Rotho peristaltic pumps are ideal for the metalworking sector as they have no valves or seals and there is no contact between the product and mechanical parts.
These characteristics make the pump more resistant to abrasion from metal swarf and corrosive pastes. Wear caused by abrasion is limited to the tube only. For the same reason, there is no risk of blockages or clogging.
The retractable roller device rapidly frees the tube from the grip of one of the two rollers, allowing it to be "flushed" whenever necessary.
This 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 system enables the tube to be kept clean and avoids unexpected and damaging clogging. It can be installed on all Rotho pumps in the MS series and on the PSF1 model incorporated in a work process involving the pumping of fluids which tend to settle and create blockages after a period of inactivity.
