Stainless Steel double rotary food triple Screw vacuum pump
 
TheStainless Steel double rotary food triple Screw vacuum pumpis a positive displacement pump madeof 304/316Lstainless steel with hygienic quick-clamp connections. It relies on the rotation of ascrew rotor inside a stator or pump chamber to convey media. It offers pulsation-free, low-shearhandling of high-viscosity media, soft particles, or shear-sensitive products. The food screw pump is typicallyinstalled in clean fluid conveying pipelines in the food, pharmaceutical, daily chemical, andbioengineering industries, used for conveying, batching, and filling thick pastes, sauces,pharmaceutical liquids, creams, fermentation broths, and similar media.
Based on the screw configuration and pump chamber design, two main types are available:
G-type progressive cavity pump (single screw):Uses an eccentric single rotor and an elasticstator. Simple construction, good self-priming capability, suitable for medium-to-high viscosityand particle-containing media. High cost-effectiveness
Transparent-window twin-screw pump:Uses a twin-screw meshing structure with a transparentpump chamber that allows real-time observation of media flow and screw operation. Suitable forclean applications where process monitoring is critical.
Both types can be configured with different flow/pressure ratings, stator/chamber materials, sealtypes, and motor options (variable frequency / explosion-proof). Versions include basic conveyingvariable speed, explosion-proof, and high-viscosity special types to meet various applicationrequirements.

Comparison with ordinary screw pumps:

  • Ordinary screw pumps are often made of cast iron or non‑hygienic stainless steel, with threaded or flanged connections that have cleaning dead legs, making them unsuitable for high‑cleanliness applications like food and pharmaceuticals. Our series uses 304/316L hygienic stainless steel and quick‑clamp connections for dead‑leg‑free cleaning and rapid disassembly, perfectly adapted to clean applications.

  • Our triple screw pump further improve conveying stability and wear life through precision‑machined rotors and high‑elasticity food‑grade stators / high‑precision twin screws. Optimized mechanical seals and polished flow paths reduce product residue and leakage risk. Customizable port sizes, motor configurations, and hygienic accessories are available. Overall cleanliness, durability, and application adaptability are superior to similar products on the market.

Progressive cavity pump (single screw) vs. twin‑screw pump:

  • The single‑screw pump is simpler, lower cost, has good self‑priming, and suits soft particles, high viscosity, and medium‑low pressure. It has slightly more pulsation than the twin‑screw.

  • The twin‑screw pump delivers even smoother, nearly pulsation‑free flow with even lower shear. The transparent window allows real‑time monitoring. It is ideal for applications demanding extremely smooth conveying and process visibility, though at a higher cost.

G‑type progressive cavity pump (single screw): Composed of a stainless steel pump body, eccentric rotor, rubber stator, hygienic quick‑clamp connections, mechanical seal, motor, and stainless steel base. It connects quickly and dead‑leg‑free to hygienic pipelines, tanks, and equipment via clamp fittings and food‑grade seals. During operation, the motor drives the rotor to rotate eccentrically inside the stator, forming continuous sealed cavities that move media from inlet to outlet, achieving smooth, pulsation‑free conveying.

Transparent‑window twin‑screw pump: Composed of a stainless steel pump body, transparent pump chamber, twin screw rotors, hygienic quick‑clamp connections, mechanical seal, motor, and frame. The motor drives the twin screws to rotate in mesh, creating continuous volumetric chambers that draw in and push out media. The conveying is pulsation‑free with extremely low shear. The transparent window allows direct observation of media flow and screw operation, facilitating troubleshooting and process monitoring

Digital advantages

  • Intelligent monitoring and remote visibility: Built‑in high‑precision sensors collect key data such as flow, pressure, temperature, and vibration. The twin‑screw pump can also use its transparent window plus external sensor modules for real‑time feedback. Data is remotely visible on mobile phones/computers, making equipment status transparent and eliminating traditional manual inspection.
  • Energy saving and soft start: Equipped with a variable frequency control system, speed adjustable from 10% to 100% – on‑demand feeding. Saves >20% energy compared to fixed‑speed pumps. Soft start reduces mechanical shock.
  • Multiple protections and early warning:Integrated dry‑run, over‑pressure, over‑temperature, and overload protection. Automatic alarm/shutdown on abnormality. Early warning accuracy ≥95%. Predicts stator wear (single screw) or screw/bearing aging (twin screw), avoiding sudden production stoppage.
  • Data traceability and compliance: Operating data is automatically stored and traceable, supporting GMP/FDA audits. Generates records of CIP/SIP cleaning, temperature, and pressure curves. Meets digital compliance requirements of food and pharmaceutical hygienic grades. The twin‑screw pump also enables full electronic traceability (material batch, processing lot, test reports, QR code traceability).
  • Industrial interconnection and smart maintenance:Supports PLC/DCS communication protocols for integration into factory automation systems. Remote start/stop, speed adjustment, and diagnostics reduce on‑site labor. Adapts to Industry 4.0 and smart workshop management. The twin‑screw pump can automatically record running hours and maintenance points, predict component wear, and assist in planning maintenance and spare parts.
