*Seperate Power Cord is required for use.Magnetic water pumps. Magnetic driven. Sealess pumps for use on fresh or saltwater aquariums. Low heat exchange and quiet in operation. 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.
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.
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.
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.
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.
Flow Rate @ 4` Head: 540 GPH
Max Head ft: 8.2
In the unlikely event there are any problems with Iwaki water pumps or warranty work is needed at some point, please contact Iwaki directly at 508.429.1440 for an RGA. Do NOT send a pump back to Iwaki without an RGA number. Please contact us for any assistance you may need in this unlikely situation.

Yes, I would recommend this.
The best ever pump
Pros: Best pump tested over 20 years.
Cons: You need to place it on some antivibration material just to prevent transmitt of small vibrations as every pump have.
In 1997 I purchased 2 of this pumps in Hong Kong acquarium shop and until today with regular cleaning over 20 years this pump works like new. Its hot on work but this is normal. Not even small sign of worn. I clean and lubricate axles inside once in few years. Rotor is simple to remove and clean from debris. Trust me the best Japanese pump in the world. To show you see my controller drawings and date with 2 Iwaki pumps 1997 in Italy.
