The Ceiling-Mounted Vertical Screw Pump is an innovative and space-saving Progressive cavity pump designed for transferring highly viscous, abrasive, or shear-sensitive materials in industrial and sanitary environments. Unlike conventional floor-mounted pumps, this unique design allows installation directly onto the ceiling or elevated framework, freeing up valuable floor space and ensuring a clean, clutter-free production environment.
By combining a vertical orientation with a ceiling suspension system, the pump can deliver fluids directly downward into tanks, containers, or production lines, making it ideal for continuous feeding, dosing, and transfer applications in confined or hygiene-critical facilities.
The pump operates based on the progressive cavity principle — a helical rotor rotating inside a precision-engineered elastomer stator. This configuration forms sealed cavities that progress continuously, pushing the medium smoothly from inlet to outlet. This mechanism ensures a steady, low-pulsation flow, preserving product structure and consistency, even when handling viscous or particulate materials.
Constructed from high-quality stainless steel (304 or 316L), the ceiling-mounted vertical screw pump offers exceptional resistance to corrosion and chemical attack. It is especially suitable for food, pharmaceutical, cosmetic, and chemical processing industries, where hygiene, reliability, and ease of maintenance are critical.
The pump’s modular design allows easy assembly, cleaning, and maintenance from below the installation point, with detachable stator and rotor components accessible without removing the entire unit. For sanitary applications, CIP (Clean-in-Place) and SIP (Sterilization-in-Place) options can be integrated.

The Ceiling-Mounted Vertical Screw Pump offers unique installation flexibility, making it suitable for industries that demand efficient, hygienic, and space-optimized fluid transfer. Below are the major application areas:
Perfect for transferring viscous materials such as:
Syrups, honey, chocolate, molasses, or caramel
Fruit puree, jam, or concentrated juices
Yogurt, sauces, cream, or paste-based products
The gentle, non-shearing pumping action prevents air entrainment and preserves texture and flavor integrity. The ceiling mount also simplifies cleaning processes and ensures contamination-free operation.
Used for transferring:
Ointments, gels, serums, and creams
Culture media, suspensions, or chemical reagents
The sanitary design with FDA-compliant elastomers ensures total hygiene and compliance with GMP and pharmaceutical-grade production standards.
Handles high-viscosity fluids such as:
Shampoos, lotions, gels, or facial creams
Emulsions and surfactant mixtures
The ceiling-mounted structure keeps floor space open, improving operational efficiency and minimizing contamination risks.
Transfers aggressive or viscous substances including:
Resins, adhesives, lubricants, paints, or detergents
Polymer emulsions and slurry compounds
The robust rotor-stator assembly provides resistance to corrosion and abrasion, maintaining stable performance under harsh conditions.
Used for dosing and transferring:
Sludge, chemical flocculants, and lime suspensions
Thickened slurry and semi-solid waste streams
The vertical downward flow minimizes clogging and simplifies integration into overhead sludge-handling systems.
Utilized in:
Paper production, textile dyeing, and coating lines
Glue and ink transfer systems
Automatic metering and filling systems
Ensure a robust ceiling structure capable of bearing the pump’s weight.
Use anti-vibration suspension brackets to minimize mechanical stress.
Align the motor and pump vertically to prevent shaft bending.
Connect flexible hoses or joints to absorb vibration and allow maintenance access.
