Pump Hous Intake design
(OP)
Hi everybody,
What do you think about a pump house intake design with two vertcal turbine pumps positioned in line, one behind the other, in a narrow channel.
Any comments?

as you can see from the comments already - an installation like this is suspect.

if one pump is off, then that stationary pump is just uselessly adding losses as the water has to be pumped through these tight clearances.
if you think you need two pumps for that much extra head, you should get a bigger bowl and add more stages to the VTP.
if you think you need a standby pump in series incase of more head needed later, a vtp on top of it is not a good idea, neither is a vtp mounted horizontally else where.. what i would do is have a horizontal centri pump down the line, as many as you need. Have 2 parallel lines with valves to control the path of liquid, so when you need the pumps, you can control the fluid to go in the pumps line and switch on the pumps.
two vtps in serial? i dont think so

For interest - what size pump units are you talking about.

For testing - be careful. Check pressure, flows and vibration readings. If you see any problems on testing - they will never work. If you run through the tests ok - put on vibration sensors and hook them into your control panel for constant monitoring and automatic shutdown.
If one pump chokes off the other - expect cavitation and turbulence, heavy vibration will take out the bearings, and maybe the whole rotating assembly.
