Peristaltic pump for dosing chemicals and transferring sludges
In the water treatment sector, the main applications for Rotho peristaltic pumps involve dosing chemicals and transferring sludges.
Dosing chemicals
The chemicals involved are mainly sodium hypochlorite, sodium bisulphite, ferric chloride, polyelectrolyte and other polymers.
When dosing difficult products such as sodium hypochlorite which forms a gas during transfer, the Rotho peristaltic pump maintains the same efficiency as it transfers both the liquid and the cushion of air it produces without blocking the line and without reducing pumping capacity.
Transferring sludges
The Rotho peristaltic pump is ideal for pumping sludges and fluids containing suspended solid parts such as stones or pieces of metal, as there is no risk of blockage or clogging.
Advantages of the Rotho pump for water treatment
- Ease of operation
With the Rotho pump there is no risk of blocking or clogging, it resists wear from abrasion better than other pumps and consumption of the tube due to abrasion is reduced. - No valves or seals
- No contact between the fluid and moving mechanical parts
- Can operate dry
- Long term resistance
The Rotho peristaltic pump is forst choice in numerous applications where the user's priority is resistance to abrasion and extended working life. - Feeding press filters
Use of the Rotho peristaltic pump to feed press filters at high pressures reduces installed power by 50% with respect to other types of pump. - Short filtering times
It reduces filtering times as pumping has a more regular flow and there are no air pockets when the chambers formed by the filter plates are filled. All the work is concentrated in a single pump, from filling to final compacting of the pressed slurry. - Low running costs
Pump regeneration is limited to replacement of the tube.
