AMT Pumps - 4421-95 & 4422-95 & 4430-95 & 4431-95 - Heavy Duty Industrial Coolant Pumps
1 Year Warranty

The AMT Heavy Duty Industrial Coolant pump has been designed for a broad range of Industrial/Commercial coolant and recirculating applications. All models with extended shafts are fitted with aligning coupling between motor and shaft with no bottom bearing. A Universal mounting bracket system is included with these pumps to simplify the pump installation/removal process and expand the application range for each pump in the line.

AMT Coolant pumps are reliable and economical. For use with non-flammable liquids. Compatible with pump component materials.

Optional AMT mounting brackets are designed to simplify the pump installation/removal process and expand 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.

Stop! Required before ordering:

Please check the chemical resistance chart to determine if your pump is fit for your purpose, application and that the pump and seals are compatible for your use.
Warranty is subject to the proper selection of material and seals of the product you are pumping.
