The Wall-Mounted Vertical Screw Pump is a highly efficient and space-saving positive displacement pump designed for transferring viscous, shear-sensitive, or particulate-laden fluids in industrial and commercial environments. This innovative design mounts vertically on walls or frameworks, making it ideal for facilities where floor space is limited or hygiene standards are high, such as food processing, chemical production, pharmaceuticals, wastewater treatment, and cosmetics manufacturing.
Unlike traditional horizontal screw pumps, the vertical wall-mounted design integrates a compact motor, stator, and rotor assembly in a vertically aligned body, ensuring continuous flow and stable pressure with minimal vibration. The pump’s body and wetted components are typically constructed from high-grade stainless steel (304 or 316L), ensuring superior corrosion resistance and long-term durability, even when handling chemically aggressive or high-viscosity materials.
This screw pump operates on the progressive cavity principle, where the helical rotor rotates within a precisely engineered elastomer stator, forming continuously sealed cavities that move fluid smoothly from the suction end to the discharge outlet. This design ensures gentle handling of sensitive materials, prevents product degradation, and maintains a steady, pulsation-free flow, making it ideal for metering, dosing, and continuous feed operations.
The Wall-Mounted Vertical Screw Pump can handle a wide range of viscosities—from thin fluids like water to thick pastes, slurries, and suspensions—without losing efficiency. It is widely used for transfer, feeding, dosing, and circulation applications in hygienic and industrial sectors.

Space-Saving Vertical Structure
The wall-mounted vertical design saves valuable floor space, facilitating easy cleaning and maintenance in compact facilities.
Smooth and Stable Flow
Progressive cavity pumping ensures uniform discharge with minimal pulsation or shear stress on materials.
Wide Viscosity Range
Handles fluids from low-viscosity liquids to high-viscosity slurries, gels, and semi-solids efficiently.
Material Options for Versatility
Available in stainless steel 304/316L, carbon steel, or special alloys depending on media compatibility and application requirements.
Simple Maintenance and Easy Installation
Modular components, detachable stator and rotor, and top-down design allow for convenient servicing without disassembly of the entire unit.
Corrosion and Wear Resistance
Precision-machined rotors, high-grade elastomer stators (NBR, EPDM, FKM), and optional surface treatments enhance durability.
Energy-Efficient Design
Low power consumption with high volumetric efficiency and low operating noise.
Customizable Flow and Pressure
Configurable flow rates, pressure levels, and mounting brackets to suit specific site conditions.

The Wall-Mounted Vertical Screw Pump is widely applied in industries where space optimization, hygiene, and flow precision are essential. Below are major use cases:
Used for transferring viscous food products such as honey, syrup, jam, yogurt, chocolate, tomato paste, sauces, and fruit concentrates. The gentle pumping action maintains the texture and flavor integrity of sensitive food products.
Ideal for conveying pharmaceutical creams, gels, ointments, and active ingredient slurries. The sanitary design (316L stainless steel and FDA-grade elastomers) ensures contamination-free transfer and compliance with GMP standards.
Used in producing and transferring shampoos, lotions, creams, and gels. The low-shear operation prevents product aeration and maintains consistent viscosity during transfer.
Efficiently handles aggressive or viscous fluids like resins, adhesives, polymers, detergents, lubricants, and emulsions. The pump can be customized for corrosive chemical compatibility.
Used for dosing and transferring sludge, activated carbon suspensions, and other thick wastewater treatment materials. Its robust stator-rotor design ensures clog-free and stable operation.
Handles glue, dye, ink, latex, and coating materials with precision metering and consistent flow control.
Ensure a solid wall mount with load-bearing capability.
Use vibration-damping brackets to reduce noise and mechanical stress.
The pump should be installed vertically with proper alignment between the motor and rotor axis.
Provide sufficient clearance for maintenance and stator replacement.
Connect inlet and outlet piping using flexible joints to minimize vibration transmission.
Verify all electrical and mechanical connections.
Check lubricant levels and seal conditions.
Prime the pump with the medium to prevent dry running.
Start the motor at low speed to confirm rotation direction.
Gradually increase to operational speed.
Monitor for leaks, vibration, or abnormal sound.
Avoid running the pump dry; it can damage the stator.
Ensure consistent feed to prevent cavitation.
For viscous materials, use preheating or pre-mixing if required.
Clean the pump regularly to maintain hygiene and prevent buildup.
Regularly inspect the stator and rotor for wear or deformation.
Replace seals promptly when leakage is detected.
Lubricate bearings and drive components periodically.
Store spare parts in a dry, clean environment.
| Problem | Possible Cause | Solution |
Pump not starting | Power failure or incorrect wiring | Check power supply and connections |
Low flow rate | Worn rotor/stator or air leakage | Replace worn parts and check seals |
Excessive noise | Dry running or misalignment | Stop pump immediately, realign and re-prime |
Leakage from shaft seal | Worn mechanical seal | Replace or adjust seal |
Overheating | High viscosity or blocked suction | Check for blockages and reduce viscosity |
Irregular discharge | Air pockets or cavitation | Ensure proper suction and vent trapped air |
