Pumps: Iwaki MD Pumps & Iwaki WMD Pumps
  • Iwaki Pumps, RLT type, handle back pressure better and can be used for almost any application. Especially recommended for high-head situations or when using cartridge (pressure) filters.
  • Iwaki Pumps, RLXT type, are best suited for circulation only - that is, where water encounters very little back pressure--for example, returning water from a sump. Excellent where a high turn-over rate is desired.
  • Iwaki Pumps, WMD, have American Made Motors
  • Iwaki Pumps, MD, have Japanese Made Motors

We carry Iwaki MD & WMD pump replacement parts
