Transferring slurries and dosing chemical additives for concrete are both important activities for the building industry.
The Rotho peristaltic pump is ideal for pumping abrasive slurries or slurry containing suspended solid parts such as stones or metal objects without blocking or clogging as there are no valves or seals.
Its ability to pump from a depth of -8.5 m solves material transfer problems impossible for other types of pump.
The Rotho pump can operate dry without burning out or damaging the tube.
The retractable roller device rapidly frees the tube from the grip of one of the two rollers, allowing "flushing" to be performed whenever necessary. It avoids the tube being stressed by the compressing action of the rollers, particularly in the presence of aggressive and/or high-temperature washing fluids.
The retractable roller device can be operated in perfect safety by an external lever.
The retractable roller device is recommended for all processes involving the pumping of fluids with a tendency to settle and create blockages after a period of inactivity to keep the tube clean and avoid unexpected and damaging clogging. It can be installed on all Rotho pumps in the MS series and the PSF1 model.
