Proven to be reliable, safe, compact and efficient, ANSIMAG sealless magnetic drive ETFE lined pumps provide a number of operational benefits:

  • Magnetic Drive: this patented technology hermetically seals the inner magnets, isolating them from process fluid, which maintains magnet integrity for the life of the unit.
  • Close Coupled Design: leverages off-the-shelf NEMA C Face or IEC-B5 Flange motors, and still provides a small footprint, quiet operation and low maintenance.
  • Corrosion Protection: Powder Coat exterior is more durable and chemically resistant than Epoxy based paints.
  • Easy Service:  ANSIMAG Back Pull Out design enables the Drive End to be serviced without breaking into the Wet End.
  • Sealless Containment:  Lined Kevlar Fiber/Epoxy construction provides unsurpassed pressure handling capability.
  • Radial Thrust:  All ANSIMAG pumps feature a fully-supported shaft to eliminate radial shaft deflection at low flow operating conditions.
  • Zero Leakage:  A single, fully-contained O-ring eliminates possible leakage.
  • Chemically Resistant Lining:  Carbon Fiber reinforced ETFE is resistant to most chemicals.
  • Durable Construction: Ductile iron exterior is designed for heavy-duty chemical applications.
  • Axial Thrust Washers: increase the allowable operating range over thrust balanced methods. This increases the pump’s reliability through a positive thrust surface that is unaffected by cavitation, solids or transient suction conditions.
  • Simple Sealless Design: Consisting of only 9 wetted parts, ANSIMAG pumps can be quickly and easily repaired in the field.  Routine maintenance or repairs can be performed without the need for special tools or training.
  • Replaceable Impeller:  a single-piece replaceable impeller is attached to the inner magnet drive via ANSIMAG’s patented tongue & groove system.  The separation provides a cost effective approach to warehouse spare parts management and re-rating operations.
  • Run-for-Life Bushing:  Silicon Carbide bushings provide near maintenance-free operation for the life of the pump.
  • Fully-Encapsulated Inner Drive: provides unsurpassed resistance to chemical attack.

Installed in the Motor Control Center (MCC), a power monitor measures the power required to operate the pump.  By setting High and Low trip points, the power monitor is the perfect solution for protecting your pump from:

  • Dry running
  • Low flow operation
  • High flow operation
  • Severe cavitation
  • Magnet de-coupling
Motor Control Center


Long coupled configurations conform to ANSI B73.3 dimensions for easy replacement of mechanically sealed pumps (utilizing same baseplate, coupling, guard and motor).


ASME B73.3 compliant back-up to control or contain leakage in the event primary pressure containment is breached.

Solids Handling

With its generous internal clearances, ANISMAG pumps are designed to handle liquids with solids up to 20%+ w/w, 1/8 inch diameter.

Unlike competitive designs, ANSIMAG pumps do not rely on close fitting internally wetted Silicon Carbide wear rings (held in place with non-metallic snap rings) that can trap solids or lock-up the pump.

Frequently Handled Solids:

  • Inorganic Salts
  • Fine Sand
  • Caustic Precipitates
  • TiO2(Paints & Coatings)
  • Slag (Steel Pickeling)
  • Carbon Black
Solids Handling


Solid state device for detecting liquid in the event of a leak in the primary containment shell.


Fitting an ANSIMAG pump with Carbon radial bushings reduces the coefficient of friction with the pump shaft extending the life of the pump during process upset or dry run operating conditions.


Baseplates pre-engineered, chemically resistant polymer concrete bases provide a superior foundation to channel steel alternatives.
