Sound insulation for vacuum pumps

Thanks to these sound protection hoods, the noise disturbance at the workplace is reduced to a minimum.
With the various models almost any device can be insulated.

The SSH Series

These sound protection hoods are designed for the insulation of backing pumps, as they are often used in analytical laboratories. Due to the variable concept and the different types, almost all pumps can be insulated.

Noise protection in the workplace is becoming increasingly important. Whereas laboratories used to be rather quiet workplaces, they now contain a large number of devices that can cause immense noise levels. The most common sources are vacuum pumps, ultrasonic cleaning devices and water coolers. In the worst case, the noise can have a detrimental effect on health. But even lower noise levels significantly impair the ability to concentrate. Especially in scientific work, however, a high level of concentration is crucial. Sonation offers appropriate sound insulation solutions for all common noise sources in the laboratory.
With the different models, almost any device can be insulated. If a device does not fit into one of the series products, special designs with customer-specific dimensions are also possible.

General information

The temperature and operating data monitoring module APPS (Active Pump Protection System) enables you to perfectly protect your sensitive and important equipment. All important operating data such as temperature, current consumption and the function of the fans are constantly monitored. In case of an error, an optical and acoustic warning is given.

Try before buy
We will gladly supply you with a demonstration unit to try out. If you are not satisfied with the sound protection hood, you can return it without any further obligations.


The insulation material used is oil and water repellent as well as flame retardant according to FMVSS 302 and DIN 75 200.

Ventilation and cooling

Fans trimmed for noise minimization are used to dissipate the pump waste heat. The air ducting inside the box is designed to provide optimum cooling for the pump, yet prevent sound from entering through the air inlet and outlet openings.

Sound insulation

The sound reduction is up to 16dB(A) which corresponds to a reduction of about 80% of the perceived loudness.


To gain access to the pump, e.g. to read the oil level, the front can be removed and reattached with a flick of the wrist using quick-release fasteners.


The sound protection hoods are equipped with pump-specific cover plates. These cover plates allow the sound protection hood to be adapted to the respective pump type. If a different pump is to be insulated, only the cover plate needs to be replaced. Thanks to magnetic locking, the cover plates can be removed quickly without tools.

Flange kits

With some sound protection hoods, it makes sense to extend the pump connections for vacuum and/or exhaust connections. This allows attachments such as oil mist filters or similar to be connected outside the sound protection hood. For this purpose, we offer flange kits in various sizes and lengths.
