Iwaki MD Water Pump (Japanese Motor) Information



Part #: MD-20RT-115NL

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.

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.

Iwaki MD30 Product Review by BILL MARCIANTI (Posted on 2/28/14)
Rating
Excellent!

Comments: Great pump, incredibly quiet and plenty strong to run my ETSS Skimmer which was recommended to run with the MD40. Only draw back is it does get very hot, but I'll take the heat over noise any day. I also purchased the MDX40 which works great but because of the fan it is a little noisy!! All in all you can't beat these pumps, well worth the money!!

FORGET THE REST Product Review by KURT KEENER (Posted on 2/26/14)

Excellent!

Comments: THE JAPANESE PUMPS ARE SECOND TO NONE. I have had 3 55rlt running 24-7 for over 13 years and besides the once a year acid bath and a dust blowout, flawless. If you need the flow and you think this is not just a passing hobby. DO NOT THINK ABOUT THE PRICE there Worth every penny. just buy them.

Too loud Product Review by R.Mac (Posted on 2/26/14)

Excellent!

Comments: Pump is too loud. I would go with an internal pump next time to reduce noise and add a chiller if I had too. This pump adds little to no heat to the system and puts out excellent circulation. OK pump.
