pump or motor The actual height may be less NOTE Hmax in Table is the maximum permitted height The actual dimension H may be less The values Hmax given for each pump size take into account the maximum height for the greatest given baseplate number and the centre-line height of the pump or motor, whichever is the greater NOTE On the left side of the bold line in Table 2, the centre-line height of the pump is the greater; on the right side the centre-line height of the electric motor is the greater NOTE Additional sub-structures, for example feet for free-standing installations, vibration dampers, are not included in the dimensions Hmax and hmax NOTE Figure shows the locations for five holes (A, B, C, D and E) Baseplates may have either four (A, B, C and D) or three (A, C and E) holes
