The minimum flow velocity in the pressure piping must be 0.7 m/s according to EN 12056.
This data is represented in the performance curve as a limit of application.
Single unit 1½" with GR 40: sump area min. 40x60 cm
Single unit 1½" without GR: sump area min. 40x40 cm
Duplex unit 1½" with GR 40: sump area min. 60x60 cm
Duplex unit 1½" without GR: sump area min. 40x60 cm
In case of installation beneath the backpressure level the pressure tube must be taken in a loop over the local backup level acc. to EN 12056. Besides, it must be secured with an EN 12050-4-proofed swing-type check valve. Additionally we recommend an alarm system.
In accordance with EN 12056-4 section 5.1, it has a built-in automatic spare pump or a double attachment included, which ensures that sewage drainage is not interrupted.
