6.4 GD2 values

7 Spare parts
The GD2 values of complete pump consists of GD2 of pump
(fig. 39) + n x GD2 of intermediate shaft (fig.40) Table (Fig.41) gives the list of recommended spare parts
+ GD2 of drive shaft (fig 40) + GD2 of coupling for 2 years operation. (For 5 years operation the quantity
can be considered as double of that of following table)
