Heavy Duty Industrial Coolant Pump

  • Cast Iron Casing and Column
  • 3/4˝ to 1-1/2˝ NPT Discharge Port
  • Includes Universal Mounting Bracket
  • Dual Volute Design Reduces Radial Load on Motor – NO BOTTOM BEARING!
  • Maximum Temperature 200° F
  • Maximum Flow 67 GPM
  • Maximum Head 32 Ft.
  • Self-Cleaning, Semi-Open Stainless Steel Impeller
  • Available with Single or Three Phase 56C Motor
  • 1/8 to 3/4 HP Totally Enclosed Fan Cooled (TEFC) Motor, 1725 RPM

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 included with these pumps (see below).

AMT Mounting Brackets (Included):
Models 4410-90 & 4420-90 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.

Pump Dimensional & Specification Data

† Immersion-type pumps require no bearings, seals, or packing, ideally suiting them for pumping liquids containing fine contaminants. For circulation of coolant and spraying of cutting oil in all machines, including grinders and applications with higher temperatures.

*Suction-type pumps must be mounted above the liquid level as well as other remote locations, featuring a 2 ft. maximum suction lift. For circulating coolant, liquids with large amounts of foreign matter and spraying cutting oil in all types of machines, except grinders.

Maximum Recommended Viscosity: 500 SSU

Pumps feature Totally Enclosed motors with sealed, permanently lubricated bearing for protection from dirt,moisture and soil.
Available in:
Single (1) 115/230 VAC 60 Hz
Three (3) 230/460 VAC 50/60 Hz
