DesignRiotec:Maintenance-free wet rotor pump (glandless), flangedor screw-ended, with integrated frequency inverter for continu-ously variable differential pressure control.I.R. (infrared) interface for remote control.LON bus interface can be retrofitted.Riotec Z : Riotec twin pump for stand-by operation (integratedswing check valve) or, on option, additional starting in case ofpeak load (parallel operation).
Control modes:-- ∆p-c for constant differential pressure in the pump-- ∆p-v for variable differential pressure in the pump-- ∆p-T for temperature-governed differential pressure in the
pump

Pipe ConnectionFlanged pumps fitted with an adapter flange (oval bolt hole pat-tern) can be connected to PN 6 and PN 16 mating flanges toDIN or DIN EN up to nominal diameters of DN 65. Adapterflanges of this type cannot be connected with other adapterflanges. Use bolts of property class 4.6 or higher for the flangeconnections. Thewashers included in the scope of supplymustbe fitted between the bolt / nut head and the adapter (oval bolthole) flange.
