Sealless Magnet Driven Submersible

World's first entirely corrosion resistant non-metallic magnetic drive sealless submersible pump

Constructed of Polypropylene (carbon fiber reinforced) with a PVC encased power cord. Perfect for most low viscosity acids, caustics, bleaches and waterlike fluids compatible with polypropylene.

Magnetic "NO SEAL" coupling

Ferrite magnets and an engineered ceramics eliminate the most common reason for pump failures. Air filled motor and liquid chambers are completely separate. No oil in motor to leak into pumpage - Cannot add air to liquid  - no contamination.

Light in weight construction and easy handling for emergency situations - 
Small 10" x 15" footprint

Pump weight is 57.3lbs. (26 kg) for the YD-502/512GW. With an easy grip handle, it can be transported quickly in emergency situations. Preparation for operation is as easy as placing it in the tank to be used. 2" NPT discharge on all models.  

Powerful Motor with a built-in thermal protector

The 1 1/2 HP motor with thermal over-load protector Automatic shutdown if pump exceeds temperature or electrical limits. Supplied with 16 foot PVC encased power cord - 32 foot overall length - 230V or 460V -3 phase.
2" Discharge for flow rates to 80 GPM

Standard impeller is suitable for solution specific gravity to 1.1.  Impeller is trimmed to handle specific gravities to 1.50.  High flow impellers (Model 502) or higher pressure impellers (Model 512).  See below for performance curves.

High Temperature Limits

Motor suitable for liquid up to  167oF with High Temperature cord.

Extremely user friendly design

Pump inspection, maintenance and parts replacement are quick and simple. Silicon carbide and engineered ceramics and RulonR make this a very reliable pump to stand up under harsh conditions.

Overview:

  • Material: CFR PP 
  • World's first entirely corrosion resistant magnetic drive submersible pump usable in strong acids and strong alkalis 
  • CE-approved 
  • Adoption of a magnetic coupling to keep liquid from contacting the motor 
  • A built-in thermal protector 
  • Constructed for easy part replacement and maintenance
Principles of the Magnetic Drive Submersible:

Impeller and motor coupling is accomplished by the use of ferrite magnets encapsulated within the polypropylene impeller and attached to the motor drive. Pumped fluid is kept from contacting the motor by an engineered ceramic plate, capable of handling a wide range of liquids. Because the plate is non-metallic, no heat is added due to eddy current losses. Under normal operation the impeller does not come in contact with the ceramic plate, but rather thrusts forward to the suction side, running on the front bushing.

Solids slurries and air are centrifugally forced to the outer casing and ejected through the discharge pipe.
Normal maintenance requires easy replacement of 2 Rulon™ (ETFE) bushings. If abrasives are present an optional ceramic bushing is available.  Stationary spindle is SilCarbide.

All motors for new GW series pumps are heat-resistant up to 167°F (75 °C).  High temperature power cord used for solutions over 130°F.
