How to maximize load on a pump?
(OP)
I want to test a pump with worst case scenario. Right now, I have raised the discharge pipe to height of about 2 ft to increase the load on pump.
Would raising the inlet to about same height as that of discharge increase the load?
What other factors can increase the load on pump? Thanks.

RE: How to maximize load on a pump?
The only ways to increase the load are to increase the head/pressure, increase the viscosity or to increase the flow rate.
How much more load do you want to apply? 2 ft is not very much at all!
RE: How to maximize load on a pump?
The load on a pump (if it is synonymous to the power drawn) is maximum when there is no resistance to the fluid flow i.e open discharge condition without piping. Raising the inlet pipe doesn't mean anything to me unless I see the schematic.
High density liquid pumping require higher power.

CAREFUL - that also translate into more NPSH Required by the pump - therefore be carefull not to take the pump beyond what the existing NPSHA permits !

People have complained that the pump sometimes turns off. I have not found this to be the case since I was testing this under normal conditions. I was wondering increasing load might cause it to fail.
By increasing load on pump I mean increasing electrical consumption.

By saying "the pump turns off" do you mean the motor trips ?
Higher viscosities, such as when trying to pump cold liquids may result in motor outages. Would you kindly add details on the fluid involved and the operating conditions ?
