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

Characteristics
The main components are made of GG20 cast iron. The mechanical and lip seals ensure proper operation of the product. A version with a double mechanical seal in the oil chamber is available.
Advantages of the AM-AT series dirty-water pumps
Unlike the BIC series, AM-AT series pumps have a threaded side outlet. The manufacturer has provided ATEX certification for the pumps and the necessary equipment, such as a special cable with a gland and an ATEX control panel (available to order). The AM-AT series has only one passage size, restricted by a screen with 20x10 mm mesh openings. The pumps are fully compatible with EASY E3.1 and EASY E3.2 coupling feet and discharge pipelines from DN32 upward.
Open, two-blade impellers handle even heavily sand-laden wastewater exceptionally well. The thick impeller walls are suitable for many years of operation in raw domestic wastewater.
Control
AM-AT-Ex 50/2/110 dirty-water pumps are offered without a built-in float. When operating in an explosive atmosphere, the EX GEX - ATEX float switch EX GEX - ATEX float in an explosion-proof version must be used. It may require protection in the control system (not supplied by Dambat) in the form of an EMS protective relay/barrier EMS - EXI / 2 relay (Ex protective barrier) for ATEX floats
Possible applications
With a suitable hose connection (an elbow ending in a plain end), the pump becomes a lightweight portable pump for drainage and handling liquids with a high content of solids (gravel, sand, waste). AM-AT pumps are used for drainage in mines (especially EX applications), transferring process water at wastewater treatment plants, and in demanding industrial conditions. The pumps have stable feet extending from the pump body, providing sufficient clearance beneath the body for water intake.
Like every DRENO wastewater pump, the AM-AT comes standard with a 10-meter power cable.
