Twin Impeller Shower Pump

Zoomup
Ref. Grundfoss STP-2.0B twin impeller shower pump. 2.2 Amp. 510 Watts. 240 Volts.


Will this pump be o.k. run through a B6 M.C.B. or will it trip the B6 on starting do you think?


Thanks,


Z.

    In the animal kingdom, the giraffe, but it has a long length of thin plumbing between heart and head, so I imagine the highest blood pressure is measured at the giraffe ankle when it is standing up. At the head end it will be less, and I understand they have special valves to prevent them fainting when they stand up suddenly. (the giraffe not the manager and SDA.)




    Yes indeed! As the tallest animal, it needs to pump the blood up to head height, from whence it falls back to the heart - it cannot be sucked back because the veins would collapse. It doesn't have to pump the blood to the feet, but it does need enough pressure to overcome the resistance of the circuit.


    Back to the electrical and plumbing analogy, the issue here is where is your point of reference? Conventionally, blood pressure is taken at the level of the heart and compared with atmospheric.


    Back to valves (thermionic or semiconductor, if you prefer) do giraffes get varicose veins? ?


    Blue whale is an interesting suggestion, but without Googling the subject, I expect that it would be quite low given that they are usually horizontal and immersed.
