Iwaki Magnetic Drive Pumps will run longer, quieter and cooler then any traditial magnetic drive pump. Iwaki MD series pumps have a japanese moter that sets the standard for aquarium pump. Iwaki WMD series pumps are also available inwith the more economical domstic motor.

RLT pumps are for pressure applications. RLXT pumps are for circulation and wet/dry return.

Uniqu e internal Cooling
Creates a cooling path lubricating bearing surfaces and actively purging heat. Unique double bearing system allows cooling liquid to continually "wash" front and rear radial bearings extending bearing life.

Precision Tolerances
Pumps can be supplied with alumina ceramic or SiC spindles bored turned and highly polished. This precision machined spindle forms the center of the driven magnet. Substantially reduced hydraulic noise is a major feature of all WMD/MD impellers.

Bearings/Thrust surfaces
High lubricity fluoropolymer bearings minimize mechanical losses typical of conventional mag drive pumps. High purity SiC radial bearings handle the most aggressive ultrapure chemistries. PTFE front thrust surface aids hydraulic balance and minimizes flashing. Large rear thrust surface guards against axial forces caused by cavitation or gas entrapment.

Drive magnet
Balanced barium ferrite drive magnets provide best magnet torque. Die cast magnet carrier creates a flywheel effect which adds to the magnet safety factor.

Motor matching
Offering more standard motor/pump configurations than other manufacturers offer for tailored pump applications. Premium high efficiency motors are used throughout the line. Totally enclosed permanent split capacitor motors are compact cool and economical. Tolerance to voltage variation without overheating and 50/60 Hz operation allow the product to be used in a worldwide market.
