These pre-lubrication metering devices provide flexible options of delivering precise and controlled lubrication outputs which meet exact requirements for diverse applications such as bearings, bushings, pins and slides that help ensure each lubrication point receives the proper amount of lubricant. Which means you won′t have to worry about over or under lubrication.
Pre-lubrication metering device = Direct injector (pump pressure dispenses lubricant to the lube point)
 

Area of application

Pre-lubrication distributors are used in applications where the lubricant needs to be delivered to the lubrication point immediately. Especially in the case of long lubrication point lines and high bearing back pressures, increasing the pressure in the main line can provide reliable lubrication of the bearing, as the expelling pressure approximately equals the pressure in the main line. Fields where pre-lubrication distributors are widely used is with machine tool, textile, and packaging machine lubrication.
Pre-lubrication single piston distributor with aluminum manifold can provide different outputs per customer’s requirements. They distribute and meter the lubricant fed by an intermittently operated centralized lubrication pump unit in iSHAN & SMUS single- line centralized lubrication systems. In each lubrication cycle, a precisely metered quantity of lubricant, ranging from a minimum of 0.03 c.c. to a maximum of 0.5 c.c., is fed to the connected lubrication points.
 

Remark

1. Grease permissible range from NLGI grade No.0 to No.1 at ambient temperature 40℃.
2. Output volume & max. operating pressure based on NLGI grade No.0 of grease.
