Description
Magnetic water pumps. Magnetic driven. Sealess pumps to be used 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 each process, recirculation or transfer application.Unique internal Cooling CircuitCreates 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 TolerancesPumps may also 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 an incredible feature of all WMD/MD impellers. Great pains are taken within the molding/finishing process to do away with tangential misalignment.Bearings/Thrust surfacesHigh lubricity fluoropolymer bearings minimize mechanical losses typical of conventional mag drive pumps. High purity SiC radial bearings maintain essentially the most aggressive ultrapure chemistries. PTFE front thrust surface aids hydraulic balance and minimizes flashing. Large rear thrust surface guards against axial forces as a result of cavitation or gas entrapment.Drive magnetDynamically 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 matchingOffering more standard motor/pump configurations than other manufacturers offer for tailored pump applications. Premium, high efficiency motors are used all through the line. Totally enclosed, permanent split capacitor motors are compa
