The Amarex KRT range of submersible motor pumps are available with drive ratings of 10 to 30 kW and are suitable for vertical or horizontal dry installation. Since the pump motors remain fully operational when not submerged, the pump sets can also be used in pump sumps when water levels have dropped. Thanks to IP 68 enclosures, the pumps also offer trouble-free continuous operation when flooded. The pump sets meet all explosion protection requirements set out in the Atex, FM and CSA standards.
The motor is cooled via a closed circuit which avoids contact between the circulating water-glycol mixture and the fluid handled. This also rules out any risk of contaminants in the fluid handled impairing the cooling of the motor. The cooling liquid is circulated by a special impeller which the pump’s design engineers have integrated into the cartridge seal.
The pumps are able to transport fluids with a temperature of up to 40 and operate in environments with a temperature of up to 55 °C.
