Pump Engineering
The 3M magnetically driven centrifugal pumps (photo) have no glands, seals or valves and therefore provide leak-free operation in heavy-duty operation, such as pumping heat transfer oils and liquefied gases, and at temperatures ranging from –150 to 450°C. Other applications include transferring alkalis, hydrocarbons, toxic and explosive chemicals in the chemical industries. In the food and beverage sectors, the pumps are suitable for handling clean-in-place (CIP) chemicals, such as sodium hydroxide, nitric acid and hydrogen peroxide, and for pumping water-treatment chemicals. — Pump Engineering Ltd., Littlehampton, U.K.
