Rotary Pump:The Industrial Core of Precision Delivery

In high-sanitary-standard fields such as food and pharmaceuticals,rotary pumps serve as critical equipment for fluid transfer due to their unique working principle.As a positive displacement pump,it employs a pair of precisely meshed rotors rotating synchronously in opposite directions.This creates a negative pressure zone at the inlet,drawing fluid into sealed chambers formed by the rotors and pump casing.As rotation continues,these chambers glide along the pump body wall from inlet to outlet,gradually compressing in volume to steadily discharge fluid,achieving continuous and pulse-free directional transfer.

Contamination-Free Design

All fluid-contact components are made of sanitary-grade stainless steel,with mechanical seals from non-toxic rubber,ensuring chemically uncontaminated delivery.Streamlined rotors and smooth pump cavities create a dead-zone-free structure,preventing media residue—especially critical for hygiene-sensitive substances like dairy products and medicinal liquids.

Stability

Its positive displacement characteristic ensures flow rate depends solely on rotational speed and chamber volume,with output stability virtually unaffected by back pressure fluctuations.This enables exceptional performance in transferring high-viscosity media like sauces and resins,while self-priming capability simplifies system design.

Critical Usage Guidelines

Strictly No Dry Running:Prime the pump with fluid before startup.Liquid film lubrication of mechanical seals(between rotating and stationary rings)prevents dry friction damage.

Media Purity:Extremely small clearances between rotors and pump cavities mean solid particles can scratch internal surfaces or jam rotors.Ensure fluids contain zero solid impurities.

Material Compatibility:Stainless steel rotors resist acidic/corrosive liquids poorly.Verify chemical compatibility between media and pump materials before selection.

Operational Monitoring:Regularly inspect mechanical seals for leaks and abnormal noises.Unusual sounds may indicate foreign object intrusion,requiring immediate shutdown and maintenance.

Reliable operation hinges on deep understanding of its working principle:advantages lie in precision chamber-volume variation and material safety,while limitations stem from mechanical seal lubrication needs,micro-clearance structures,and material chemical tolerance boundaries.Correct selection and standardized operation unlock its irreplaceable value in sanitary fluid transfer.
