Industrial Applications
Rotho peristaltic pumps are built to handle the most challenging pumping applications across diverse industries.
Application Types
Discover how Rotho pumps solve complex pumping challenges
Chemical Dosing
Rotho pumps allow operators to maximize uptime by limiting chemical contact to a single chemically compatible hose element. Linear flow-speed relationship enables consistent and accurate metering with no slip.
- Accurate metering at any flow rate
- No slip across wide flow range
- Rapid hose replacement
- Signal controllable flow rates
Abrasive / Aggressive Slurries
Pumping abrasives will cause irreversible damage to traditional pump components. Rotho pumps' replaceable reinforced flow path is designed to handle abrasive and aggressive products with up to six layers of nylon reinforcement.
- Reinforced hose construction
- Industry-leading hose life
- Eliminates crystallization effects
- Single wear item design
Zero Shear / Shear Sensitive
The gentle rolling action of a Rotho pump provides zero-shear fluid transfer, making it ideal for shear-sensitive and foamy products. Free of glands, valves, and seals - no mechanical action touches the fluid.
- No shear - zero mechanical contact with fluid
- No product degradation
- Maintains foam stability
- Preserves particle integrity and solubility
Solids Handling / Viscous
Rotho pumps can transfer non-compressible solids up to 50% the inside diameter of the hose element. Completely self-priming, dry run capable, and can handle viscosities over 100,000cp.
- 50% solids handling capacity
- Self-priming operation
- Dry run capable
- Handles extreme viscosity
Aeration / Off-Gassing
The Rotho pumps isolated flow path is ideal for transferring products prone to off-gassing. Ideally suited for chemicals such as sodium hypochlorite or aqueous ammonia with a valve-free design that won't bind or airlock.
- Isolated flow path
- No air introduction
- Valve-free design
- Prevents airlocking
Chemical Compatibility
Fluid contacts only the internal hose - no mechanical seals, gears, or impellers to corrode. Choose from a wide range of hose materials to match your specific chemical requirements.
- EPDM, Silicone, Natural Rubber, Nitrile, Neoprene
- Handles acids, alkalis, and solvents
- No seal or gasket corrosion
- Simple hose swap for different chemicals
Sealless / Isolated Flow Path
Rotho pumps feature a completely sealless design where the pumped fluid is fully isolated within the hose. No mechanical seals, no packing glands, no contamination risk - ideal for hazardous, toxic, or high-purity fluids.
- Zero leak risk from seal failure
- Complete fluid containment
- No contamination of pumped product
- Ideal for hazardous and sterile applications
