Resistive injectors for lubrication systems. Buy online at the best price
The resistive injector or resistive dispenser is used in lubrication systems that work intermittently and can be mounted on either side or double distribution strips and directly at the lubrication point. For the system to work in optimal conditions, it must have a pressure of 2 to 15 bar. Other pressures are not recommended for the resistive lubrication system. These injectors have and must select the determined and fixed dosing volume in each impulse so that they dispense a certain volume of lubricant, they are not adjustable, their output flow is fixed.
This injector incorporates a check valve in order to maintain the residual pressure during the intervals, it also incorporates a filter to prevent any type of contaminant that may reach the bearings and a dosing shaft. When the pump works, the lubricant reaches the shaft and discharges, depending on the dosage size, it will dose a volume of lubricating oil.
The resistive injectors have a small arrow marked on the body, which indicates the direction of lubrication, since as they can be placed on a strip or directly at the lubrication point, it helps us select it.
It is recommended to place an injector for each lubrication point, since if it is not used in this way the dosage volume will not be correct and it would not lubricate enough and we could have a breakdown.
The standard threads of these resistive injectors are 5/16” and 1/8” and oval nuts are usually placed at the outlet to attach to the pipe that leads to the Lubricationpoints. However, there is a type of injector in which the tube is inserted instantly and automatically. Resistive injectors are used in any industry where a lubrication system is required.
