AMT 4422-X5
The AMT Heavy Duty Industrial Coolant pump has been designed for a broad range of Industrial/Commercial coolant and recirculating applications. Back vanes on the impellers of models 4421-95 through 4443-95 balance pressure and thereby eliminate the need for mechanical seals. All models with extended shafts are fitted with aligning coupling between motor and shaft. Dual volute construction of models 4421-95 through 4443-95 eliminates radial thrust and therefore the need for bottom bearings. A Universal mounting bracket system is available for these pumps (see below)**

A Cast Iron Mounting Bracket is available for this model. The mounting brackets are designed to simplify the pump installation/removal process andexpand the application range for each pump in the line. With the bracket system, it is no longer necessary to disassemble motor from pump end for installation and removal. Simply unfasten the brackets from the tank cover and insert or remove the complete pump. The bracket system also controls the immersion depth of each pump in the line by clamping to the pump column at the most desirable position (click here). See Curve "C"
