s a professional screw pump manufacturer, Vigorous specializes in twin-screw pumps. It focuses on R&D and manufacturing, offering efficient fluid transfer solutions for various industries. Its twin-screw pumps stand out for unique design and strong performance, excelling in high-viscosity media transfer and stable operation under complex conditions.
Twin-Screw Pumps: Efficient Tools in the Screw Pump Family
Twin-screw pumps are key in the screw pump family. Their strength lies in smart design and sound working principles, balancing efficiency and adaptability.
Structure: Non-Contact Design for Longer Life
Vigorous’ twin-screw pumps have two intermeshing rotors and a pump casing. Key design features include:
- No metal friction: The driving screw turns the driven screw via a synchronous gear. They rotate in opposite directions. No metal touches between screws or between screws and the casing. This cuts wear and extends life.
- Strong rotor shafts: Rotors are made from high-strength alloy steel. Vigorous uses advanced heat treatment and flexible processing. This keeps rotors stable under high pressure (up to 30MPa) and extreme temperatures (-40℃ to 120℃). They resist deformation 40% better than regular rotors.
Working Principle: Closed Chambers for Stable Transfer
Twin-screw pumps work on the “positive displacement” principle. They move fluids smoothly and efficiently:
- As screws spin in opposite directions, they form closed chambers. Fluid enters the inlet and splits into two streams. These streams move from both ends of the screws toward the center. Then they exit through the outlet.
- This “two-way flow” design balances hydraulic forces. It reduces pressure spikes and slug flow impact, keeping operation steady.
Vigorous Twin-Screw Pumps: Key Advantages
As a focused screw pump manufacturer, Vigorous’ twin-screw pumps offer unique benefits:
Handles Both High and Low Viscosity Fluids
Vigorous’ twin-screw pumps work with a wide range of viscosities. They handle fluids from 1cSt (like water) to 100,000cSt (like thick crude oil). Even with high-wax, thick crude, they keep a steady flow—solving the efficiency drop issue of regular pumps.
Efficient and Energy-Saving
These pumps have optimized screw shapes and fluid channels. They are over 20% more efficient than traditional centrifugal pumps in oil pipeline projects. This cuts energy use by 15-25% for the same transfer volume, lowering long-term costs.
Stable Under Tough Conditions
The “hydraulic balance” and “no metal friction” design boost reliability:
- They handle slug flow (like flow swings in oil-gas mix transfer). The chambers buffer impacts, avoiding shutdowns from sudden pressure changes.
Vigorous: Strengths as a Screw Pump Manufacturer
