HR49 1/8hp. Vertical CI Pump & Mtr.

Product Name:

Vertical CI Centrifugal Pump & Mtr

HR49B 1/8


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.

HR Series pumps are widely used for circulating thin liquids, and abrasives. Impellers are open type. No bearings, packings, or seals below liquid level. HR Series pumps can be purchased as part of a pump and tank system with 5, 6, or 10 gallon capacities. Viscosities and discharge diameter vary with pump model and are listed below.

HR 15 Specifications: 1/15 HP, 3000 RPM, 3/8” O.D., slip-on vertical discharge. Maximum viscosity: 100 SSU.

HR 35 Specifications: 1/25 HP, 1500 RPM, ½” NPT horizontal discharge. Maximum viscosity: 150 SSU.

HR 45 Specifications: 1/8 HP, 1725 RPM, ½” NPT horizontal discharge. Maximum viscosity: 500 SSU. HR 45 pump is available as an Agitator style pump (See HRAG model).
