Food pumps PURO

Gear pumps for food applications

Easy to clean and individually designed

Stainless steel gear pumps to transport and dose low to middle viscous media.
Through decades of construction experience and optimal material selections, this pump type is suitable for even the most difficult of tasks and maintains its reliability and dosing accuracy in vacuum and high pressure applications.

Typical areas of application for this pump type can be found in the chemicals, cosmetics and food industries to transport, for example, margarine or vegetable oils. This pump type can be heated (hydraulically or electrically) as well as unheated. The modular WITTE construction kit for friction bearings, gears and axial shaft seals offer the highest degree of flexibility for users. The pump has different rinse connections for better cleaning. A design with little dead space was considered during the construction; a completely dead space free  design is not possible due to the construction.
