Product Name: Vertical CI Centrifugal Pump & Mtr
Model Number: TNW68F 1
Manufacturer: Graymills Coolant Pump Parts washer
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.

This series is designed to handle higher flow rate requirements and thicker fluids, while maintaining consistent flow. Discharge diameter and maximum viscosity for each pump are listed.

TN 60H: 1HP, 1725 RPM, 1-1/2” NPT vertical discharge. Maximum viscosity: 500 SSU.

TN 70H: 1-1/2HP, 1725 RPM, 2” NPT vertical discharge. Maximum viscosity: 500 SSU.

Note: Information about the flow curves: 1. TN70H water 2. TN70H 300 SSU oil 3. TN60 Water 4. TN60 300 SSU oil
