INTERNATIONAL STANDARD ISO 3661-1977 (E) End-suction centrifugal Pumps - Baseplate and installation dimensions 1 SCOPE This international Standard specifies the basic baseplate and installation dimensions for end-suction centrifugal Pumps. Alternative numbers and locations of baseplate fixing holes are given to suit individual installations. 2 FIELD OF APPLICATION The dimensions and other data given in this International Standard are intended primarily for use with centrifugal Pumps in accordance with ISO 2858, coupled to foot- mounted electric motors for installation on a foundation. Where suitable, this International Standard may be used for other types of pump. 3 REFERENCES ISO/R 273, Clearance holes for metric bolts.
