AT

Electrically driven submersible motor pumps for liquid manure, in stationary (AT) and mobile (ATF, GTF) versions. The stationary AT range (AT 44 F to AT 304 S) covers 3.0 to 22.0 kW and flows of 2,300 to 6,700 l/min (up to 402 m³/h); the mobile ATF (5.5 to 7.5 kW, 3,800 to 4,800 l/min) and GTF (7.5 to 15 kW, 4,200 to 5,700 l/min) versions are listed on the same page. Examples: AT 74 S 5.5 kW with 4,200 l/min at 11 m, AT 104 S 7.5 kW with 4,800 l/min at 13 m and AT 154 S 11 kW with 5,100 l/min at 18 m. Overloadable motors on 400 V, 50 Hz three-phase supply, clogging-resistant free-flow, open or screw blade impellers (hardened tungsten carbide steel on the S version), a specially shaped inlet for liquid manure with bedding material, straw and feed residues, sealing sensors, built-in thermal contacts, transport lugs and a standard 8 m cable. Used for stirring and emptying open and closed lagoons and tanks with foil or concrete roofs and steel tanks at agricultural holdings and biogas plants.
