The 275 Series Electric Actuator is a second generation design more powerful than its predecessor. It is for Bosch-Style "P" 3000-7000 fuel injected Pumps. Coupling the 275 Series with a fuel pump results in a high performance fuel control system without external linkages or brackets. Two isolated chambers eliminates the possibility of any magnetic particles collecting and jamming the actuator. As a result, the 275 Series typically outlasts the life of a diesel engine and is maintenance-free. Camshaft bearing retainer kits, position feedback transducer and heavy duty bearing retention options are available.
