation position.
When pipeline pressure drops below 3 psi, all detector models will close.
