Need advice on what type of hose to use from the high pressure (engine-driven) pump to the membrane housing. That is, carrying the sea water
, under about 800psi, to the membrane.
I have burst two hoses already in the past 2 years, due to vibration/chafing on metal bulkhead caused by the pulsing set up with the high pressure pump. I think I've corrected the chafe issue.
When I arrived here in the Philippines
I had some new hoses and fittings made up but they are for hydraulic fluid. I've read elsewhere in this forum that hydraulic hoses are not well-suited for this purpose (taste?) but I have this to add: I replaced a short section of hose (1 foot) running from the sea water
strainer intake to the first-in-line filter housing with a chunk of hydraulic hose that I picked up in Chile
. After about 6 months first filter (20 mic?) was filthy black and the 2nd ( 5mic) filter looked ok. The only reason I can think of for this black crap is that the short section of hydraulic hose is shedding particles (a sea water problem?). This worries me and I will change that 1 foot section and it further worries me that my new hydraulic hose (not yet installed) from high pressure pump to membrane would be worse disaster, fouling the membranes in short order.
So, back to original question: what is accepted standard for hose from high pressure pump to membrane (and from membrane to control panel)?
I looked at the Parker hose site but the choices are almost limitless and I am not an engineer
Thanks for any help.
