... measure the pressures between discharge and suction, with some adjustments for pipe velocities, gage elevations, etc. Flow is a bit more challenging since most field installations do not have flowmet...

...differences in piping between (A) and (B). Since the pipe on unit (A) is not submerged under the water level, the pump needs to always push against 25 - 15 = 10-ft static head (plus friction). Unit (B...

... cover anything relating misalignment to vibrations. Thus, I must unfortunately dismiss this as an irrelevant source on this specific subject (although it is a very good study otherwise), and ask Mr. ...

...port the entire rotor (impeller, shaft, sleeves). For end-suction designs, the impeller is cantilevered against the inner bearing. On the positive side, there is no restriction to incoming flow...

...Typically, only one bearing near the discharge (drive) side is provided, so the entire rotor sits cantilever at a tight clearance required to keep water from flowing back. Eventually, the rotor...

...orry much about spills and catastrophic failures, and periodically changed packings. Despite vibration levels being around ~0.7-in/sec (pumps were held to the sole plates by only half the number of bo...

...r this sort of strategy. To clarify and unify expectations, a good starting point is to have a 3-level set of specifications prepared for the vertical turbine pump repair/overhaul/upgrade work. ...
