Sanitary Twin-Screw Pump

The SLGP Series Sanitary Twin-Screw Pump is a highly efficient, volumetric displacement pump designed to deliver maximum cost-effectiveness and production efficiency. Featuring a non-contacting, axial-flow design, the SLGP series delivers ultra-gentle, low-pulsation product transfer while fully supporting high-speed CIP/SIP processes within a single unit. With an extremely versatile performance envelope and an optional heating/cooling jacket, a single pump can handle diverse material viscosities, temperatures, and pressures, eliminating the need for separate process and cleaning pumps.

Key Technical Advantages & Features

• Two-in-One Functionality (Process & CIP/SIP): With a wide speed range spanning from 100 to 3,600 RPM, this pump acts as a process pump at lower speeds and a high-flow CIP/SIP return pump at maximum speeds. This setup eliminates the need for additional CIP pumps, piping, or valves, reducing footprints and capital investment.
• Optional Heating/Cooling Jacket: Designed for temperature-sensitive or high-viscosity fluids that solidify or stiffen when cooled (e.g., chocolate, syrup, honey, fats). By circulating hot water or steam through the outer jacket, it maintains the ideal product temperature, lowers fluid viscosity, and ensures a smooth, continuous flow without clogging or damaging the motor during start-up.
• Ultra-Gentle, Low-Pulsation Delivery: Unlike the high-impact forces of centrifugal pumps, the squeezing action of rotary lobe pumps, or the reciprocating pulses of piston pumps, the SLGP moves materials axially through sealed chambers. This design preserves the integrity, shape, size, and surface finish of sensitive media.
• Non-Contact & Friction-Free Design: The dual interlocking screws rotate smoothly within the pump casing without any metal-to-metal contact. This ensures zero operational wear and allows the pump to effortlessly handle non-lubricating, corrosive, or abrasive fluids.
• Bi-Directional Flow Flexibility: The symmetrical internal design allows for full bi-directional operation. You can reverse the pump's flow (switching the inlet and outlet) by simply changing the shaft's rotation direction, requiring no mechanical modifications.
• Superior Self-Priming & Vacuum Capability: The SLGP series delivers strong, reliable self-priming capabilities, drawing a vacuum down to -0.8 bar when the pump chamber is primed.
• Optimized High-Pressure Shaft Seal: The specialized feed configuration maintains ambient, stable pressure at the shaft seal, ensuring excellent sealing performance and preventing leaks even during high-pressure discharge operations.

Flexible Configurations & Sizing

Our integrated modular system offers multiple pump housings and a broad selection of screw profiles to match your specific requirements:

• Flow Rate Range: From a precise 40 L/h to a high-capacity 150 t/h.
• Viscosity Range: Effortlessly processes fluids from 1 to 500,000 cSt.
• Solid Handling: Accommodates large, soft, or delicate particles up to 40 mm in diameter without damaging them.
• Body Type Options: Choose between the Standard Type for ambient liquids or the Jacketed Type for temperature-controlled media.

Note: Different screw pitches allow the pump to achieve distinct flow rates even under identical viscosities, pressures, and motor speeds, allowing for exact process tuning.

Compliance & Hygienic Standards

Built for zero-contamination environments, the SLGP series features a dead-leg free internal geometry that ensures total drainability and effortless cleaning. It fully complies with the world's strictest sanitary guidelines:

• GMP Certified Design
• 3A Sanitary Standards
• FDA Approved Material Construction
