Installlation nstructions
Preservation:
1 Shaft outside diameter is within tolérance 0 comm
2.Shaft run out<0.1mm
3.Shat end float<0.13mm
4 No sharp edges on the shaft over the o ring
Note:
During the installation don’t scratch or damage the o ring . if anything is damaged , please contact with our local agents to replace a new one.
Installation in structions:
The full set of cartridge seal is cleaned and exactly passed leakage examine before sale.In order to avoid damage, don’t disassemble and clean the parts again before fixing.
2 The fitting allowance between the seal and shaft is dl h6 0.8, and there should be leading-inedge at the end of shaft. The outside diameter of shaft at the position of screw should be 01 -0.2mm smaller, resisting the screw over-tighten Lubricate the shaft with oil.
3. Place the cartridge seal into the pump chamber, then:
A: Tighter four screw bolts of flanges, ensuring the medium leading in hole”Gat the top Position.
B: Tighter four set screws and position the shaft sleeve on the shaft.
C: Remove four gauge plates. Please keep them and they will be used in future installation and dissassembl.
D Connect the medium lead-in pipe with hole”Gin order to flush away the friction heat and flushing the seal chamber when pump running.
Note:
After complete the installation, turning the shaft by hand to check for the rotation. If the shaft could not rotate smoothly, seal had been improperly installed.
