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.

Comments: I have used Little Giant in the past to run my canister filter and was happy with them. This Iwaki seems to be a great alternative, its quiet, provides good power and runs cool.

Comments: This is the second one I have owned for a 1000g pond. The first one lasted 10 years of non-stop operation through all seasons . . . and it quit because it ran dry when the pond filter became clogged. A very impressive unit!

Good not Great

Experience Level: Beginner


Comments: I'm new to a using a sump so I didn't really know what pump to get, so I read the reviews and seen the specs and I have to say it's too powerful for my 55 gal aquarium. It's a 3/4" inflow/ outflow pump that I use with my 1" overflow drain which is gravity driven. When I first put my sump together it drain my 20 gal sump in about 45 seconds and your heard this god awful slurping sound because my overflow drain can't keep up. So I solved my problem by installing a ball valve after my pump going to my tank to regulate my sump water level. I would of rated this pump with more stars but my wife was irate because the NOISE that comes from this pump is extremely LOUD! Eventhough I have my pump mounted on my stand with rubber washers with my doors closed it still sounds like my wife is vacuuming in the other room all day. Hope this helps.

Comments: I purchased this pump over 10 yrs. ago and it is still running great. I have never had to do anything to it. I have a 125 Cichlid tank, with a wet/dry filter system! The pump made some noise sitting on the base of the cabinet, so I hung it in the air with a piece of wire,eliminating my noise problem.It"s a GREAT PUMP !!
