1 - STEPS TO BE FOLLOWED PRIOR TO PUMP DISASSEMBLY Should pump repairs be required, it is recommended to acquire full familiarity of the procedures to be followed by studying these instructions and the “Operating Manual for Centrifugal Pumps”. FOLLOW THE SAFETY INSTRUCTIONS LISTED UNDER CHAPTER 2 OF THE AFORE MENTIONED OPERATING MANUAL.

For more information and the assembly dimensions pls contact POMPETRAVAINI or its closest representative. Clean the stationary seal element removing encrustation, oxidation and deposit of the flushing liquid. Lubricate the seat and the elastomers of the stationary seat with oil that is compatible with the seal elastomers.

install the seal cover VDMA 471 on the shaft, the cooling cover VDMA 165 with the studs in place, then all the required gaskets and the pre-assembled shaft sleeve. Prior to finalise the mechanical seal assembly, already fitted on the shaft sleeve, it is recommended to clean both seal faces with a clean and soft tissue.

Specify also the VDMA number of the required part, as seen on the pump sectional drawing and parts list for proper identification of spare parts. We recommend the use of original spares: in case this is not respected, POMPETRAVAINI declines any responsability for eventual damages caused by not original spare parts.
