Dear Peter, This noise could be due to the presence of some air in the pump. Before call any service, try to flux about 100 ml of 100% methanol (or ethanol if you don’t like to use methanol) at 10 ml/min and 5 ml/min (50:50). This should be remove any bubble. If the noise persist, the pump probably need a cleaning and maintenance.

Hearing some high pitched sounds coming from the pump when we're running it. Line A seems clogged and makes a thudding noise when we try to do a pump wash through that line. Does anyone have any experience w/fixing one/replacing the pump? Or any idea how much it's going to set us back to get it fixed? Sorry for the off topic question/thanks in advance for any thoughts and ideas.
