Magnetic water pumps. Magnetic driven. Sealless pumps for use on fresh or saltwater aquariums. Low heat exchange . Highly durable design. WMD pumps have American Made Motors. MD pumps have Japanese Made Motors. RLT pumps are for pressure applications. RLXT pumps are for circulation and wet/dry return.
Iwaki Walchem magnetic drive pumps will run longer, quieter and cooler than any traditional mag drive. Extraordinarily high efficiencies make WMD & MD the clear choice in almost every process, recirculation or transfer application.
Unique internal Cooling Circuit Creates a positive, forced cooling path, lubricating bearing surfaces and actively purging gases & heat. Unique double bearing system allows cooling circuit 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. Great pains are taken in the molding/finishing process to eliminate tangential misalignment.
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 Dynamically 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.

Q
Are the 70RT pumps expensive to run 24/7. My husband is freaking out our electric bill will sky rocket. Just wondering? Stacey Peterson. FISH LOVER
I bought this pump because of the great experience I have had with the Iwaki MD100RLT. Great head pressure just does not stop pumping and the water flow is steady as can be. For a pump it is actually not to bad as far as noise. If you are looking for a pump with no noise well good luck on that one. ...Read More
I bought this pump because of the great experience I have had with the Iwaki MD100RLT. Great head pressure just does not stop pumping and the water flow is steady as can be. For a pump it is actually not to bad as far as noise. If you are looking for a pump with no noise well good luck on that one. The Japanese motor is the way I went and am so glad I did. All in all I give both my Iwaki pumps the MD100 RLT and the MD70 RLT with Japanese motors 12 points out of 10, they are that good. Ya see ya pay for what you get. I got top equipment.Hide
