need help with water pump problem

I have recently installed 2 new water pumps to the galley sink; one to the cold faucet and the other to a ozone water purifyer. Both pumps advertise that they do not need an accumulator tank. The pressure is controled by varying the motor speed. Both pumps deliver the water in a rapid pulsating stream. Any ideas as to what the problem is or where to start?
Have a Great Day !

Re: need help with water pump problem

What kind of pumps are they? From your description I'm guessing diaphragm pumps. If so, that may be how they will pump, depending on the design. If one large diaphragm and one pair of valves (one in, one out) then by the nature of the pump the output will pulse.

I have a Jabsco diaphragm pump that has a multisection diaphragm is essentially four small pumps running off the one motor so the output is much smoother. An impeller type pump would also give a smoother output.

Any air in the suction will cause what you describe.
