Stancor MK ANSI Centrifugal Pumps

Manufactured from solid Kynar or PTFE

Stancor MK Non-Metallic ANSI Centrifugal PumpThe ultimate in sealless pumping technology, Stancor MK series Mag-Drive ANSI Centrifugal pumps are made from solid kynar.  These are ideal for applications that require durability and performance on dirty, difficult fluids.  There are no liners to separate or collapse, no permeation and the impellers can be trimmed to your application.

These ANSI pump conform to ANSI B73.1 specifications and would be an excellent cost saving alternative to expensive alloy pumps.  Stancor pumps eliminate the wicking associated with many fiberglass pumps and complications of lined pumps.

Dual Volute: The MK4 and MK12 have dual volute casing design which lowers radial bearing loads to provide longer life and allows continuous operation anywhere between 1 M3/H to full flow.
Magnetic Coupling:

Samarium cobalt magnets provide high torque throughout the temperature operating range -20°F to 250°F (-28°C to 121°C). One magnet coupling assembly fits all pumps. This lowers cost and simplifies inventory. The inner magnet is fully Kynar (PVDF) encapsulated – no weld seams no potential leakage.

Enclosed Impeller and Magnet:

The impeller and inner magnet is a two-piece, enclosed assembly. When worn, the impeller can be replaced without replacing the magnetic drive which substantially reduces repair cost. Impellers can be trimmed in the field.

Pump Casing:

The pump casing is constructed of 1/4” (6.35 mm) minimum wall thickness, carbon fiber filled Kynar (PVDF). This is more reliable, without permeation problems commonly found in lined metal casings.

Case and Flange Supports:

Chemical resistant glass filled vinyl ester composite and glass-filled nylon provides superior performance to painted metal.

Unique Design:

Patented thrust balancing system eliminates axial loads to dramatically reduce wear and heat generated from friction. Inner magnet and impeller assembly float axially.

Heat Dissipation:

Non-metallic Kynar and carbon fiber-braid containment can superior to a metal can design for eliminating heat generated from eddy currents created by alternating flux lines.

Easy Assembly: Assembly of pump and motor driver is fast and easy due to the motor shaft in full view and low pump weight.
Chemical Compatibility:

Kynar (PVDF), Silicon Carbide and o-rings (Viton, EPDM, or Simriz) are the only materials in contact with the pumpage.

Rugged Construction:

Fine grain “Alfa” silicon carbide for higher strength and more fracture resistance. High grade carbon or glass filled non-metallic components for high strength and chemical resistance. 300 Series stainless steel hardware.

Efficient Installation: Back pullout design per ANSI B73.1, does not disturb piping
