DC Motor Options

Iwaki America offers 12, 24 and 48 volt DC motors, brushed or brushless, for all of our WMD-15 to WMD-100 pumps. DC motors typically run cooler and are generally smaller than AC motors offering designers the ability to reduce space requirements. DC motors can be controlled by speed to optimize pump performance to meet specific system requirements. Now OEM equipment designers can take advantage of our complete family of WMD pumps when they require DC drive motors.
 
Additional Impellers Available

Iwaki America offers specialized impeller designs that provide specific performance curve shapes. Our 6Z, 20Z, 30Z and 70Z are prime examples of designs that provide low flow high discharge pressure curve shapes.  For OEM applications we can design an impeller to meet a specific duty point and curve shape to meet your needs. By designing an application specific impeller we may be able to also offer a smaller package product where space is limited.

Contact us if you don't find what you need in the pump curves listed for our MD series. We'll help develop a pump solution to meet your specific needs.

Features
 
  • High Efficiencies make WMD & MD the clear choice inOEM fluid circulation and transfer applications.

  • Choose standard alumina ceramic bearing materials and polypropylene, or optional SiC (silicon carbide) and ETFE (fluoropolymer) for your most aggressive solutions or highest purity requirements.

  • Iwaki America offers OEMs pumps that are compact, quiet, and long lasting for your Laser, Chiller, Personal Cooling and Medical Analyzer Applications.

  • Motor Matching - Offering more motor/pump configurations than any other manufacturer easily allows tailored pump solutions to meet your application needs. 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 allows the product to be used in a worldwide market. PSC or shaded pole AC motors are standard. Brushed and brushless motors are available for DC applications.
