DuraLobe Series Rotary Lobe Pumps

The DuraLobe® series of bi-wing rotor pumps are offered in both sanitary / hygienic and industrial models. The bi-wing rotor form minimizes slip, allowing relatively high pressures, and also provides large voids for handling soft solids such as cherry pie filling.

Industrial models provide NPT, flanged or rectangular port options for use on chemicals, resins and coatings, water treatment polymers, personal care products and any application that requires the ability to completely clean the pump.

Front loading seals allow easy cleaning and maintenance. Sealing options include single and double mechanical seals, mechanical seals with quench, and single O-ring and double O-ring seals. The O-ring seal pumps are particularly easy for strip cleaning applications, but require reduced operating speeds, as shown in the specification table below.

The sanitary / hygienic models offer a variety of port options, including sanitary clamp, ACME threads and rectangular ports. The fully swept pumping chamber is suitable for Clean-In-Place or strip cleaning. They meet 3A standards for milk and milk products, and are EHEDG certified for in-place cleanability of food processing equipment.
