Single-line parallel. This system is easy to design, install, maintain, modify or expand. It typically operates at high fluid pressures and can be used with grease or oil. In this system, the pump pressurizes the main supply line, and a piston inside the primed injector displaces a premeasured amount of lubricant through the outlet to the bearing. The pump turns off and the supply line pressure is vented back to the reservoir. The spring-loaded piston returns to rest and the discharge chamber fills with a measured charge of lubricant for the next cycle.
