Direct drive pumps NRD


The NRD-series is a complete revised version of established RD series. The external speed control (DC 1-5V) for more variability is now available for all models. The proved wet end parts of GFRPP(E) in combination with alumina ceramics/PTFE and EPDM/FKM allows now a temperature range up to 80°C for all NRD models. For more comfortable installation and assembly two thread connections (R and NPT) are now available additionally to the well-known tube fittings. IWAKI kept the brushless DC-drive with its smooth operation and a lifetime up to 15.000h. The further advantages of this concept are the compact sizes and light weight, especilly for NRD-20/30 with new motor housing material. The performance and characteristics of this seal less and leak free construction was approved only a little in view to present specifications and applications.
