The DVP SB6 Has Been Discontinued

The DVP SB6 is no longer included in the current DVP production range. An existing pump may still be suitable for continued service where its main components remain in serviceable condition and the necessary replacement parts are available.

Vacuum Pumps UK can assist with replacement vanes, genuine service kits, filters, seals, gaskets, individual spare parts and workshop repair support.

The DVP SC8 is the natural current capacity replacement. The smaller DVP SC5 may also be suitable where its lower airflow is sufficient for the machinery.

Neither pump should automatically be treated as a direct drop-in replacement. Airflow, ultimate vacuum, overall dimensions, mounting points, inlet connection, electrical supply, ventilation and machine duty should be checked first.

DVP SB6 Overview

The DVP SB6 was a compact industrial dry-running rotary vane vacuum pump designed to provide oil-free vacuum from a relatively small and lightweight unit.

The pump used a monoblock construction with the rotor assembled directly onto the motor shaft. This reduced the number of separate drive components and helped limit the overall dimensions and weight.

The pump was manufactured mainly from lightweight alloys and could be installed within machinery where available space was restricted, provided that good ventilation remained available around the unit.

Pump cooling was provided by an integral motor fan. A protective inlet filter and exhaust silencer were included as standard equipment on the SB6.

The SB6 provided a nominal inlet capacity of 6 m³/h at 50Hz and 7 m³/h at 60Hz, with an ultimate vacuum of 120 mbar absolute.

Original DVP SB6 Technical Data

Technical details should be checked against the individual pump nameplate because electrical versions and production revisions may differ.

Key DVP SB6 Features

SB6 Vanes and Planned Maintenance

The vanes within a dry-running rotary vane vacuum pump are wearing components that gradually shorten through normal contact with the internal pumping chamber.

Vane condition should be assessed according to running hours, operating temperature, inlet cleanliness, duty cycle and the amount of dust or debris entering the pump.

A gradual reduction in vacuum performance, reduced airflow, increased noise or hotter operation may indicate worn vanes, restricted filtration, leakage or internal pump wear.

Vacuum Pumps UK and our sister company, VacAir Superstore, can assist with replacement vanes, filters, seals, gaskets and service components for the DVP SB6, subject to confirmation of current availability.

Should You Repair or Replace a DVP SB6?

A discontinued SB6 that has gradually lost performance may only require replacement vanes, filtration, seals or workshop attention rather than complete replacement.

Repair may remain economical where the pump body, rotor, motor and main internal surfaces are serviceable and the required parts remain available.

Replacement becomes more attractive where the pump has suffered major internal damage, the motor has failed, repair parts are unavailable or repeated breakdowns are affecting production reliability.

We can review both options and advise whether servicing the existing SB6 or installing a current DVP pump offers the better long-term result.

Current DVP Alternatives: SC8 and SC5

The DVP SC8 is the natural current capacity replacement for the discontinued SB6. It provides increased airflow of 8 m³/h at 50Hz and 9 m³/h at 60Hz, using the same 0.25 / 0.30 kW motor power.

The SC8 has a stated ultimate vacuum of 150 mbar absolute, compared with 120 mbar absolute for the SB6. The application must therefore be checked where the original machine depends upon reaching pressures below 150 mbar absolute.

The smaller DVP SC5 may be considered where 5 m³/h at 50Hz and 6 m³/h at 60Hz are sufficient. It retains the 120 mbar absolute ultimate vacuum of the original SB6, but provides less airflow.

Before replacement, we recommend checking the required airflow, normal operating vacuum, voltage and phase, motor rating, overall dimensions, mounting arrangement, inlet connection, ventilation and duty cycle.

Need Help Confirming the Correct SB6 Replacement?

Send us a clear photograph of the SB6 nameplate together with details of the machine and how the pump is being used.

We can compare the original airflow, ultimate vacuum, voltage, phase, motor power, inlet connection, mounting and available installation space before recommending the most suitable current model.

Send us the SB6 details and information about the application.

DVP SB6 Frequently Asked Questions

Is the DVP SB6 still manufactured?

No. The DVP SB6 is a discontinued dry-running rotary vane vacuum pump and is no longer included in the current DVP production range.

Is the pump also known as the DVP SB.6?

Yes. SB6 and SB.6 are alternative ways in which the model may appear in manuals, records and machinery documentation.

What pumping capacity did the SB6 provide?

The nominal pumping capacity was 6 m³/h at 50Hz and 7 m³/h at 60Hz.

What ultimate vacuum could the DVP SB6 achieve?

The stated ultimate vacuum was 120 mbar absolute.

What motor power did the SB6 use?

The listed motor power was 0.25 kW at 50Hz and 0.30 kW at 60Hz.

Was the DVP SB6 oil free?

Yes. The SB6 was a dry-running rotary vane pump and did not require lubricating oil inside the pumping chamber.

Did the SB6 include an inlet filter and exhaust silencer?

Yes. The original DVP information listed a protective inlet filter and an exhaust silencer as standard equipment on the SB6.

Can an existing DVP SB6 still be repaired?

Possibly. Repair will depend upon the condition of the pump, the extent of internal wear and the availability of the necessary vanes and service components.

Are replacement vanes and service kits available?

Replacement vanes and genuine service components may remain available. The complete model and serial number should be checked before parts are ordered.

What is the natural current replacement for the DVP SB6?

The DVP SC8 is the natural current capacity replacement, providing 8 m³/h at 50Hz and 9 m³/h at 60Hz. Its ultimate vacuum is 150 mbar absolute, so the required operating vacuum must be checked.

Could the DVP SC5 replace an SB6?

The SC5 may be suitable where its lower capacity of 5 m³/h at 50Hz and 6 m³/h at 60Hz is sufficient. It matches the SB6 ultimate vacuum of 120 mbar absolute.

Are the SC8 or SC5 direct drop-in replacements?

No direct interchange should be assumed. Dimensions, mounting, connections, electrical specification, airflow, final pressure, ventilation and machine duty should be checked before ordering.

Can you inspect my existing SB6?

Yes. Send us photographs of the pump and nameplate together with details of the fault. We can advise whether parts, workshop inspection, repair or replacement are likely to be the most appropriate route.
