Mag-drive pumps for challenging environments

| By Chemical Engineering

This company’s magnetic-drive pumps now exceed driving power of 515 kW, with flowrates of 3,500 m3/h, delivery heads of 160 m and system pressures from PN 16 to 400. They can operate at temperatures of 450°C without external cooling and can handle viscosities of over 3,000 cP-s. An API 685 pump (photo) includes such features as: a double-wall isolation shell to provide secondary containment; protecting rub rings to avoid damage to the isolation shell coming from the rotating inner and outer magnetic ring; a 300-lb centerline supported casing; confined control compression gaskets; renewable wear rings; anti-friction bearings designed for 50,000 h; and non-sparking labyrinth rings.
