They are pre-detremined volumetric injectors that ensure each lubrication point receives the proper amount of lubricant. Which means there is no worry about over or under lubrication. FUNCTION The ZDM series are classic PDIs. Reliable, Accurate. As pressure builds in the manifold, the piston in the injector fires forward, discharging a set amount of lubricant to the lubication point.. As the pressure is relieved, a compression spring returns the piston to its original position. This movement recharges the injector with more lubricant and the injector is now ready for the next cycle. The ZDM series injector allows for injectors to be mounted directly onto the lubication point and are available with push–to–connect fittings which reduces installation labor costs. It is important to note that the lubricating pump used in the system with the ZDM distributor must build pressure to 15 bars (220 psi) at the injector in order to actuate injector discharge. The recommend operating pressure is 21bar (300 psi). A pressure relief valve is also required to quickly drop the line pressure to between 0.3 to 0.7 bar (5 to 11 psi) range between lubrication cycles. This allows the injector to fully recharge.
