TN50 Vertical CI Coolant Pump & Mtr.

Product Name:

Vertical CI Centrifugal Pump & Mtr

Model Number:

TN53F 3/4


Graymills pumps are typically found on OEM machine tool equipment and are thus well suited for replacement or retrofit machine tool pumping applications. These pumps can also be used on other industrial applications requiring a vertical cast iron or stainless pump.

TN Series pumps are designed to cover a wide range of pumping applications. They can handle thin and heavy liquids containing abrasives and bits of solids, while maintaining consistent and dependable flow. Except for the 24” and 36” models, pumps are designed so that there are no bearings or seals in the liquid, making them virtually maintenance-free. All TN series pumps are available with nickel plating, baked epoxy, Teflon or nylon coatings, and stainless steel shafts for extra corrosion and abrasion resistance.

The TN 50 Series generates approximately 30% more volume than TN 40 Series pumps. Discharge diameter and maximum viscosity for each pump are listed.

TN 50 Specifications: 3HP, 1725 RPM, 1-1/4” NPT vertical discharge. Maximum viscosity: 500 SSU.

TN 50H: 3HP, 3450 RPM, 1-1/2” NPT vertical discharge. Maximum viscosity: 500 SSU.

TN 50HH: The TN 50HH has the same specifications as the TN 50H, but with a larger diameter impeller to produce higher pressure.
