A heavy-duty twin-screw transfer pump designed for reliable, continuous handling of a wide range of liquid media — from light hydrocarbons to high-viscosity and abrasive fluids. The pump is a rotary upright design with gears and bearings located externally so moving parts are not immersed in the conveyed liquid, reducing contamination and easing maintenance.
Key performance characteristics:
- Viscosity capability: 1–1,500 mm2/s
- Maximum discharge pressure: up to 4.0 MPa
- Flow capacity: 1–2,000 m3/h
- Operating temperature range: -15°C to 280°C
What it handles:
- Low-viscosity fluids: gasoline, naphtha, light fuel oils, liquefied petroleum gas fractions
- Medium- and high-viscosity fluids: lubricating oil, hydraulic oil, cutting and cooling oils, waxes, tar, asphalt, molasses
- Corrosive or contaminated liquids: acids, alkalis, slurries with entrained solids
- Multiphase and gas-containing media: crude oil with free gas, oily water mixtures
Industrial applications:
- Oil & gas: crude oil transfer, multiphase pipeline service, loading/unloading on tankers, deck and cargo pumping
- Maritime: tanker fuel and lubricant supply, main-engine lubrication, bunker operations
- Petrochemical and refinery: transfer of naphtha, light hydrocarbons, chemical feedstocks and intermediate products
- Power and heavy industry: thermal power plant feed, fuel oil handling, heavy fuel injection
- Chemical processing: polymers, coatings, liquid sulfur, slurries and corrosive liquids
Advantages for B2B operations:
- Wide operating envelope across viscosity, temperature and pressure reduces need for multiple pump types
- External gearing and bearings simplify service and reduce risk of product contamination
- Robust design supports dry running and pump-out of gas-containing and multiphase fluids
- Compact footprint and screw-profile design suited to long-distance pipeline transfer and marine installations
Typical supply scope can include different shaft seals, connection flanges, and materials selected for compatibility with the specific media and operating conditions. For selection, provide required flow, discharge pressure, fluid properties (viscosity, temperature, density, solids content), and application environment.
