2. Coupling
> We can't remove coupling of the pump even if we loosen the hexigonal setscrew.
> Why can't we remove ?
> Please inform me the instruction manual.
- Remove by hydrolic from factory.
Normally, the coupling shall be changed at site.
If can not remove at site, could you send me the drawing ?
> 3. Grease
> Have this pump already refilled the grease before shipment?
- We have fill full for grease already
Could you inform me your recommanded grease brand and type and
how often can we refill or add the grease ?
In the manual it is not described.
> 4. Torelance of shaft
> Please inform me the torelance of the shaft of the pump.
> * This means the torelance of installation of shaft centering.
- No torelance of shaft because we have baring for support.
I can't understand what you mean "No torelance".
The torelance means allowance of difference of centering of coupling.
Normally, ± *** . ** mm .
Please inform it.
