Water & Wastewater Treatment Solutions

Rotho peristaltic pumps reliably handle the toughest water treatment applications - from abrasive sludge transfer to precise chemical dosing - with minimal maintenance and maximum uptime.

Water Treatment Challenges

Water and wastewater treatment facilities face demanding pumping requirements around the clock. Thick sludge with grit and debris, corrosive treatment chemicals, and the need for precise dosing all take their toll on conventional pumps - leading to frequent failures and service disruptions.

Sludge & Grit: Thick sludge containing sand, gravel, and debris destroys impellers and seals
Chemical Dosing: Lime slurry, polymers, and disinfectants require accurate, reliable metering
Variable Conditions: Flow rates and solids content change constantly
24/7 Operations: Treatment plants run continuously - reliability is critical
Regulatory Compliance: Accurate dosing is required to meet discharge permits

Why Rotho for Water Treatment

Purpose-built features that solve water industry challenges

Handles Solids-Laden Sludge

Transfer thick sludge containing grit, rags, and debris without clogging. Rotho pumps pass non-compressible solids up to 50% of the hose inner diameter - eliminating blockages that plague other pumps.

50% solids handling
No clogging issues
Handles rags & debris
Self-clearing design

Accurate Chemical Dosing

Precise metering of lime slurry, polymers, chlorine, and other treatment chemicals. Linear flow-speed relationship ensures consistent dosing rates. Suitable for drinking water system components.

Zero slip accuracy
VFD compatible

Self-Priming Operation

Completely self-priming with suction lifts up to 29.5 feet. Ideal for dewatering, sump pumping, and applications where pump placement is above the fluid level.

29.5 ft suction lift
Dry-run capable
No priming required
Reversible flow

Low Maintenance

Single wear part design means the only maintenance is periodic hose replacement. No seals, impellers, or check valves to fail - maximizing uptime and reducing labor costs.
