The innovative design of DCSS 39/50 features a single impeller with two parallel rows of turbine blades. Designed for high performance engines. The blades carry two high-pressure pump channels as opposed to a conventional one-stage pump, which uses a single impeller with a single row of blades at the outer edge.

This innovative design results in improved hot fuel flow as well as minimal noise and power consumption, resulting in an efficiency that is 20 percent higher than conventional pumps.
