Hi George, We have experienced the same problem out here in the wild wild (and very sandy) west. We found a filtering system that has relatively low back pressure and is automatic (self cleaning) for around 8 grand. I believe is was a three inch. Ron was going to look up the brand and contact information for you in the morning. It has been in service for about 10 months and we have not experienced any heating issues.

ASCOA paid $22k just expediting an order of em once, they must be Bentleys:) I'll check them and the source filtering. It is boost to "village" supply.

George, If you haven't already, try Hellan strainers http://www.hellanstrainer.com/. I've used them before, not with sand straining, but the unique design may be just what you're looking for. They claim they can filter out sand. Hellan is the Cadillac so the strainer could be pricey.

Ok, let me re-phrase- Anyone know how to filter sand out of a supply? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Matt Grise Sent: Thursday, February 04, 2010 5:29 PM To: '[email protected]' Subject: RE: sand strainer?

AFPsprink.com -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of George Church Sent: Thursday, February 04, 2010 4:32 PM To: [email protected] Subject: sand strainer? We've got a problem child project where sand in the water supply clogs up the cooling jacket on the diesel, and sand blasts the rubbers in valves so they drip. Small private water purveyor (the developer of the industrial park is the owner) supplies our diesel which then feeds the systems, all interior piping downstream of pump. Project located several miles from the ocean, a couple miles from the Bay. I can't imagine a strainer with perfs small enough to grab grains of sand and not have atrocious friction loss. I can't find cheesecloth to wrap around the strainer basket that's UL-Listed in a pump suction application. While I haven't encountered this before, it likely isn't the first time the problem has been encountered. Any one know a remedy other than a tank (with settling basin?) and higher pressure 2,500 GPM pump to make up for the loss of city residual pressure?
