MOTOVARIO – Mechanical Speed Variator. Manual Control only. Has 1:0:67 throughput reduction , so pump has to be sized with physically larger pumphead to give comparable flow rate to standard ( Fixed flow ) pump.
Typical Control range is 17-100% but some applications may call for a motor size/type which will only permit 28-100% control range.
Transmission losses typically require a larger motor (than standard) to be fitted in order to maintain same pressure performance.
MV, in most cases , is the least cost option we offer.
