Vs Vertical Mount Single Screw Pump

Vertical single-screw volumetric (rotor) pump engineered for vertical installation and continuous, low-pulsation transfer of viscous, shear-sensitive and particulate-bearing liquids. The pump uses a single rotating screw (rotor) working against a flexible stator (bush) to form sealed cavities that convey fluid with a smooth, proportional flow.

Key features

• Positive displacement, single-screw design for stable flow and minimal pressure fluctuation
• Gentle handling: no squeezing, low shear — suitable for shear-sensitive products
• Wide viscosity capability: suitable for low- to very-high viscosity media (see performance range)
• Can convey fluids containing solids, fibers or suspended particles
• Strong self-priming capability (typical maximum suction lift up to 7 m under normal conditions)
• Very low vibration and noise; continuous, uninterrupted transport
• Nearly pulse-free flow; can be used for metering applications when equipped with speed control
• Flow is proportional to speed — simple and effective capacity control with VFD or mechanical drives
• Simple construction for easy on-site maintenance (general toolbox typically sufficient)
• Construction materials selectable (different metals and elastomers) to suit chemical compatibility and abrasion resistance

Typical installation & drive options

• Vertical installation: base-mounted, wall-mounted, hoisting-mounted or barrel-mounted configurations
• Can also be supplied as horizontal or submersible variants depending on application
• Drive options: direct motor + gearbox, VFD (variable frequency drive) speed-regulation, or mechanical speed-regulation
• Suitable for installations in pits, wells, tanks, culverts and barrels; installation length can be customized to site conditions

Performance range

• Flow rate: 1 to 200 m3/h
• Discharge pressure: 0 to 2.4 MPa
• Medium temperature: -20 °C to 120 °C (special designs available up to 150 °C)
• Medium viscosity: approximately 10 to 1,000,000 cP (high-viscosity specialty designs available)

Applications

• Transfer and dosing of adhesives, resins, heavy oils, sludges and pastes
• Food, chemical and cosmetic processes where gentle handling is required
• Wastewater, slurry and solids-laden fluid handling
• Metering applications where steady, proportional flow is needed

Customization and procurement notes

• Material selection (metallic wet-end and elastomer stators) should be specified based on fluid chemistry and abrasive content
• Provide required flow, discharge pressure, operating temperature and viscosity at quotation stage to ensure correct rotor/stator materials and drive sizing
• Optional features: flow control via VFD, hygienic/end-point flanges, hard-facing or abrasion-resistant components for high-wear services

This vertical single-screw pump is suitable for industrial and processing applications that require reliable, low-pulsation transfer of viscous or particulate-laden liquids with simple maintenance and flexible installation options.
