Pump curve Pedrollo 4SR8/23:
Capacity (Ltrs/min) - head (Bar)

40 L/min. - 15.0 bar
80 L/min. - 14.1 bar
100 L/min. - 13.4 bar
140 Ltr/min. - 11.1 bar
200 L/min. - 5.3 bar


The 4SR8/23 has a 2'' pressure connection, for a good connection – for a transition to a Tyleen hose we recommend mounting the Beulco coupling with 2'' male thread in the pressure connection of the pump part.

If you use tyleen / PE 100 pipe, we advise you to use the separate Beulco conical bush in combination with the Beulco coupling, so you are assured of an optimal transition to your PE pipe.

The 4SR8/23 requires an engine power of 5.5 HP / 4.0 KW. in a 400v. performance.

For matching motors see Pedrollo or Franklin 4'' electric motors (see below under related products).
