This standard specifies the basic dimensions of the base and installation of axial suction centrifugal pumps. In order to be suitable for various installation conditions, this standard gives the positions and numbers of holes for fixing the base that can be freely selected. This standard is mainly applicable to the connection dimensions of axial suction centrifugal pumps that meet GB5662-85 "Marking, Performance and Dimensions of Axial Suction Centrifugal Pumps (16bar)" and motors with base feet. The motor size should comply with the provisions of JB3074-82 "Technical Conditions for Y Series (IP44) Three-Phase Asynchronous Motors (H80~280mm)". Other types of pumps may also adopt this standard if appropriate. This standard is equivalent to the international standard IS036611977 "Axial suction centrifugal pump base dimensions and installation dimensions". The base number and dimensions shall comply with the provisions of the figure and Table 1. The basic installation dimensions shall comply with the provisions of Table 2. The base size is found from Table 2 according to the pump size mark and the corresponding motor base number. Then, the size of the base number is found from Table 1. Table 1 Base number and size

Note: ① m is the maximum allowable height of the base, which includes the thickness of the gasket that may be placed between the base and the pump motor. The actual height can be less than this value.
② The dimensions mx and m do not include additional bottom structural parts, such as the height of the foot of an independent device, the alarm, etc. ③ The positions of five holes (A, B, C, D, E) are marked in the figure. The base can also have four (A, B, C, D) or three holes (A, C, E), which is determined by the pump manufacturer.
