PeakOfPerfection posted a topic in General DiscussionThis thread will be to show the most basic layout drawings for tanks, plumbing, etc. Normally this would go in the Members section...however, newbies need at least *some* basic knowledge and nothing here isn't available online with about 5 minutes of searching. HOWEVER... If you are new...just join as a Premium member. Seriously, it is a heck of an investment. Ask most any Premium. The amount of knowledge and detailed information you will find on pumps, accessories, layouts, how to keep things running, chemicals, marketing and SEO...is absolutely 1000% worth it. Premium membership will save you money and it will make you money. Meantime, I will leave this thread open for drawings and system layout images. Please leave extensive discussions of different types of systems to different threads to keep this reasonably simple to navigate. If you have specific questions on a specific layout, please ask. If anybody wants to contribute their own layout drawings or pictures, please do so. Oh...and ANYBODY who tries to start the Top Vs. Bottom Bulkhead argument will be strung up by their Petard and pelted mercilessly with rotted fruits and vegetables. *************** Here are some universal guidelines applicable to ALL pump setups: 1) The Sealed Tank design shown should be utilized on ALL rigs. There are far too many posts on Facebook, and Pressure washing forums of guys who are suffering suspension and frame failures. Using this design will eliminate most of the corrosion. It is only a matter of time before there is a serious injury caused by a rig failure due to corrosion. Seeing as how the sealed tank system is so easy and affordable to implement and it will significantly cut down on your equipment and rig corrosion, it is silly to NOT do it. 2) Ideal Suction Line Sizing for Pumps. Suction line should be PVC. PVC Polybraid or Spiral Wrap are the most popular options. 3/8 pump: 3/4" 1/2" Pump. 1" 1" Pumps. 1" Note: 1" Air diaphragm pumps run fine with 1" input lines as long as they are driven with reasonable CFM. 3) Grey Schedule 80 PVC is the preferred material for hard pipes. Schedule 80 is thicker, stronger and more UV resistant. All PVC will eventually degrade from UV if not coated. 4) All pumps should have at least a small section of flexible input and output lines going directly in and out of the pumps. This is especially true for Air Diaphragm and Udor types. 5) All pumps with the exception of Kynar Air Diaphragm pumps with Teflon Diaphragms should be rinsed with fresh water after spraying. Even with a Kynar pump, your hose fittings are typically stainless and will rust if not rinsed...so just rinse with fresh water already! 6) Vented Chemical rated ball valves last longer. They are more expensive. The cheap PVC ball valves you buy at Lowes won't last with SH and get stiff and break. Invest in a good valve and it will last. I am on year five with our original 3 way Spears Schedule 80 Chlorine service vented ball valve. It was stupid expensive, but it still works perfectly and doesn't leak a drop. 7) If you use Banjo valves, you must use the Teflon ball/Viton seal version. The Buna Rubber seal version will leak...rapidly. 8) Trigger guns don't last. We nearly all use Ball valves. See note on Schedule 80 or use a Poly Banjo valve at the spray hose end. They won't break as easily if dropped. 9) *Most* metal will rust in the presence of SH. Anything exposed to SH fumes or direct spray should be coated. Hastelloy, Titanium and Tantalum are the non radioactive exceptions. If you have to ask the price... 10) Thread sealer containing Teflon is far preferable over Teflon tape for all fluid connections. Air Connections are fine with Teflon Tape. I use Gasoila for all my low pressure fluid sealing. 11. You need water hose on your truck. Buy Eley Polyurethane Hose or Flexzilla. I run Flexzilla. 12. Check all fittings thoroughly on a regular basis. Test all new fittings with water under pressure with the pump spraying. Materials Guide. Materials from least to most resistant to Chlorine and wear. Pump Materials: Fiberglass Reinforced Polypropylene....Virgin Polypropylene...FKM/Viton...PVC...Teflon/Kalrez...PVDF/Kynar Metals: Steel/Iron...Aluminum...Stainless Steel...Hastelloy C...Titanium...Tantalum. Spray Hose: Polybraid...Polyurethane...PVC Blend.
Here is a John Blue gas powered roof cleaning pump http://www.dultmeier.com/products/search/7807 It is only 700.00, and bolts right on a small 2.5 to 3hp Honda motor, or you can use the harbor freight predator motor. It is nearly 300 psi, so it will shoot a long way. As a rule, I like air powered roof cleaning pumps better, because they are more reliable. For a Gas powered roof cleaning pump, these are more relaible then a UDOR Roof Cleaning Pump, and cost about 1/2 as much.
