Pumps—Shaft Sealing Systems for Centrifugal and Rotary Pumps
This standard specifies requirements and gives recommendations for sealing systems for centrifugal and rotary pumps used in the petroleum, natural gas, and chemical industries. See A.1.1 and A.1.2. It is the responsibility of the purchaser or seal vendor to ensure that the selected seal and auxiliaries are suitable for the intended service condition. It is applicable mainly for hazardous, flamm...
متن کاملDetecting Cavitation in Centrifugal Pumps
ently Nevada Corporation is continually investigating methods to help our customers protect and manage all their machinery. This includes integrated solutions to address machines of all sizes, speeds, and criticality. Within two of the largest markets that we serve, Hydrocarbon Processing and Power Generation, the most common machine type is the process pump. The vast majority of these pumps ar...
متن کاملThrombus Formation in Centrifugal Pumps
Three centrifugal flow pumps; the Biomedicus BP80, the Sarns Delphin and the Aries Lifestream 2100, were evaluated in vitro to determine each pump's individual tendencies for thrombus formation. Thrombogenic surfaces in the circuit were minimized by using heparin coated tubing and connectors. The centrifugal pumps, which were not heparin bonded, were placed in line in a circuit which consisted ...
متن کاملDetection of Cavitation in Centrifugal Pumps
Pumps are designed and manufactured to operate well away from the cavitation condition and thus the factors affecting the onset of cavitation are important. A specially designed test rig was and constructed so that the onset of cavitation could be studied visually while obtaining actual NPSH data. The magnitude of the NPSH level at 3% drop in total discharge head of a pump was determined at dif...
متن کاملElectric pumps and hyperbaric treatment.
To the Editor:—We read with interest the case report and the study of Sanchez-Guijo et al., which describes the failure of patient-controlled analgesia pumps in a hyperbaric environment. We have experience with this problem. Electronic infusion pumps function in a fashion similar to a patient-controlled analgesia pump. We have observed unexplained low blood pressure in some patients treated by ...
