A compact vertical single-screw (rotor-stator) volumetric pump engineered for vertical installation and continuous, low-pulsation transfer of viscous, shear-sensitive or solids-bearing fluids. The screw rotor and stator form a sealed cavity that translates rotation into positive displacement flow — producing stable flow rates, strong self-priming, low noise and high volumetric efficiency.
Key performance
- Flow rate: 1 to 200 m3/h
- Discharge pressure: 0 to 2.4 MPa
- Operating temperature: -20 °C to 120 °C (standard); optional designs to 150 °C
- Viscosity range: 10 to 1,000,000 cP (maximum viscosity capability up to 10^6 mm2/s)
- Maximum self-suction depth (typical): up to 7 m
Technical highlights
- Positive-displacement rotary screw design gives near-constant, low-pulsation flow — suitable for metering and dosing applications
- Handles a wide variety of media including low- to very-high viscosity fluids, slurries with suspended solids, and fiber-bearing or shear-sensitive products
- Gentle pumping action: minimal shear, no agitation or squeezing that would damage shear-sensitive materials
- Flexible installation: vertical base-mounted, wall-mounted, hoisted, barrel-mounted or submersible configurations; length can be adapted to pool/well depths
- Drive options: motor with gearbox, VFD for speed control, or mechanical speed regulation
- Construction materials: configurable metals and elastomers to match chemical compatibility, abrasive resistance and temperature requirements
- Easy maintenance: simple, compact design; routine service requires standard tools
Typical applications
Suitable for chemical processing, heavy oils, adhesives, paints and coatings, food-processing syrups, sewage/slurries and other industrial processes requiring controlled transfer of viscous or solids-containing fluids.
Options and customization
Available customization includes material selection (metals and stators), seals, connection flanges, drive and speed-control systems, and special high-temperature variants. Flow-rate or speed regulation and metering features can be supplied on request.
