Busch SECO SV series

The Seco rotary vane vacuum pumps are compact, reliable and powerful dry-running vacuum pumps for numerous industrial applications. Thanks to oil-free vacuum generation and the energy-efficient drive, they allow economical, safe and low-maintenance operation.

The robust, self-lubricating rotor vanes made of special graphite and the lifetime-lubricated bearings ensure high operational reliability and long service lives. Thanks to their compact design, the pumps can be installed flexibly and integrated easily into existing systems.

The Seco series also stands out for its particularly service-friendly construction. Apart from regular filter changes and replacement of the rotor vanes, no time-consuming maintenance work is required.

Standard operating conditions and performance

Ambient temperature and intake air temperature: 0 to 40 °C

Nominal pumping speed: approx. 3 to 100 m³/h (at 50 Hz), depending on the model

Achievable ultimate vacuum: down to approx. 100 mbar (absolute), depending on the model

Maximum permissible operating pressure: depending on the model and operating mode

Designed for dry and oil-free vacuum applications

Operating principle

The Busch SECO SV series works on a dry rotary vane principle and thus allows reliable, oil-free vacuum operation. During rotation, the eccentrically arranged rotor with its vanes creates continuously changing working chambers in which the air drawn in is compressed and then discharged.

The robust construction and the high-quality, low-wear components allow reliable continuous operation with low maintenance requirements. Dry operation means there is no oil contamination in the pumped medium, which makes the SECO SV particularly suitable for applications that require clean and oil-free vacuum air. The compact design and the proven technology also ensure a long service life and economical operation.

Features and benefits of the SECO SV series

The SECO SV series was developed for reliable and efficient vacuum generation. The dry rotary vane principle allows constant vacuum performance with low operating effort. This makes the series particularly suitable for applications where economical and reliable continuous operation is required.

The compact and robust construction of the SECO SV ensures high operational reliability and a long service life. The proven rotary vane technology is designed for continuous use and provides reliable vacuum generation even under demanding operating conditions.

As dry-running vacuum pumps, the SECO SV models require no oil in the pump chamber. This reduces the risk of oil contamination of the pumped medium and allows clean vacuum operation – ideal for applications that require an oil-free vacuum.

With the SECO SV series, Busch offers a proven solution for reliable, efficient and clean vacuum generation. The dry-running vacuum pumps are characterised by oil-free operation, a robust construction, low maintenance requirements and a long service life. Thanks to their compact design and versatility, they are ideally suited to numerous industrial vacuum applications and allow economical and reliable operation.
