Dorr-Oliver Centrifugal Pumps

Handle corrosive and abrasive solids with our heavy-duty centrifugal pumps

Dorr-Oliver Centrifugal Pump
  • Olivite Pumps
  • Olivite OB-1 Pumps
  • Olivite ANSI Pumps
Olivite™ centrifugal pumps are constructed of heavy metal, and are lined with 1/4-inch highly corrosion and abrasion-resistant liner materials (Kynar® impeller or Hypalon® liner). Olivite pumps are available in direct drive or V-belt design. With the ability to handle corrosive and abrasive solids, Olivite pumps are the superior solution for handling acids, alkalies and slurries.

Benefits

The Olivite OB-1 pump can be operated under severe high temperature and high pressure conditions due to its proven design of lightweight Kynar impeller reinforced with fine glass or carbon. Can reach maximum temperatures of 250°F using Kynar lining or 215°F with Hypalon liner, unless restricted by the compound being pumped. The heavy-duty construction ensures that shape is retained, while its low weight and highly efficient vane geometry reduces shaft deflection, resulting in longer bearing life and improved pump performance.

Applications

The pump is commonly used with acid, alkalies, and chlorine compounds at maximum pressure of 180 psi. Olivite OB-1 Pumps are available in three sizes.

Benefits

These pumps are designed to ANSI specifications with back pull out, and include solid Kynar impellers for pumping applications involving nearly all corrosive solutions, hot as well as cold. Our ANSI Pump is constructed with vulcanized lining material (Kynar or Hypalon) mechanically locked into the ductile iron metal casing so it won’t shake loose and enables longer service life. The impeller design is optimized for greater efficiency and very low Net Positive Suction Head (NPSH) and can be adjusted externally, requiring no seal readjustment or special tools, thus simplifying operation.

Applications

Primarily used for pumping filtrates, the Type L pump’s stainless steel construction is especially suited to food and chemical processing applications. Parts are interchangeable on 1-1/2” and 2” models minimizing parts stocking. Mechanical seals or packed boxes are available for greater flexibility. Choose from direct connected or optional V-belt drive assemblies
