Pedrollo 4SR1/13 hydraulic part:

The Pedrollo 4SR1/13 is a 4'' (Ø 98mm) hydraulic well pump part, fully executed in stainless steel AISI 304 and technopolymer impellers. The Pedrollo 4SR1/13 hydraulic part is suitable for 4'' Pedrollo or Franklin electric motors of 0.5HP.

The 4SR1/13 is equipped with a floating axial multi impeller system and can pump up to 150 grams of sand per m3 (medium). Maximum medium temperature 30 °C.

This hydraulic part has a 1¼'' pressure connection and a maximum pump capacity of 1,200 ltr/hour and a maximum head of 5.1 Bar.
Pump curve Pedrollo 4SR1/13:

Capacity (Ltrs/min) - head (Bar)

20 L/min. - 5.1 bar


The 4SR1/13 has a 1¼'' pressure connection, for a good coupling – transition to a Tyleen hose, we recommend mounting the Beulco coupling with 1¼'' 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 4SR1/13 requires an engine power of 0.5 HP / 0.37KW. in a 230v. or 400v. performance.

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