Flowserve-Innomag-Chemical Process Pumps - ANSI, ISO - Innomag (TB-Mag and U-Mag)

INNOMAG TB-MAG Fluoropolymer-Lined, Magnetic Drive, ISO Or ASME (ANSI) Chemical Process Pump


Compliant with ASME B73.3 or ISO 2858/15783 standards, the INNOMAG TB-MAG pump is engineered to provide low total cost of ownership and exceptional leakage protection in extremely corrosive and environmentally critical applications. The key to its proven performance is its revolutionary dynamic thrust balancing system. This system eliminates the need for thrust bearings and results in highly efficient operation, even in applications containing solids.

Features & Benefits
  • Dynamic Thrust Balancing System eliminates the need for thrust bearings
  • Pump efficiency, reliability and longevity are improved, while operating costs are reduced
  • Pure ETFE Casing Liner is vacuum rated and has a minimum thickness of 3 mm (0.125 in)
  • One-piece ETFE Impeller and Inner Magnet Assembly ensures maximum torque transmission, simplifies maintenance and eliminates balancing
  • Enclosed impeller with unobstructed eye delivers high efficiency and low NPSHR
  • Double-sealed Inner Magnets offer unmatched resistance to corrosive permeation by sheathing the magnets in 316L stainless steel before they are injection  molded into the impeller assembly
  • One-piece Composite Containment Shell consists of aramid and carbon fiber reinforced ETFE for optimal leakage protection and corrosion resistance
  • Composite construction means zero eddy current losses for maximum efficiency
  • Stationary Cantilevered Pump Shaft is oversized to handle all radial loads while maximizing flow and minimizing NPSHR
  • Parts Interchangeability among the available sizes reduces inventory costs and eases maintenance
  • Superior solid handling capabilities allow reliable performance up to 30% solids content of 0,13 mm
