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).
The HR 35 and 45 pumps are available with a nickel-plated body and volute and a stainless steel shaft for special applications.
