Graymills TN37HF 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.

TN 30 Series pumps are equipped with either 1725 RPM (TN 30), or 3450 RPM (TN 30H) motors. The TN 30H, is similar to the TN 30, with the exception of its higher head capabilities. Discharge diameter and maximum viscosity for each pump are listed. These pumps can be ordered as part of a pump and tank systems with 10, 21, 38, 55, and 85 gallon capacities.

TN 30H: Available in ½, 3/4 , 1and 1-1/2 HP, 3450 RMP, 1”NPT vertical discharge. Maximum viscosities are: ½, ¾, 1 HP-300 SSU; 1-1/2 HP-500 SSU.

Special Materials: 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.

Note: Information about the flow curves: 1. TN30H 1-1/2 HP water, 2. TN30H 1-1/2 HP 300 SSU oil, 3. TN30H 1 HP water, 4. TN30H 1 HP 300 SSU oil, 5. TN30H ¾ HP water, 6. TN30H ¾ HP 300 SSU oil, 7.
