FSA Resistive Injector at Lubrication Point
An FSA resistive grease point injector is a metering device used in progressive or resistive automatic lubrication systems, designed to deliver a precise amount of grease or oil directly to an individual grease point. It operates using an internal resistor that regulates the flow rate according to the system pressure, ensuring a constant and controlled supply of lubricant.
Main features:
The resistive injector is installed in an oil-lubricated system. It can be mounted on single-sided or double-sided lubrication strips, or directly at the point to be lubricated. For proper operation, the line pressure should not be less than 2 bar and should not exceed 15 bar.
This injector incorporates a non-return valve to maintain residual pressure during intervals, a filter to prevent contaminants in the bearings, and a metering shaft. When the pump is operating, oil reaches the shaft, and the injector's discharge is determined by the shaft's dimensions. The discharge and flow direction are indicated on the injector body.
The injector can be mounted on rails or directly on the lubrication point. It is recommended to use one injector per lubrication point, depending on the machine's requirements. Installing an auxiliary filter in the main line prevents impurities from clogging the injector.
