Air Pump Q

[gug54321]

Hi all

i have recently noticed that air pump hasnt been throwing out as much as used to be, so apart it cam and repaired a split in one of the diaphragms, its a twin outlet pump and one diaphragm does one outlet and the other does the other outlet, what i want to know it weather i can link the 2 outlets to get more pressure to my bubble wall that i have or do they have to run separately?

cheers

It would be best, from a flow restriction standpoint, to run the air lines separately as far as you can before combining them into a single tube. Each length of that single tube will cause significant pressure losses if it is seeing the flow of both diaphragms. There are 2 replacement parts in a common vibrating air pump that are meant to be replaced to get the pump working right again. One is the diaphragm, which you seem to have discovered, the other is the small flap that acts as a check valve and is located between the diaphragm chamber and where the air leaves the air pump. My present air pumps have given me no trouble so they have not been taken apart, but the ones I used to need to work on every year or so had thin flexible plastic valves that were just held in place by a simple tiny chunk of rubbery material.

yes i have put the join about 2' away from the pump, the check valves seem to be working fine still and i dont think i should get the diaphragms fighting eachother as they seem to pump at opposites if you get what i mean
