Product Description
The Sanitary Twin Screw Pump is a high-performance hygienic positive displacement pump featuring two intermeshing screws that deliver pulsation-free, gentle product transfer. Its unique design allows it to function as both a process pump and a CIP (Clean-in-Place) pump, eliminating the need for separate CIP pumps in hygienic processing systems.
Constructed in AISI SS316L (1.4404) stainless steel with precision-machined screws and hygienic double mechanical seals, this pump meets the highest standards of food and pharmaceutical hygiene. The wide speed range (10-3,500 rpm) enables it to handle both low-flow, high-viscosity product transfer and high-flow CIP cleaning with a single pump.
Applications
- Food & Beverage: sauces, pastes, fruit preparations, syrups, chocolate, confectionery
- Dairy: milk, cream, yogurt, cheese, ice cream mix, infant formula
- Pharmaceutical: active ingredients, proteins, immunoglobulins, blood products, suspensions
- Cosmetics: creams, lotions, emulsions, shampoos
- Brewery: beer, wort, yeast, hop extracts
- CIP Systems: serves as both process pump and CIP return/supply pump
Quality Assurance
All Sanitary Twin Screw Pumps are manufactured under ISO 9001 quality management system with full material traceability. Each pump undergoes hydrostatic pressure testing, performance verification, surface finish inspection (Ra ≤ 0.5 μm), and material certification (EN 10204 3.1). Comprehensive documentation including test protocols, GA drawings, and maintenance manuals is provided with every shipment.
Why Choose Our Positive Displacement Pumps
Dual Function: Process + CIP Pump
Wide speed range (10-3,500 rpm) allows one pump to handle both product transfer and CIP cleaning, reducing equipment count and system complexity.
Ultra-Gentle Product Handling
Two intermeshing screws deliver pulsation-free flow with minimal shear, protecting delicate products like yogurt, proteins, and pharmaceutical suspensions.
Premium Hygienic Design
AISI SS316L (1.4404) construction with Ra ≤ 0.5 μm surface finish, double mechanical seals, and 3-A/FDA/EHEDG compliance for maximum product safety.
Wide Viscosity & Temperature Range
Handles 0.5 to 1,000,000 cP and -40°C to 150°C, from thin CIP solutions to thick pastes and hot sterilization processes.
