Explosion-proof pumps
The 2-pole ATH series is used for pumping and transferring large quantities of clean water or light wastewater at high pressure. Applications: water treatment plants, industrial pipelines, airports, hospitals, civil applications, and agricultural irrigation.
The pumps can be used in all potentially explosive atmospheres, 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.
Characteristics
All major components are made of GG25 cast iron. Two separate mechanical seals (motor side in the oil chamber, impeller side in contact with the liquid), together with high-quality components, ensure excellent performance and product reliability.
Advantages of the ATH high-head pump
ATH pumps can pump light wastewater (greywater) or dirty water while generating high head, thanks to two-channel impellers with a free passage of 30–45 mm. Within this size range, most domestic wastewater can pass through freely (the exception is fibrous debris, which should not be present in household wastewater). Thanks to the limited channel size, the pumps maintain high efficiency while offering a very versatile range of applications: wastewater treatment plants, supplying large quantities of water from wells, crop irrigation, and livestock farming.
Installation of ATH wastewater pumps
ATH pumps do not require special installation systems; they are typically installed on automatic couplings (coupling feet): type A (horizontal), type B or DUTY. The pumps are designed so that their weight (the pressure exerted on the connection) counterbalances the repulsive force generated by the pump; therefore, the pump does not tilt and there is no pressure loss. The pumps can operate across their entire performance range, although the operating point closest to the point of maximum efficiency is naturally recommended.
