Twin Screw Pumps

TSB supplies Twin Screw Pumps in Jordan for demanding oil and gas, refinery, petrochemical, chemical, terminal and industrial process applications. Twin screw pumps are positive-displacement pumps designed for reliable transfer of low- to high-viscosity liquids, including hydrocarbons, fuel oils, polymers, bitumen and selected multiphase or solids-containing fluids.

Available with magnet drive or mechanical shaft sealing, the pump can be configured according to process containment, maintenance philosophy, fluid characteristics and project requirements. Single-volute and double-volute configurations provide flexible solutions for process units, tank farms and demanding transfer applications.

Typical Technical Configuration

Specifications and available options may vary. Contact TSB for full details and configuration support.

Twin Screw Pumps with Magnet Drive

Magnetic-drive twin screw pumps provide a sealless positive-displacement pumping solution for applications where process containment is particularly important.

Torque is transmitted through a permanent magnetic coupling while a stationary containment shell separates the process liquid from the atmosphere. This eliminates the conventional dynamic shaft seal and helps reduce potential leakage points associated with mechanical sealing systems.

The configuration is particularly suited to:

• Aggressive liquids
• Toxic liquids
• Explosive process fluids
• Hydrocarbons
• High-value products
• High-viscosity liquids
• Solids-containing fluids
• Applications with stringent environmental or containment requirements

Additional configurations can include heated pump sections, thermal barriers, internal filtration, external flushing arrangements and secondary containment concepts.

Single Volute – API – Magnet Drive

Single-volute magnetic-drive twin screw pumps provide an API 676 process-pumping configuration combined with sealless magnetic-drive technology.

The modular axial-split construction is suitable for process and tank-farm applications and can be configured with different materials, heating arrangements and operating options according to the pumped medium.

Key design options can include:

• API 676 pump configuration
• Permanent magnetic coupling
• API-oriented magnetic-drive configuration
• Axially split modular casing
• Centerline mounting
• Cartridge-style construction
• Integrated pressure-limiting arrangements
• High-viscosity optimized designs
• Heated or cooled pump configurations
• Internal filtration for selected solids-containing liquids
• Secondary containment arrangements
• Different containment-shell materials

This configuration is particularly suitable where the advantages of twin screw hydraulics and sealless process containment are required in the same pumping system.

Twin Screw Pumps with Mechanical Seal

Mechanical-seal twin screw pumps provide a conventional shaft-sealed solution with broad flexibility for refinery, petrochemical, oil and gas, terminal and industrial process applications.

The sealing system can be selected according to process pressure, temperature, fluid properties and plant requirements. Mechanical seals, cartridge arrangements and gland-packing configurations are available depending on the selected pump design.

Mechanical-seal configurations can provide:

• API 676 pump designs
• API 682 / ISO 21049 mechanical seal configurations
• Single- and double-volute arrangements
• Process and tank-farm designs
• Multiple seal and flushing arrangements
• Heating and cooling options
• High-viscosity capability
• Application-specific materials
• Heavy-duty bearing arrangements
• Maintainable modular construction

Single Volute – API – Mechanical Seal

Single-volute twin screw pumps with mechanical sealing provide a flexible API 676 solution for process and tank-farm duties.

The axial split modular casing provides convenient access to internal components, while different shaft sealing arrangements allow the pump to be adapted to the operating conditions.

Available configurations can include:

• API 676 construction
• Mechanical seals according to applicable process requirements
• API 682 / ISO 21049 seal configurations
• Cartridge seal arrangements
• Gland packing
• Centerline mounting
• Oil-lubricated or grease-lubricated bearings
• Heated or cooled pump arrangements
• Application-specific metallurgy
• High-viscosity designs

Typical services include hydrocarbons, fuel oils, polymers, bitumen, tar, aggressive chemicals and selected solids-containing liquids.

Double Volute – API – Mechanical Seal

Double-volute twin screw pumps provide a heavy-duty solution for high-capacity, high-pressure, viscous and multiphase process applications.

The double-volute configuration uses specialized twin screw hydraulics designed for smooth, low-pulsation transfer while handling difficult process fluids.

Available features can include:

• API 676 configuration
• Double-volute hydraulic design
• Low-pulsation operation
• Low-NPSH design
• Variable rotor configurations
• Cartridge-style construction
• Contact-free rotor clearances across the permissible operating range
• Double-acting seal configurations
• Multiple mechanical seal and flushing arrangements
• Heated pump configurations
• Thermal barriers for hot liquids
• Special construction materials

The design is particularly suitable for applications involving crude oil, fuel oil, bitumen, asphalt, tar, resins, residues and multiphase mixtures containing liquid, gas and solids.

Magnet Drive vs Mechanical Seal

The appropriate configuration depends on the process medium, leakage requirements, operating conditions, maintenance strategy and project specification.

Handling High-Viscosity Fluids

Twin Screw Pumps are particularly effective for liquids whose viscosity makes conventional centrifugal pumping difficult.

The positive-displacement principle transfers a defined volume of liquid with each rotation, allowing stable pumping across a broad range of viscosities.

Typical high-viscosity applications include:

• Heavy fuel oil
• Crude oil
• Bitumen
• Asphalt
• Tar
• Polymers
• Resins
• Lubricating oils
• Heavy hydrocarbons
• Process residues

Heating jackets and thermal arrangements can also be incorporated where the product must be maintained at temperature to control viscosity.

Multiphase & Solids-Containing Applications

Selected Twin Screw Pump configurations can handle process streams containing combinations of liquid, gas and solids.

Special rotor geometry, clearances, materials and sealing arrangements can be selected according to the expected process conditions.

Applications can include:

• Multiphase oil and gas streams
• Liquids containing suspended solids
• Process residues
• Polymers
• High-viscosity products with entrained gas
• Hydrocarbon mixtures
• Industrial process slurries within suitable operating conditions

The exact hydraulic and mechanical configuration should be selected according to the fluid composition and expected operating envelope.

Materials & Configuration

Twin Screw Pumps can be supplied in different materials according to corrosion, erosion, temperature, viscosity and solids content.

Available construction materials can include:

• Carbon steel
• Stainless steel
• Duplex stainless steel
• Super Duplex stainless steel
• Hardened rotor materials
• Wear-resistant coatings
• Nickel alloys
• Titanium
• Other application-specific special alloys

Magnetic-drive configurations also provide different containment-shell materials, while mechanically sealed versions can be configured with sealing materials and flushing plans appropriate for the process.

Applications

• Oil and gas facilities
• Refineries
• Petrochemical plants
• Tank farms
• Oil terminals
• Loading and unloading systems
• Crude oil transfer
• Fuel oil transfer
• Lubricating oil
• Bitumen and asphalt
• Tar
• Polymers
• Resins
• Chemical processing
• Aggressive and toxic liquids

Why Choose Twin Screw Pumps?

Twin Screw Pumps provide a versatile positive-displacement solution for difficult process fluids that require controlled, low-pulsation transfer across varying viscosities and operating conditions.

Their twin screw hydraulic design makes them particularly suitable for hydrocarbons and high-viscosity products while also allowing selected configurations to handle entrained gas, solids and multiphase fluids.

Magnetic-drive designs provide enhanced process containment where leakage control is critical, while mechanical-seal configurations provide extensive flexibility in sealing arrangements and larger single- or double-volute hydraulic configurations.

For industrial operators, this provides flexible fluid handling, low-pulsation operation, strong high-viscosity performance and multiple containment and sealing options for demanding process applications.
