The G-Type Sanitary Screw Pump is widely used in industries that demand hygienic fluid handling, precision dosing, and consistent output:
Chocolate, syrup, honey, cream, and sauces: Gentle pumping ensures product integrity.
Dairy products: Maintains texture while transferring milk, yogurt, and other dairy liquids.
Juices and liquid concentrates: Minimizes shear and prevents foaming.
Vaccines, injectable solutions, and biofluids: Maintains sterility and prevents contamination.
Cosmetic creams and lotions: Smooth transfer of high-viscosity formulations.
Acids, alkalis, and corrosive chemicals: 316L stainless steel construction ensures durability.
Viscous resins and polymers: Provides consistent flow without clogging.
Laboratory or pilot plant use: Precise dosing and transfer of small volumes.
Cosmetic production lines: Hygienic handling of gels, oils, and emulsions.
To ensure optimal performance and longevity, follow these operational guidelines:
Mounting: Install horizontally or vertically, depending on line layout. Ensure alignment of inlet and outlet.
Connection: Use sanitary tri-clamps or flange connections. Tighten securely to avoid leaks.
Drive Alignment: Connect the pump to the motor or drive system using flexible couplings if needed.
Priming: For viscous liquids, pre-fill the pump cavity or allow gradual start-up to avoid dry running.
Start-Up: Run the pump at low speed initially to prime and avoid sudden pressure surges.
Flow Adjustment: Adjust speed via variable frequency drive (VFD) or motor control to achieve desired flow.
Monitoring: Check for unusual vibrations, temperature rises, or abnormal noise.
Cleaning: Perform regular CIP/SIP cleaning for sanitary compliance. Flush the pump with compatible cleaning solutions after each batch.
Routine Inspection: Check seals, bearings, and rotor for wear.
Lubrication: Ensure proper lubrication of drive components.
Replacement Parts: Use OEM-certified rotors, stators, and seals for consistent performance.
The pump can handle viscous liquids, shear-sensitive fluids, food pastes, pharmaceuticals, and chemical solutions. Maximum viscosity up to 100,000 cP.
Yes, it can handle liquids up to 120°C, and options for higher temperatures are available with upgraded materials or cooling jackets.
It is suitable for mildly abrasive fluids, but for highly abrasive materials, consider abrasion-resistant coatings or heavy-duty rotors.
