Yamada Corrosion Guide
Yamada Corrosion Guide This booklet is intended as a general guide in the selections of proper pump materials. This listing includes the most common liquids used in industrial and processing applications.
Fluid Velocities
Fluid Velocities – “What’s that screaming noise? It’s one thing to receive “rules of thumb” from people on pump design, but sometimes you have to see it to really understand it. The Cameron Hydraulic Handbook is an indispensable tool. One key variable for which we control when sizing a pump is fluid velocity. It is […]
NPSHr and NPSHa
NPSHr and NPSHa Net Positive Suction head available vs required On a washer job we had a Gusher Vortex Pump back where the prime level was right at the high level alarm, not by design but because required water levels were not maintained. So we had a situation where NPSHa was scary close to NPSHr. […]
When the Cottonwoods Bloom
When the Cottonwoods Bloom Manufacturing plants located in wooded setting can hold a certain charm to them, the co-existence of nature and machinery. One day we got a call that the Tranter plate-frame heat exchanger was not working properly. A quick investigation revealed that the cooling tower water was not delivering water at its design […]
Platecoil
Platecoil Caught holding the bag – Using plastics when you should have been using stainless Tranter Platecoil is most often used to either heat or cool a manufacturing process liquid. When your process liquid needs to be cooled, Platecoil is most often immersed in a tank with a cooler liquid/gas circulating through the Platecoil. When […]
Loss of Pressure
Loss of Pressure New washers and central coolant systems On a new system it is not uncommon to get a call that a pump isn’t putting out adequate pressure. When we investigate we often find the culprit is high levels on entrained air. Pumps will deliver significantly less pressure when even 1-2% air is in […]
Low Pressure – Too Many Headers
Low Pressure – Too Many Headers When pumps are on large systems involving many components, initial start up is a time of both excitement and anxiety. WheN mishaps occur, resolution can’t come fast enough especially when on a brand new $100 million paint operation. We were starting up a new system in an automotive paint […]
Centrifugal Pump Troubleshooting
Centrifugal Pump Troubleshooting Condition Possible cause(s) No fluid is delivered Pump is not primedSpeed is too lowRequired discharge head is too high compared to pump designSuction line or strainer is cloggedImpeller is completely clogged Wrong pump rotation direction / motor wired wrongToo much clearance between impeller and intake flange Not enough fluid is delivered Air leaks […]
How To Kill A Centrifugal Pump
How to Kill a Centrifugal Pump Of course this is something nobody wants to do, tries to do. But it happens. And no doubt many people have troubleshot a failing system, come up with an idea, and then think to themselves, “I wonder what this would do to the pump?” We’ve seen a lot and […]
