Precision Gear Pump for the Food Industry

Stainless steel precision gear pump for conveying and metering of fluids with medium to low viscosity. Through decades of experience in design and selection of optimal materials, this type of pump suitable for even the toughest of tasks and impresses with its reliability and metering accuracy in the vacuum as well as high-pressure applications. Typical areas of application for this type of pump are to be found in the cosmetic and food industries e.g. for conveying butter, margarine or vegetable oils. Pumps of this type can be supplied with or without heating (hydraulic or electric). The modular construction system for WITTE bearings, gears and shaft seals offers a maximum dimension of flexibility for the user. For better cleaning the pump has different flushing connections. An industry leading special design of this pump helps to minimize dead spots.
