SL-PVDF:
For transfilling and draining of drums and containers.
The perfect drum pump for the most thin liquids.
Version A for high flow rate,
Version R for high pressure, with foot valve for complete drainage.

Recommendation:
For heavy liquids the strong motor p400-A.

SL-PVDF-S:
The feed screw (S) is dedicated for liquids of medium viscosity (η > 200 mPas), if
the impeller types A and R reach their limitations.
With induction motor ideal combination for gentle dealing with the liquid.

Recommendation:
Induction motor with frequency inverter, for variable flow rate.
