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
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: ¾ HP, 1725 RPM,
1-1/4” NPT vertical discharge. Maximum viscosity: 500
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.
