Becker VT4.25 Dry Vacuum Pump - High Performance Oil-Free Vacuum Pump Applications & Features
The Becker VT4.25 dry vacuum pump delivers 25m³/h flow rate and 150mbar ultimate vacuum, with oil-free design suitable for electronics, semiconductor, pharmaceutical industries, featuring low vibration, smooth operation and easy maintenance.
The Becker VT4.25 dry vacuum pump is an efficient, clean oil-free vacuum solution designed for applications requiring stable vacuum performance with sensitivity to oil contamination. This pump is widely used across multiple industries for its exceptional performance and reliability.
High pumping speed across wide pressure range: Maintains stable pumping speed across broad operating pressure range
Excellent operational stability: Precisely geometrically symmetrical rotors ensure low vibration and smooth operation
Oil-free clean design: No lubrication required in pumping chamber, eliminating oil vapor contamination
Energy efficient: No direct contact between rotors minimizes friction loss and reduces drive power
Simple and durable structure: Compact design without exhaust valves, easy maintenance
Strong environmental adaptability: Insensitive to dust and water vapor in pumped gases
Special rotor design: Complex curved cylindrical rotors optimize gas flow path
Note: This model has relatively low compression ratio and less effective for hydrogen pumping, with high precision requirements for rotor machining

1: Why is the Becker VT4.25 called a "dry" vacuum pump?
Because it doesn't require oil for sealing or lubrication, with completely oil-free pumping chamber that prevents oil vapor contamination to vacuum systems and processed products.
2: What maintenance does this industrial vacuum pump require?
Regular inspection of intake filters, motor operation status and system sealing. The oil-free design eliminates oil changes and related maintenance.
3: Is the VT4.25 oil-free vacuum pump suitable for continuous operation?
Yes, this pump is designed for long-term continuous operation, though proper rest cycles per operation manual are recommended.
4: Why is this Becker vacuum pump less effective for hydrogen pumping?
Due to the relatively low compression ratio of dry vacuum pumps and hydrogen's small molecular weight and high diffusibility, hydrogen pumping efficiency is comparatively lower.
5: How to choose between single-phase (220V) and three-phase (380V) versions for packaging machine vacuum pumps?
Select based on your site power configuration. Three-phase version is slightly more energy efficient (0.75kW vs 0.8kW), while single-phase is better for small locations.
6: What is the noise level of semiconductor vacuum equipment?
The noise level is 62dB, relatively quiet for industrial environments, typically requiring no additional soundproofing measures.
7: How often should filters be replaced in pharmaceutical vacuum systems?
Depends on dust content in working environment, generally recommended every 3-6 months for inspection/replacement, more frequently in harsh environments.
8: Can environmental vacuum technology pumps handle corrosive gases?
Standard models aren't suitable for highly corrosive gases. For special requirements, consult manufacturer about material compatibility.
9: What does 150mbar ultimate vacuum mean for medical vacuum devices?
It indicates the minimum absolute pressure the pump can achieve (150 millibar ≈ 112.5Torr), an important parameter for evaluating pump performance.
10: Is the 26kg weight of woodworking vacuum cup pumps easy for installation?
Yes, the compact and lightweight design makes VT4.25 easy to install in various positions, with basic installation achievable by one person.
