As technology continues to evolve, so too do the tools and equipment we use in our everyday lives. In the world of diesel injection pumps, this evolution is evident in the development of Zexel camshaftless pumps. These unique devices come in three different sizes: PFR..KX, PFR..KD, and PFR..MD. Understanding the differences between these sizes can be crucial to ensuring optimal performance and fit for your specific application.
Shared Mounting Schema, Different Heights: PFR..MD and PFR..KD
While the PFR..MD and PFR..KD share the same mounting schema, they differ significantly in their heights. This means that while the method for installing these two sizes is the same, their physical vertical dimensions vary. This difference in height impacts on the camshaft and spacer required for running the pump on the cam box.
Same Height, Different Mounting Schema: PFR..KX and PFR..KD
On the other hand, the PFR..KX and PFR..KD sizes share the same height, meaning their vertical dimensions are identical. However, their mounting schemas differ. This variation in the installation methods affects the fact that it is necessary to choose the appropriate mounting plate between these two pump sizes.
Different Plunger Lift and Bore Pitch: PFR..MD and PFR..KD
Lastly, it's important to note the differences between the PFR..MD and PFR..KD sizes regarding the plunger lift and the distance between the centerline of a cylinder bore to the centerline of the next cylinder bore adjacent to it. These variations can have significant impacts on the selection of the appropriate camshaft for your specific application. Understanding these differences will help ensure the appropriate configuration of the cam box.
In conclusion, it is paramount to grasp the distinct characteristics of Zexel camshaft-less pumps to make an informed decision on the suitable configuration for the Marbed 9562-M1 universal cam box during the testing process. A careful consideration of various factors, including mounting schemas, heights, plunger lifts, and bore pitches, is instrumental in setting up the cam box correctly to effectively test these pumps.
The modular cam box is designed to accommodate many different types of camshaft-less pumps and can be applied to any test bench for diesel fuel injection pumps. The ability to test up to 11 types of immersed pumps, including those produced by Bosch, Zexel, Denso, and others, further demonstrates the versatility of the system.
