DVP SA3TV Discontinued Dry-Running Rotary Vane Vacuum Pump
The DVP SA3TV, also known as the DVP SA.3TV, was the specially sealed version of the compact dry-running rotary vane vacuum pump for industrial machinery requiring clean, oil-free vacuum.
Its special construction and FKM gaskets provided improved leak tightness, while the lightweight monoblock design allowed the pump to be installed inside machinery where available space was limited but sufficient ventilation was provided.
The DVP SA3TV is discontinued, but Vacuum Pumps UK can assist with vanes, service kits, spare parts, repairs and selection of the nearest current DVP alternative.
Do you have an existing DVP SA3TV fitted to a machine?
Send us the complete pump model, serial number, a clear photograph of the nameplate and details of the application.
We can check parts availability, assess repair options and compare the current DVP SC5 against the original installation.

The DVP SA3TV Has Been Discontinued
The DVP SA3TV is no longer included in the current DVP production range. However, 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, seals, gaskets, individual spare parts and workshop repair support.
The nearest current DVP dry-running rotary vane alternative is the DVP SC5. The SC5 also uses FKM sealing and reaches the same stated ultimate vacuum of 120 mbar absolute, while providing increased pumping capacity.
The SC5 should not automatically be treated as a direct drop-in replacement. Overall dimensions, mounting points, inlet connection, electrical supply, available ventilation and machine operating duty should be confirmed before ordering.
DVP SA3TV Overview
The DVP SA3TV was a small industrial dry-running rotary vane vacuum pump designed to provide oil-free vacuum from a compact and lightweight unit.
The pump used a monoblock construction in which the rotor was assembled directly onto the motor shaft. This reduced the number of separate drive components and helped keep the overall dimensions and weight low.
The main pump components were manufactured largely from lightweight alloys, allowing the SA3TV to be installed within machinery where space was restricted, provided adequate ventilation remained available around the pump.
The SA3TV provided a nominal inlet capacity of 3 m³/h at 50Hz and 3.3 m³/h at 60Hz. Its stated ultimate vacuum was 120 mbar absolute.
Unlike the standard SA3, the TV version incorporated a special pump design together with FKM gaskets to provide improved leak tightness.
What Was Different About the SA3TV?
The SA3TV was not simply an alternative model name for the standard SA3. It was the specially sealed version of the pump.
DVP used a particular pump design combined with FKM gaskets to provide a high level of leak tightness. This made the TV version appropriate where leakage through the pump or its seals needed to be kept to a minimum.
The SA3TV also used a threaded G 1/8-inch inlet connection, whereas the original technical table listed a Ø9 inlet for the standard SA3.
When identifying replacement parts or a new pump, it is therefore important to state the complete SA3TV or SA.3TV designation rather than referring only to an SA3.

Typical SA3TV Applications
The precise original machine duty should always be checked. Compact sealed dry-running vacuum pumps of this size are commonly used where modest oil-free airflow and good pump leak tightness are required.
Small suction lifting and handling equipment
Printing and paper handling machinery
Automatic feeders and bookbinding machinery
Money counting and document handling equipment
Sampling and analysis equipment
Small vacuum pressing equipment
Compact OEM machinery
Equipment requiring low-capacity oil-free vacuum
Key DVP SA3TV Features
Leak-Tight TV Design
The special TV construction combined with FKM gaskets provided improved leak tightness compared with the standard SA3 version.
Compact Monoblock Design
The rotor was assembled directly onto the motor shaft, helping reduce the overall dimensions and number of separate drive components.
Oil-Free Operation
The dry-running pumping arrangement provided vacuum without requiring lubricating oil inside the pumping chamber.
Lightweight Construction
The use of lightweight alloys helped keep the complete pump weight to approximately 5 kg.
Identifying an SA3 or SA3TV
The SA3 and SA3TV shared the same nominal pumping capacity, ultimate vacuum, motor ratings, operating speeds and general dimensions.
The complete model designation is therefore important when ordering parts or selecting a replacement. The original catalogue code for the SA3TV was 9901017, while the technical information listed a G 1/8-inch threaded inlet.
The SA3TV designation also confirms that the pump was the specially sealed version using FKM gaskets.
Send us a clear photograph of the pump and nameplate where the model plate is missing, damaged or difficult to read. We can assist with identification before supplying parts.
SA3TV 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.
Because leak tightness was a particular feature of the SA3TV, the condition and correct specification of its seals and gaskets should also be considered during maintenance or overhaul.
Vacuum Pumps UK and our sister company, VacAir Superstore, can assist with replacement vanes, seals, gaskets and service components for the DVP SA3TV, subject to confirmation of current availability.
Should You Repair or Replace a DVP SA3TV?
A discontinued SA3TV that has gradually lost performance may only require replacement vanes, seals, gaskets or workshop attention rather than complete replacement.
Repair may remain economical where the pump body, rotor, motor and main internal surfaces are still serviceable and the required parts remain available.
Replacement becomes more attractive where the pump has suffered major internal damage, the motor has failed, the leak-tight construction can no longer be restored or repeated breakdowns are affecting production reliability.
We can review both options and advise whether servicing the existing SA3TV or installing a current DVP pump offers the better long-term result.
Current DVP Alternative: SC5
The DVP SC5 is the nearest current mains-powered DVP dry-running rotary vane model to the discontinued SA3TV.
The SC5 also uses FKM sealing and provides an ultimate vacuum of 120 mbar absolute. Its nominal pumping capacity is increased to 5 m³/h at 50Hz and 6 m³/h at 60Hz.
| Specification | DVP SA3TV | DVP SC5 |
| Product status | Discontinued | Current model |
| Nominal capacity at 50Hz | 3 m³/h | 5 m³/h |
| Nominal capacity at 60Hz | 3.3 m³/h | 6 m³/h |
| Ultimate vacuum | 120 mbar absolute | 120 mbar absolute |
| Sealing | Special design with FKM gaskets | FKM sealing |
| Pump technology | Dry-running rotary vane | Dry-running rotary vane |
| Installation requirement | Original installation | Compatibility check required |
The SC5 has a higher pumping capacity than the original SA3TV. This may provide faster evacuation or additional airflow, but suitability should still be assessed against the machine and its normal operating requirements.
Before replacement, we recommend checking the voltage and phase, motor rating, overall dimensions, mounting arrangement, inlet connection, ventilation and required level of system leak tightness.
