Becker VT 4.25 Overview
The Becker VT 4.25 is part of Becker’s established range of dry-running rotary vane vacuum pumps.
It provides a nominal pumping speed of 25 m³/h at 50Hz and 30 m³/h at 60Hz, with a stated ultimate pressure of 150 / 150 mbar absolute.
The pump uses self-lubricating carbon vanes rather than oil within the pumping chamber. This supports clean vacuum generation and avoids routine lubricating-oil changes, although the carbon vanes remain a normal wear component that requires planned inspection.
Vacuum Pumps UK can assist with the supply of a new Becker VT 4.25 where the original model and performance need to be retained.

Becker VT 4.25 Pump Features
Oil-Free Pumping Chamber
The pumping chamber operates without lubricating oil, supporting clean vacuum generation.
Carbon Vane Technology
Self-lubricating carbon vanes form the working chambers and gradually wear during normal operation.
Continuous Duty Capability
The pump is intended for continuous service when correctly selected, installed, ventilated and maintained.
Clean Inlet Air Required
Effective inlet filtration helps protect the vanes and pump chamber from dust and contamination.
Straightforward Maintenance
Planned vane and filter inspection can help prevent loss of performance and avoid internal damage.
Industrial Applications
Dry-running rotary vane technology is widely used for packaging, printing, handling, woodworking and automation.
Typical Becker VT 4.25 Applications
The Becker VT 4.25 is commonly used where dependable oil-free rotary vane vacuum performance is required.
› Packaging machinery
› Woodworking machines
› Vacuum presses
› Automated handling equipment
› Printing and paper machinery
› Pneumatic conveying

DVP SC25
25 / 29 m³/h dry-running vacuum pump
Comparable DVP Alternative
Consider the DVP SC25
Where an exact Becker replacement is not essential, the DVP SC25 may provide a suitable and cost-effective alternative to the Becker VT 4.25.
The SC25 matches the 50Hz pumping capacity and is only slightly lower at 60Hz, while providing a deeper stated ultimate vacuum.
The DVP SC25 provides 25 m³/h at 50Hz and 29 m³/h at 60Hz, with a stated ultimate vacuum of 120 / 120 mbar absolute.
The SC25 has a compact industrial monobloc design with a protective inlet filter, outlet silencer and rear centrifugal cooling fan.
Its dry-running design uses self-lubricating carbon or graphite vanes and does not require oil inside the pumping chamber. The vanes remain a normal service item and should be inspected and replaced before reaching their minimum permitted length.
Mounting dimensions, inlet position, connection size, motor voltage, operating vacuum and the process duty must be checked before changing pump model.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
Becker VT 4.25 and DVP SC25 Comparison
The comparison below shows the principal technical figures. Final suitability should be checked against the machine, application and installation requirements.
| Specification | Becker VT 4.25 | DVP SC25 |
| Pump Technology | Dry-running rotary vane | Dry-running rotary vane |
| Nominal Capacity 50Hz | 25 m³/h | 25 m³/h |
| Nominal Capacity 60Hz | 30 m³/h | 29 m³/h |
| Maximum Vacuum 50Hz | 150 mbar absolute | 120 mbar absolute |
| Maximum Vacuum 60Hz | 150 mbar absolute | 120 mbar absolute |
| Motor Power 50Hz | 0.75 kW | 0.75 kW |
| Motor Power 60Hz | 0.90 kW | 0.90 kW |
| Lubrication | No oil in pumping chamber | No oil in pumping chamber |
Important: Lower mbar absolute figures indicate a deeper vacuum. Capacity alone is not sufficient for replacement selection; dimensions, connections, motor supply, duty cycle, process contamination and required operating vacuum must also be checked.
Why Consider a DVP Dry-Running Pump?
Capacity Matching
The DVP option has been selected by comparing the nominal pumping speed at both 50Hz and 60Hz.
Oil-Free Operation
Self-lubricating carbon or graphite vanes avoid oil inside the pumping chamber and support clean vacuum generation.
European Manufacture
DVP dry-running rotary vane vacuum pumps are manufactured in Italy and supported by the UK and Ireland Master Agent.
Parts and Support
Genuine DVP vanes, filters, service parts and technical support are available through Vacuum Pumps UK.
