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. Ideal for coolant and lubrication systems, parts cleaners.
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 24â€ and 36â€
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.
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 30 Specifications: 1/8, ¼ HP, 1725 RPM,
