Type DT-STP submersible turbine pumps lift fuel from the underground tank to every dispenser on the forecourt — with the leak detection, shut-off and connection parts that complete the installation.
One submerged pump feeds every dispenser on the island. The motor end sits inside the tank, the discharge head carries the manifold — a single unit serves up to 8 nozzles.
Electric-motor-driven centrifugal pump, fully submerged in the tank and connected to the discharge head by a coaxial column pipe. For diesel, kerosene, gasoline and alcohol fuel blends.

Five working parts around the pump — detect leaks, protect the intake, connect the pipework and shut the line down when something goes wrong.
Sits on the pressure line between pump and dispenser. Restricts flow to under 11.4 L/h when a line leak is detected.
