The AM-AT series is designed for pumping clean water or lightly polluted wastewater. Its high hydraulic efficiency makes it particularly suitable for pumping rainwater, surface water, groundwater, water from pools and waterways.
The pumps can be used in all hazardous areas, in accordance with certificate CE0477 EPT 17 ATEX 2701 X, Ex II 2G [Ex db IIB T4 Gb, Ex h IIB T4 Gb, 0°≤Ta≤40° available on request.

Specifications
The main components are made of GG20 cast iron. Mechanical and lip seals ensure the product operates correctly. The version is available with a double mechanical seal in the oil chamber.
Advantages of AM-AT series dirty water pumps
Unlike the BIC series, AM-AT series pumps have a threaded side outlet. The manufacturer has ensured that the pumps are ATEX-certified and provided the necessary equipment, such as a special cable with a cable gland and an ATEX control panel (available to order). The AM-AT series has only one passage size, restricted by a mesh filter with 20x10 mm openings. The pumps work well with EASY E3.1 and EASY E3.2 coupling feet, as well as discharge pipes from DN32 and up.
Open two-blade impellers perform excellently even with wastewater containing a lot of sand. The impeller’s thick walls ensure years of operation in raw domestic wastewater.
Control
AM-AT-Ex 50/2/110 dirty-water pumps are offered without a built-in float switch. W explosion-hazard environments, use an EX GEX - ATEX float switch EX GEX - ATEX Float Switch in an explosion-proof version. It may require protection in the control system (not supplied by Dambat) in the form of an EMS relay/protective barrier EMS - EXI / 2 Relay (Ex Protective Barrier) for ATEX Float Switches
Possible applications
With the appropriate hose fitting (an elbow with a plain end), this is a lightweight, portable pump for drainage and for handling liquids with a high solids content (gravel, sand, debris). AM-AT pumps are used for drainage in mines (especially EX mines), transferring process water at wastewater treatment plants, and in harsh industrial conditions. The pumps have stable feet extending from the pump body, providing adequate clearance beneath it for water intake.
Like every DRENO sewage pump, the AM-AT comes standard with a 10-meter power cable.
