Metallurgy & Metal Processing Solutions

Rotho peristaltic pumps handle the demanding fluids of metal production - from abrasive mill scale slurries to corrosive pickling acids to precision plating chemicals.

Metallurgy Pumping Challenges

Metal processing environments combine extreme abrasion, aggressive chemistry, and high temperatures. Pumps face mill scale, metal fines, acid baths, and caustic solutions that destroy conventional equipment in weeks.

Extreme Abrasion: Mill scale, metal fines, and grinding swarf wear out impellers and seals
Aggressive Chemistry: Pickling acids (HCl, H2SO4), caustics, and plating solutions attack metals
High Temperatures: Coolants and process fluids often exceed 140°F (60°C)
Precise Metering: Plating and treatment processes require exact chemical dosing
Heavy Solids: Metal particles with high specific gravity settle quickly

Why Rotho for Metallurgy

Purpose-built features for metal processing applications

Handles Mill Scale & Fines

Reinforced hoses pass abrasive mill scale, grinding swarf, and metal fines that destroy centrifugal pumps. Six layers of nylon reinforcement provide extended service life.

Passes abrasive particles
6-layer reinforcement
No impeller wear
Single wear component

Chemical Resistant

Seven hose materials handle pickling acids, caustic soda, plating chemicals, and corrosive process fluids. Product only contacts the hose - no metal parts in the flow path.

Acid resistant options
Caustic compatible
No metal in flow path
Quick hose changes

Precision Chemical Dosing

Linear flow-speed relationship enables accurate metering for plating baths, treatment chemicals, and process additives. No slip means predictable output at any speed.

Accurate metering
No slip
Signal controlled
Batch repeatable

High Temperature Capable

Hypalon and EPDM hoses handle elevated temperatures common in metal processing. Suitable for hot coolant recirculation and warm process fluid transfer.
