OH3 and OH4

[extremechanical]

Hi all,

How much extra ( approx) and OH3 model costs when compared to OH 4 Pump for the same capacity

I know I have not provided any data , I am just asking this info approximately please

It would be nice if you provided more detail but I will explain the difference first.
OH3: This is a vertical in-line pump with flexible coupling (you can remove the pump from motor easily).
OH4: This is a vertical in-line pump with permanent rigid coupling (not removable).

By definition, the price difference should not be significant. You should really make sure it fits your application. As compared with flexible couplings, rigid couplings have limited application. Rigid couplings do not have the ability to compensate for shaft misalignments and are used where shafts are already positioned in precise lateral and angular alignment. I hope this helps. Goodluck!

Thanks a lot!
