Recently launched by 3M Pumps and now available from this firm, the T MAG-M pump (photo) is a horizontal, sealless peripheral pump with a permanent-magnet drive system and no mechanical seals. Features include a high-power, synchronous magnetic coupling, which can be operated at liquid temperatures up to 350°C (without external cooling); a hydraulic design with a self-balancing impeller, which improves wear ring life; and a sealing system with flat gaskets, which prevents leakage to the atmosphere. The real shell is made in a single piece, without welding, and its ellipsoidal profile helps it to withstand higher pressure than traditional designs. The pumps deliver flows up to 12,000 L/h at pressures up to 16 bar. — Pump Engineering Ltd., Littlehampton, U.K.
