Features:

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 acids, caustics, solvents, bleaches and waterlike fluids.
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.
A built-in thermal protector
Automatic shutdown if pump exceeds temperature or electrical limits.
Lightweight construction and easy handling for emergency situations
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.
Extremely user friendly design
Pump inspection, maintenance and parts replacement are quick and simple. Silicon carbide and engineered ceramics and Rulon® make this a very reliable pump to stand up under harsh conditions.
 
 
 
 
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 two Rulon® bushings. If abrasives are present an optional ceramic bushing is available.
All motors for new GW series pumps are heat-resistant up to 167 ?F (75 ?C).
