Designing a New Pump for a Water Resources Pumping Plant.
Enterprising biosolids pump manufacturers are finding abundant new opportunities in the biosolids segment. With wastewater management becoming a key issue, everyone from truck owners to sludge treatment solution providers is trying to take advantage of the growing biosolids market.
Q. What can be done to avoid the high-pressure differential from rupturing the diaphragm in reciprocating diaphragm pumps?
Pumps & Systems , November 2007
Our repair shop came upon a customer that purposely buys oversized pumps and immediately operates them at nearly 80 percent closed valve. Each year, after the hot days of summer simmer down, they evaluate the pumps' performance by measuring flow. If the flow dropped by more than ~10 percent, they slightly open the valve (say 70 percent closed) to compensate and run the pump at this new valve position the next season.
Product type and environment must be considered when choosing the proper pump.
We all know that a pump operating at off-design (to the left or right of the best efficiency point—BEP) flow wastes energy. But how much?
Positive displacement pumps are used in a myriad of applications across multiple industries. Users have found them to be the solution to many specific pumping challenges; however, due to their size, simplicity and ruggedness, they often are not as well understood as other pump types.
A brand new internal gear pump is started up and the flow delivery is 30 percent to 40 percent below rated capacity, and the pump is making a loud chattering noise.
