Single pump tubes are available in a large number of diameters from 0.0210” diameter to 0.0290”
diameter in 0.0005” increments.
Note: The number as it appears on the tube may only be represented by 3 digits, e.g. a
0.0245” tube will be represented by ‘245’.
As a guide to the tube size required if changing the tube is considered, the nominal tube sizes for
STAT
IM
5000 models as fitted during production should be as follows:
Unit / Voltage Rating Nominal Tubing
*STATIM 100 V
0.0270
*STATIM 115 V
0.0255
*STATIM 230 V
0.0245
Note: These are for aluminium boilers only. If a unit is fitted with a stainless steel steam
generator, the value will likely be in the region of a difference of 0.0040” larger. For example, a
0.0245” tube fitted to an aluminium steam generator may be 0.0285” on a stainless steel steam
generator.
If, as a result of a failed pump flow check after a filter maintenance, the tube may be changed
as follows (see Figure 12):
1. Turn the unit OFF.
2. Using a 3/8-inch wrench disconnect the pump tube (1) from the top of the steam generator
(2) or pump test bottle (6) as appropriate, and disconnect the other end from the pump outlet
fitting (3). Record the orifice diameter and discard the tube.
3. Select a smaller or larger size tube (depending on whether pump is over or under delivering).
Note: There is no prescribed formula over which diameter to select. Selection will need to
be based on perception of the under or over delivery amount.
