PumpSmart,
Indeed, the motor is a Reliance submersible motor. The pump is a Goulds. They are connected via a gearbox. All data included with original post is correct.
Chicopee, the pump performance curve was generated from the company that the custom pump/motor combination is being purchased from. The "system curve" on the pump performance curve is actually the power. I think it is motor horsepower and not brake horsepower though the graph doesn't really say.
Thanks for answering my post, BigInch!
Top part of spreadsheet is from test with water with SG=1. Bottom part of spreadsheet is me trying to calculate what motor requirement would be at test points if pump encountered fluid with SG=1.25. The motor that was provided is a 100 HP 3-phase AC...
The pump is a submersible type with a design point of 139 gpm at 589 ft of head. The purpose is pumping out a wastewater tank with worst case fluid properties of SG = 1.25 and viscosity = 3.0 cP. It is designed to operate from 1' - 45' of submergence as measured from the bottom of the suction...
BigInch, thanks for your input. You've kind of got to the reason I want to analyze these test results. I would like to have some engineering analysis to support why a gravity fill of in-place piping may not work. The air displacement certainly seems to be a big part of it. For runs greater...
Hi all,
I've been banging my head against the wall with this one and can't seem to get it.
Background: I am a mechanical engineer working for a federal agency reviewing a test report regarding grout formulation provided to us by a contractor. The grout will be for waste stabilization of...
