PD pump (Rotary lobe pump) -- loud noise
Reply to thread
Message
[QUOTE="Theerapat, post: 6044425, member: 649777"] We have already tried lowering the pump speed, the noise went away at 25 Hz (around 175 rpm). What I wondered is that we have such a high inlet pressure and the liquid is still not entering the pump sufficiently. If we can lift the liquid tank higher and increase the inlet pressure will it help? [/QUOTE]
