Port and Helix pumps are most often used in maritime diesel engines due to their simplicity, trustworthiness, and its capacity to be scaled up in proportion into the motor dimensions.[4] The pump is comparable to that of a more info radial piston-kind pump, but in lieu of a piston it has a machined plunger which includes no seals.
