Q. What is a free standing baseplate and when should it be used? Are there any special design requirements?
Questions are answered about monitoring power consumption and noise level parameters for pumps.
Injection of Air to Reduce Noise and Damage How Much Does an Inducer Reduce NPSHR? NPSH Requirements of a Reciprocating Pump
Most pumps are not suitable for handling any significant quantity of free gas.
The concept of “suction energy” was developed to enhance the evaluation of the NPSH characteristics of centrifugal pumps, but I fear that it misses the mark.
For the non-expert in pump technology, selecting the most appropriate pump technology for a specific application or process system can be challenging because.
Packaged pump systems are gaining popularity due to their space saving design, simplified installation, single source responsibility and advanced control options with communication ability.
The NPSH curve is roughly a lazy "U," reaching a minimum value at a capacity Q about 40 percent of the best‑efficiency capacity.
A refinery's vertical pump passes the test, verifying its performance before installation.
If pump cavitation is not detected and quickly eliminated, significant damage can occur to the impeller and other internal components. Since cavitation (the formation and collapse of vapor bubbles in the pumped fluid as it passes through the pump impeller) is often temporary or even induced by the process, timely knowledge of the condition is extremely important so operators can act to alleviate the problem and prevent damage.
I have seen, and I am sure you have too, countless examples of installed pumps that are poor hydraulic fits. These selection mistakes are called off-design pump selections, bad actors, misapplied pumps, etc.
Due to high specific gravity, viscosity and particle size of mining materials, centrifugal pumps are continuously challenged in mining applications.
