Common Problems with Becker T4.25DV Vacuum & Pressure Pumps
The Becker T4.25DV is a compact combined dry running rotary vane vacuum and pressure pump. It is commonly used where print, paper handling and packaging machinery need both suction and blast air from one compact pump.
Common faults include:
- Worn carbon vanes 90134900007 WN124-162
- Weak suction or reduced blast pressure
- Broken or chipped vanes
- Blocked filters – 909518 and 909521
- Overheating
- Excessive noise or vibration
- Low airflow
- Bearing wear
- Paper dust or spray powder contamination
- Poor sheet separation, feed or delivery performance
In printing and print finishing applications, poor machine performance is often caused by worn vanes, blocked filtration, leaking pipework or contamination reducing airflow through the pump.
Becker T4.25DV Technical Specifications
The Becker T4.25DV is a compact dry running rotary vane combined vacuum and pressure pump designed for small to medium print, paper handling and packaging machinery where both suction and blast air are required from one reliable unit.
With a nominal volume flow of approximately 25 m³/h at 50Hz and 30 m³/h at 60Hz, the Becker T4.25DV offers a useful step up in airflow for suction and blast applications while remaining compact and oil-free.

Typical Applications for the Becker T4.25DV
The Becker T4.25DV is used on machinery that requires both vacuum suction and pressure air. In print and paper industries, these pumps are often referred to as “suction and blast” pumps.
- Printing presses and print finishing machinery
- Paper handling systems
- Sheet separation and feeder systems
- Small suction and blast duties
- Packaging machinery
- Labelling and converting machinery
- Vacuum pick-up and light handling
- Blow-off and separation duties
- General light industrial machinery
Maintenance Tips for the Becker T4.25DV
The Becker T4.25DV is compact, but maintenance still matters. In print and paper environments, paper dust, spray powder and small debris can restrict airflow and reduce both suction and blast performance.
Useful maintenance checks include:
- Inspect filters regularly and replace blocked or contaminated elements
- Monitor both suction and blast pressure performance
- Check for changes in noise, vibration or running temperature
- Keep cooling air paths clear
- Inspect carbon vane wear as part of planned servicing
- Check suction and pressure pipework for leaks or restrictions
- Keep paper dust and debris away from the pump intake area where possible
- Investigate sudden performance drops before they lead to more costly repairs
For printing, print finishing and paper handling applications, filter condition is especially important. A restricted filter can reduce airflow and affect both suction feed and pressure/blast functions.

Repair or Replace a Becker T4.25DV?
Many Becker T4.25DV pumps can be repaired economically if vane wear, blocked filters or bearing issues are identified before major internal damage occurs.
Repair is often suitable where the pump has:
- worn vanes
- blocked filters
- weak suction or blast performance
- noisy bearings
- minor contamination
- serviceable wear components
Replacement may be more cost effective where the pump has:
- severe internal scoring
- catastrophic vane failure
- motor failure
- excessive running hours
- repeated breakdown history
- major rotor or cylinder damage
VacAir engineers can advise whether servicing, overhaul or replacement is the best option for your application and downtime requirements. We can also advise on refurbished vacuum pumps where available.

Why Consider a DVP Alternative?
For some applications, a DVP dry running rotary vane vacuum and pressure pump may provide a practical alternative to a Becker T4.25DV, particularly where price, availability or replacement strategy is important.
The Becker T-series remains a well-proven compact pump design, especially in printing, print finishing and paper handling applications where both vacuum and pressure are required. However, some customers also consider DVP pumps where they need a competitively priced industrial solution with reliable oil-free operation and strong long-term support.
DVP dry running rotary vane pumps, available through VacAir or our sister company Vacuum Pumps UK, use carbon vane technology to provide dependable oil-free suction and pressure air for industrial machinery.
Key advantages of considering a DVP alternative can include:
- Reliable oil-free operation
- Dry running carbon vane technology
- Combined suction and pressure options
- Competitive replacement option for existing pumps
- Good availability of spare parts and servicing support
- Suitable for printing, packaging and paper handling applications
VacAir Superstore can advise whether retaining a Becker T4.25DV, repairing the existing unit or considering an alternative pump is the most suitable choice for your application.
