Vacuum connection (inlet)

Inlet: Small flange connection KF DN 25 with clamping

ring and centring ring.

Connect the vacuum line (e.g., metal hose (stainless steel)

KF DN 25) at the inlet of the pump.

• Reduce the transmission of vibration. Pre-

vent mechanical load due to rigid pipelines.

Insert elastic hoses or flexible elements

as couplings between the pump and rigid

pipes.

Note: Flexible elements will compress or

flatten when evacuated if not designed for

use under vacuum.

• Hose connections at the pump inlet must al-

ways be gas tight.

Use a suitable adapter to connect a vacuum

inlet

Use connecting hoses with large diameter and

keep them as short as possible to avoid flow

losses. Locate the pump as closely as possi-

ble to the application.

Secure hose connections at the pump ap-

propriately, e.g., with hose clamps, to protect

against accidental detachment.
