Bijur Delimon - Zem Injector


The ZEM Series injector line are positive displacement injectors (PDI) that deliver precise and controlled lubrication outputs which meet exact requirements for diverse applications. They are pre-fixed volumetric injectors 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.


ZEM Series injectors are classic PDIs. Reliable. Accurate. As pressure builds in the manifold, the piston in the injector moves forward, discharging a set amount of lubricant to the application point. As the pressure is relieved, a compression spring returns the piston to its original position. This movement recharges the injector with more lubricant. The injector is now ready to be fired again.


  • Handles oil and soft greases
  • Multiple output volumes for diverse application types and points
  • Modular design allows different outputs within a single manifold
  • Can be used in the same system with other ZEM series injectors
  • Optional push-to-connect fittings help reduce installation labor costs

It is important to note that the lubricating pump used in the ZEM Series injectors system must build pressure to 15 bar (220 psi) at the injector in order to actuate injector discharge. The recommended operating pressure is 21 bar (300 psi). Also, a pressure relief valve is required to quickly drop the line pressure to the 0.3 to 0.7 bar (5 to 11 psi) range between lubrication cycles. This allows the injectors to be fully recharged.

ZEM 32 and 33 Series injectors are used in conjunction with manifolds or tee fittings. Other ZEM Series injectors are manufactured with multiple outlet manifolds. All ZEM injectors are available with either a compression style or push-to-connect outlet fitting.

Note: Manifold part numbers are shown on page 4 and 5.
* Requires manifold or tee fitting, sold separately.


Bijur Delimon - How to Order Zem Injector

ZEM injectors use a smart part numbering system that allows you to tailor the injector to meet your needs. First, choose the injector type, number of outlets, outlet type and the discharge volume for each outlet. Then, put the numbers into the corresponding squares in the easy-to-use grid.

Example: To order a three outlet, 35 Series injector, with push-to-connect fittings, where the discharge volumes are 0.1cc, 0.2cc and 0.6cc, you would use Part #ZEM353PDFH.
