Water and Wastewater Pump Solutions

The Rotho peristaltic pump is ideal for all those fluids that must not be contaminated, and must never come into contact with the mechanical parts of the pump because too chemically aggressive or dangerous.

The innovative technology that utilizes rotating rollers on bearings eliminates the need for refrigerating liquid inside the stator and ensure faster and more cost-effective maintenance.

Two are the main applications of the Rotho peristaltic pump in the water treatment industry:

  • chemicals metering
  • sludge transfer

Chemical feed and metering applications typically involve the use of sodium hypochlorite, sodium bisulphite, ferric chloride, lime, polyelectrolyte and other polymers. Especially sodium hypochlorite tends to off-gas during transfer causing vapour lock. The excellence performance of the Rotho peristaltic pump ensures that both the liquid and the air pockets that develop in the tubing are transferred with no clogging and without losing suction capacity, thereby maintaining the same efficiency of transfer as in the case of a smooth liquid.

The Rotho peristaltic pump can easily handle the transfer of sludge with suspended solid contents like gravels or metals, as there is no danger of blockage or clogging.

Benefits

  • Any contact between product and mechanical parts
  • Reverse flow by reversing motor
  • Can run dry without damage
  • Capable to transfer mixed phases without damages up to 45% of inner diameter
  • Capable to transfer sensitive products and pollutant products
  • Capable of pulling 98% of full vacuum
  • Valveless, sealless and glandless
  • Only tube to replace
  • Suitable for CIP application.

Filter Press Feeding

The Rotho peristaltic pump is the ideal solution for all pumping needs. It is simple to install, easy to use, and uncomplicated to maintain. It has no valves, seals or glands, no fluid contact with moving mechanical parts. Its low operating cost makes this pump a winner in many applications where abrasion resistance is the main requirement of the user, ensuring a longer pump life and the most cost-effective maintenance solution.

The application of the Rotho peristaltic pump to the high pressures feed of the "filter press" is very much recommended as it reduces the installed power by at least 50% when compared with other types of pumps. Filtration time is shorter because the flow rate is smoother, without any air pockets that may form when loading the filter chambers, and all the work is concentrated in a single pump, from filling to the final compaction of the pressed mud, which is an important aspect of the operating cost since pump regeneration is reduced to the simple replacement of the tubing.
