In 2016 the pump manufacturer ESPA updated its residential pool range and changed the name of its pumps.
The ESPA SILEN pump range became the ESPA SILEN S pump range.
The dimensions and hydraulic performance of the ESPA SILEN and ESPA SILEN S pumps are the same.
The suction fitting of the Silen S has been increased from 50 mm to 63 mm, so the manufacturer has added an adaptor fitting from 63 to 50 mm.
This fitting means that the old pump cannot be unscrewed and the new pump cannot be screwed on, so a piece of pipe must be cut to fit the new adapter fitting.
The product images show the differences between the old and new pumps and the installation process of the Silen S.
The following box details the relationship between old and new models:
Since a change in the installation must be made with the Silen S model, Espa used the mould of the old Espa Silen pump to make the NOX range that we leave below.
It has the same dimensions, hydraulic performance and fittings as the Silen, so it is totally interchangeable.
The manufacturer only made the NOX range of the single-phase models from the Silen 75 to the 150.
