SELF-PRIMING ELECTRICAL CENTRIFUGAL PUMPSMODEL ATM GENERAL INFORMATION ATM are self-priming mechanical seal centrifugal pumps in close-coupled execution with open impeller. Ideal for safe installation priming from the top of vessels and/or tanks for transferring acids, solvents and corrosive liquids. The pump has to be completely filled prior to priming; after the first priming, pump design grants that enough liquid remains in the casing for subsequent primings. ATM exclusive design does not require any "Clapet" or non-return valve, that may be subject to wear and deteriorate pump performances. All non metallic wet-end components are injection moulded and/or machined from block material. The ATM, with its low friction coefficient, combined with exclusive balancing system of the external mechanical seal, allows to withstand occasional dry running periods up to one 10 min. On the other hand, the SiC version allows the use of this pumps with particularly aggressive and abrasive liquids. The closed-coupled execution makes the ATM pump very compact, silent and safe.
