ZEE Distributor
The ZEE lubricant metering elements are designed for single - line centralized lubrication systems. The quantity of lubricant to be metered is delivered after each pressure stroke. Its metering is precise. With this distributor, there is no dripping, it can be install at any position and it is free of wear.
Operation
The metering elements are fixed on the manifold. During the pressure stroke the ball is lifted from its seat in the housing and pushed up to the top against the spring force, and at the same time the non-return valve is lifted against the spring pressure thus discharging the lubricant to the greasing points.When pressurising the non-return valve closes first. The relief valve of the pump maintains a residual pressure of 0.8 bar in the main line. Against this pressure the ball is returned to its end position by spring. The lubricant which remains in front of the ball is being returned to the chamber, ready for the next cycle. The time for re-charging the lubricant is mainly determined by the operational viscosity, discharge volume and other factors. The necessary interval between two cycles ranges from 0.13 to 30 sec.
