Elmo Rietschle VTN41 Vacuum Pump
The VTN41 is the larger model in the VTN dry-running group, intended for machinery that needs substantially more airflow than the smaller VTN pumps while retaining oil-free rotary vane operation.
Vacuum Pumps UK can supply new Elmo Rietschle VTN41 vacuum pumps and provide technical advice for existing machinery, planned replacement work and new installations.
Where retaining the exact Elmo Rietschle model is not essential, the DVP SC40 can also be assessed against the required airflow, vacuum level and installation details.

Elmo Rietschle VTN41 Overview
The Elmo Rietschle VTN41 is part of the manufacturer’s dry-running rotary vane vacuum pump range. It provides 42 m³/h at 50Hz and 50.4 m³/h at 60Hz, with a stated maximum vacuum of 150 / 150 mbar absolute.
For users moving up from smaller dry-vane pumps, the VTN41 offers increased pumping speed without changing the basic oil-free rotary vane principle.
The pumping chamber operates without lubricating oil. Instead, self-lubricating carbon vanes slide within the cylinder to create the changing chamber volume required for vacuum generation. This avoids routine vacuum-pump oil changes and helps provide a clean, dry vacuum source.
Carbon vanes are nevertheless normal wearing components. Their condition should be checked at appropriate service intervals because excessive wear can reduce pumping performance and, if allowed to continue, may result in damage to the rotor, cylinder or end plates.
The listed three-phase motor power is 1.5 kW at 50Hz and 1.8 kW at 60Hz. Voltage, phase, frequency and motor configuration should be confirmed from the individual pump nameplate before ordering.
Vacuum Pumps UK can assist with new pump supply and replacement selection, while our sister company VacAir Superstore can support existing Elmo Rietschle pumps with carbon vanes, filters, spare parts, servicing and workshop repair.

Elmo Rietschle VTN41 Pump Features
Dry Running Rotary Vane
Self-lubricating carbon vanes provide oil-free vacuum generation without process oil inside the pumping chamber.
Industrial Vacuum Duty
The VTN41 is intended for industrial machinery requiring dependable dry vacuum and sustained airflow.
Oil-Free Pumping Chamber
Dry vane technology avoids lubricating oil in the compression chamber and removes routine vacuum-pump oil changes.
Carbon Vane Maintenance
The carbon vanes are service-wear components and should be inspected before they reach their permitted minimum length.
Inlet Protection
Effective inlet filtration helps prevent abrasive dust and debris from accelerating vane and cylinder wear.
Serviceable Construction
Vanes, filters, bearings and other wear components can be inspected and replaced as part of planned maintenance or overhaul.
Typical Elmo Rietschle VTN41 Applications
Dry-running rotary vane pumps are used where dependable airflow and oil-free vacuum are required. The VTN41 can be considered for applications such as:
› Packaging machinery
› Printing and converting equipment
› Woodworking machines
› Vacuum presses
› Automated handling systems
› Pneumatic conveying
› Vacuum clamping
› Plastics processing
› Production machinery
› General industrial vacuum
Actual suitability depends on system volume, leakage rate, required operating pressure, evacuation time and the material being handled. Processes involving liquids, heavy dust or aggressive vapours should be reviewed before selecting a dry carbon-vane pump.
New Elmo Rietschle VTN41 Vacuum Pump Supply
Vacuum Pumps UK can supply new Elmo Rietschle VTN41 vacuum pumps for existing machinery, planned replacement work and new industrial installations.
Where the original specification needs to be retained, send us the complete pump nameplate and we can check the motor, voltage, frequency and connection details before quotation.
For replacement projects we can also discuss the actual application rather than simply matching the model number. This is useful where a current pump has been oversized, the machine duty has changed or another dry-running pump may provide a practical alternative.
Contact us for current price, availability and application advice.
DVP SC40
40 / 48 m³/h dry-running vacuum pump
Comparable DVP Alternative
Consider the DVP SC40
Where an exact Elmo Rietschle replacement is not essential, the DVP SC40 can be considered as an alternative to the Elmo Rietschle VTN41.
The SC40 is a close capacity comparison to the VTN41. Its stated final pressure is 120 mbar absolute rather than 150 mbar absolute, giving the DVP pump a deeper published vacuum.
The DVP SC40 provides 40 m³/h at 50Hz and 48 m³/h at 60Hz, with a stated maximum vacuum of 120 / 120 mbar absolute. Motor power is 1.5 / 1.8 kW at 50Hz / 60Hz.
The DVP pump also uses dry-running rotary vane technology with durable graphite vanes and no lubricating oil inside the pumping chamber. The vanes remain a normal service item and should be inspected at appropriate intervals.
Mounting dimensions, inlet and exhaust positions, connection sizes, motor voltage, electrical frequency, operating vacuum and the process duty must all be checked before changing pump model.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
Elmo Rietschle VTN41 and DVP SC40 Comparison
The figures below show the principal differences between the Elmo Rietschle pump and the DVP option. The DVP model should be selected around the actual application rather than treated as a dimensional drop-in replacement.
| Specification | Elmo Rietschle VTN41 | DVP SC40 |
| Pump Technology | Dry-running rotary vane | Dry-running rotary vane |
| Nominal Capacity 50Hz | 42 m³/h | 40 m³/h |
| Nominal Capacity 60Hz | 50.4 m³/h | 48 m³/h |
| Maximum Vacuum 50Hz | 150 mbar absolute | 120 mbar absolute |
| Maximum Vacuum 60Hz | 150 mbar absolute | 120 mbar absolute |
| Motor Power 50Hz | 1.5 kW | 1.5 kW |
| Motor Power 60Hz | 1.8 kW | 1.8 kW |
| Lubrication | No oil in pumping chamber | No oil in pumping chamber |
Important: Lower mbar absolute figures indicate a deeper vacuum. Capacity alone does not determine suitability; 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, rather than simply choosing the nearest model number.
Oil-Free Operation
The pumping chamber operates without lubricating oil, making DVP dry-running rotary vane pumps suitable for clean industrial vacuum duties.
Graphite Vanes
Durable graphite vanes provide the working seal. They remain a service component but can be inspected and replaced as part of planned maintenance.
