at one of our client site, we have a centrifugal pump of capacity 800 gpm and 35 mtrs head for pumping condenser water. condenser water is supplied to package units and returned back to the cooling tower. The package units (20 no's) are provided only with gate valves.

hi quark,
the design head is 27.5mtrs.
but the actual head we measured from the difference between pump discharge and suction pressure gauges is 25mtrs.
but what i said as the building height is 31 mtrs the chilled water flow was sufficient at the topmost level with 25 mtrs head.
in case if i...
hi quark,
i wont be able to trim the impeller, as the same pump might be required for future(highcapacitychillers).
the option is installing a vfd.
incase if i reduced the flow and the head changed from 25 mtrs to 19mtrs will the flow reach the topmost part of the building.
the building height...
hi,
we have a primary chilled water system, with a constant flow pump.
the head required is 27.5metres and 750 gallons.
but presently the pump delivers a flow of 900 gallons and 25metres head. chiller is of 300 tonne capacity.
so now i want to reduce the pump speed by installing a variable...
