GRUN DRUM PUMPS - POLYPROPYLENE TUBE
SL-PPFor transfilling and draining of drums and containers, SL-PP is the perfect drum pump for the most thin or aggressive* liquids.
Version A for high flow rate,
Version R for high pressure, with foot valve for complete drainage.
Recommendation: SL-PP-R-HC with motor p400-A.
*with drive shaft hastelloy C (HC) there are no problems with aggressive liquids If the liquid has to be mixed...
SL-MP-PP
For stirring of emulsions, dispersions, suspensions, etc. before starting the transfilling action. The mixing drum pump is fitted with mixing apertures. By moving a sliding sleeve with a lever, these holes can be opened or closed.
'Open' is for mixing inside the drum and 'Closed' is for pumping out of the drum.
All this can be achieved with one unit.
Recommendation: For good stirring of liquids of medium viscosity, use the powerful motor p400-A.
SL-PP-S
The feed screw (S) is dedicated for liquids of medium viscosity ( &Delta η > 200 mPas), if the impeller types A and R reach their limitations. Together with an induction motor, the SL-PP-S provides the ideal combination for gentle handling of liquid.
Recommendation: Induction motor with frequency inverter for variable flow rate.
Polypropylene Tube Drum Pump key features:
- Cleaning the pumping unit is greatly facilitated; the risk of fluid carry-over when moving the pump to a different container is minimized.
- No bearings in the wave channel.
- Motor power is transferred by proven, robust coupling (1) with curved teeth over the stainless steel coupling element (2) with a large double bearing.
- Of course, the sealless pump tubes are fully compatible with the sealed models, allowing you to use the pumping units with any motor from grün product range.
- Depending on the application you can select one of 3 different types of impellers: axial (A), radial (R) and feed screw (S).
