Installation 

The SaniMidget SB clip-on versions are installed on either a 1” BPE US down pipe (16B132-xx) or a 
1½” BPE US down pipe (16B182-xx). The SaniMidget SB weld-on versions are installed on either a 1” 
BPE US down pipe (16B233-xx), a 1”ISO down pipe (16B232-xx) or a DIN Range 1 Ø28 down pipe 
(16B132-xx).  
 
Correct down-pipe dimensions are important to ensure volumetric flow rates as provided in this manual. 
Clip-on hole centre for 1” must be less than 15 mm (0.59”) from the bottom end (recommended 13-15 
mm – 0.51”-0.59”) of the down-pipe and for the 1½” less than 34 mm (1.33”) from the bottom end 
(recommended 30-34 mm – 1.18”-1.33”). For weld-on versions NO clip hole is needed – the connector 
(containing the clip hole) is welded on the end of the down pipe. 
 

Important 

information: 

SaniMidget SB/3-A weld-on versions: 

To continue to meet the requirements of the 3-A Sanitary Standard 78-01, the weld-
on version shall be welded onto the end of a straight down pipe. This straight down 
pipe shall be connected to the supply system in a dismountable manner. This shall 
allow for easy disassembly and reassembly (e.g. a sanitary clamp coupling) to allow 
visual inspection (through the down pipe) of the inside of the down pipe and the 
inside of the connector. Welding must be performed according to relevant 3-A 
Sanitary Standard. 

 
The SaniMidget SB itself is assembled as follows (for the weld-on version, weld the connector onto the 
down pipe as explained above): 
 

1.  Insert the cylindrical end of the stator (Pos. 3) through the Rotor (Pos. 2).
