Busch SECO SV1140C Vacuum Pump
The Busch SECO SV1140C is a dry-running rotary vane vacuum pump developed for machine builders and end users needing a compact dry-running rotary vane pump for regular production duty.
Vacuum Pumps UK can assist with Busch pump supply, replacement advice and application checks. If the installation does not require the exact Busch model, the DVP SC140 can be assessed as a practical oil-free alternative.

Busch SECO SV1140C Overview
The Busch SECO SV1140C uses dry-running rotary vane technology, with self-lubricating carbon vanes operating without lubricating oil inside the compression chamber. That makes this type of pump particularly useful where an oil-free vacuum source is required.
At 50Hz the pump delivers 140 m³/h, increasing to 168 m³/h at 60Hz. Its stated ultimate pressure is 100 mbar absolute.
Unlike an oil-lubricated rotary vane pump, routine maintenance centres on vane condition, inlet filtration, cooling and general internal cleanliness. Carbon vanes are a normal wearing component and should be inspected before they reach their minimum permissible length.

Typical Applications for the Busch SECO SV1140C
Dry-running vane pumps of this size are commonly used where clean suction and dependable repetitive operation are required.
› food and packaging equipment where dry air is suitable
› book-binding and paper handling machinery
› vacuum hold-down applications
› sampling and analysis equipment
› general industrial suction duties
DVP SC140
Oil-free dry-running alternative
Comparable DVP Alternative
Consider the DVP SC140
Where an exact Busch replacement is not essential, the DVP SC140 can be considered as a slightly lower in capacity dry-running rotary vane alternative.
The DVP SC140 provides 130 / 150 m³/h at 50Hz / 60Hz and has a stated final pressure of 120 mbar absolute. Compared with the Busch pump, this gives a somewhat shallower stated ultimate vacuum.
Both technologies use oil-free rotary vane operation with carbon vanes, but the mounting arrangement, inlet and exhaust connections, motor details, cooling requirements and permitted operating pressure must be checked before changing pump model.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.

| Busch SECO SV1140C | 140 / 168 m³/h | 100 mbar abs. | 4.0 / 5.5 kW |
| DVP SC140 | 130 / 150 m³/h | 120 mbar abs. | 4.0 / 4.4 kW |
Busch SECO SV1140C Carbon Vanes, Filters, Spares and Repair
Many Busch SECO and TINY dry-running pumps remain in productive service for years, so maintaining the existing pump can be a sensible option. Our sister company VacAir Superstore supplies replacement components and provides workshop service and repair support for Busch dry-running rotary vane pumps.
Carbon vane condition is particularly important. Excessive vane wear can reduce vacuum performance and, if ignored, may result in damage to the rotor, cylinder or end plates.
Carbon Vanes
Replacement Busch carbon vanes for planned maintenance and overhaul work.
Filters
Inlet filters and replacement elements to help prevent dust and debris reaching the pump chamber.
Spare Parts
Service components, gaskets, seals and other replacement parts for Busch dry-running pumps.
Service & Repair
Inspection, vane replacement, fault diagnosis and workshop repair for worn or damaged pumps.
Busch SECO SV1140C Frequently Asked Questions
Is the Busch SECO SV1140C an oil-free vacuum pump?
Yes. It is a dry-running rotary vane vacuum pump that uses self-lubricating carbon vanes rather than oil in the pumping chamber.
What is the pumping speed?
The stated nominal capacity is 140 m³/h at 50Hz and 168 m³/h at 60Hz.
What vacuum level does it reach?
The stated ultimate pressure is 100 mbar absolute.
What DVP alternative can be considered?
The DVP SC140 is the primary alternative selected by pumping capacity and dry-running technology.
Do carbon vanes need replacing?
Yes. Carbon vanes are a wear component and should be inspected as part of planned maintenance, with replacement before they reach their minimum permitted length.
Can an existing Busch SECO SV1140C be repaired?
Often, yes. VacAir can inspect the pump, replace vanes and service parts, and assess whether repair or replacement is the better option.
