MagDrive Pump

Applications

Close Coupled Design

Arrangement eliminates need to perform pump/motor alignment. Single piece, dual bolt circle adapter accommodates all motor sizes for maximum application flexibility.

Fully Confined O-Ring

Sealed to casing for zero leakage. Acid-resistant Viton standard other materials available.

Casing Drain

Allows complete draining of fluid from pump for system maintenance. Blind flange and gasket ensure leak-free seal for safety.

Rigid Casing Feet

Reduce effect of pipe loads on pump and motor shaft alignment.

Superior Design

Solid Stationary Shaft

Pure sintered silicon carbide construction eliminates shaft delection. Fully supported stationary design maximizes radial bearing life. Straight geometry eliminates stress concentrations and possibility of failure during pump operation.

Bearing Spider

Fully supports Silicon Carbide shaft for maximum shaft rigidity. Protects the end of the Silicon Carbide shaft from damage. Smooth hydraulic flow path into the eye of the impeller, equal to that of a standard ANSI pump. Rounded spider hub and spider supports (flow straighteners) reduce turbulence and pre-rotation for better hydraulic stability.

ANSI Dimensions

Allows easy retrofit of problem ANSI pumps.

Rare Earth Magnets

High strength neodymium iron, provide high torque and hard-start capability without slip. Drive is synchronous.

Installation / Pump Replacement Flexibilty                                                     

The 3298 is available in close-coupled or frame-mounted designs for true installation or pump replacement flexibility.

Since the 3298 meets ANSI dimensional standards, retrofitting mechanically sealed ANSI pumps is easy:

simply replace the old pump with the equivalent close-coupled or frame-mounted ANSI size 3298.

Tefzel Construction For Extreme Corrosion Resistance                                                       

TEFZEL® (ETFE) is inert to most chemicals, and has good abrasion resistance.

TEFZEL® lined casing and containment shell with solid TEFZEL® impeller provide superior corrosion resistance and long life unequalled by alloy pumps.

Enclosed One Piece Impeller / Magnet Assembly                                                       

Enclosed design minimizes axial thrust, extends thrust bearing life. One-piece construction eliminates front shroud failure possible with two-piece impellers.

Neodymium iron magnets are molded in place, reducing the chance of permeation.

Design Features for Extended Pump Life

Casing with TEFZEL^® Lining

One-piece solid ductile iron casing with Tefzel® lining. Generous lining thickness of 1/8 inch (3 mm). Rotolining process assures integrity of lining. Rugged foot mounted design provides maximum resistance to and distortion from pipe loads. Flange loads are the same as metal ANSI pumps. Casing drain allows complete evacuation of pump fluid.

Radial and Thrust Bearings                                                       

Multiple materials available to best suit your pumping application: Carbon, pure sintered

Silicon-Carbide or Dryguard™.

All rotating bearings are designed with

flow grooves to help circulate fluid over

the bearings and to help flush solids away.

Dryguard™ option keeps your pump

running when temporary dry run conditions exist.

Forgiving hydraulic design and positive axial

thrust allow the pump to get through dry

run conditions without damage to other components.

Containment Shell                                                       

TEFZEL® lining with glass reinforced vinylester backing. Burst pressure greater than 500 psig. Fully confined O-ring seals containment shell to casing.

Non-metallic construction provides efficiencies same or better than sealed ANSI pumps; 30% higher efficiencies than metal sealless pumps.

Non-metallic construction eliminates magnet losses and heat  generation. Heat sensitive liquids are easily pumped.

Self Priming

In-Line Design for Cost Savings

Dry Run Capability

Standard Dryguard Silicon

Carbide Bearings

Provide the corrosion resistance and

durability of silicon carbide with short

term dry run capability without the

catastrophic failuremodes of standard

silicon carbide in a dry run situation.

Solids Handling
Standard large internal clearances allow

the passage of solids up to 0.06 inches

with a maximum concentration of 2%.

With the optional clean external injection

flush, the 3299 can handle solids up to

0.080 inches with a concentration near 10%.

PFA Construction for Universal Corrosion Resistance to 360°F (182°C)

Virgin Teflon® (PFA) is virtually inert to all chemicals and has good abrasion resistance. PFA lined casing, bearing carrier, containment shell, and one-piece impeller/shaft assembly provide superior corrosion resistance and long life, unequalled by alloy pumps.

Designed for Safe Operation

Dual Containment Shell

PTFE lining with carbon fiber reinforced plastic (CFRP)
shell. Non-metallic construction provides efficiencies the same or better than sealed ANSI pumps; 30% higher efficiencies than metal sealless pumps.

Non-metallic construction eliminates magnet losses and heat generation. CFRP shell provides rigid support for the liner and acts as a secondary method of

containment should the primary liner fail.

Integral Shaft and Impeller

Large 316 stainless steel core improves impeller
mechanical strength. Integral PFA lined 316 stainless shaft
and impeller optimizes corrosion resistance, strength and
durability of the stainless steel shaft.

Zero Leakage                                                       

The 3298 is sealless and environmentally safe.
No mechanical seal assures zero leakage on moderate to severe corrosives, hazardous liquids.
A great solution to pumps with mechanical
seal problems.
