Thermodynamic pump testing is a form of pump testing where only the temperature rise, power consumed, and differential pressure need to be measured to find the efficiency of a pump. These measurements are typically made with insertion temperature probes and pressure probes fitted to tapping points on the pump's inlet and outlet. [ 1 ]
In hydrogeology, an aquifer test (or a pumping test) is conducted to evaluate an aquifer by "stimulating" the aquifer through constant pumping, and observing the aquifer's "response" in observation wells. Aquifer testing is a common tool that hydrogeologists use to characterize a system of aquifers, aquitards and flow system boundaries.
Specific Pump Power (SPP) is a metric in fluid dynamics that quantifies the energy-efficiency of pump systems. It is a measure of the electric power that is needed to operate a pump (or collection of pumps), relative to the volume flow rate. It is not constant for a given pump, but changes with both flow rate and pump pressure.
Hydraulic ram, System Lambach now at Roscheider Hof Open Air Museum The first US patent was issued to Joseph Cerneau (or Curneau) and Stephen (Étienne) S. Hallet (1755-1825) in 1809. [ 7 ] [ 8 ] US interest in hydraulic rams picked up around 1840, as further patents were issued and domestic companies started offering rams for sale.
The basic function of a pump is to do work on a liquid. It can be used to transport and compress a liquid. In industries heavy-duty pumps are used to move water, chemicals, slurry, food, oil and so on. Depending on their action, pumps are classified into two types — Centrifugal Pumps and Positive Displacement Pumps. While centrifugal pumps ...

Aquifer test (or a pumping test) is a field experiment in which a well is pumped at a controlled rate and the aquifer's response (drawdown) is measured in one or more observation wells. [5] Cone of depression is a conically-shaped depression that is produced in a water table as a result of pumping water from a well at a given rate. [4]
Hydropneumatic pump controllers provide a Means of control for multiple fixed delivery volume, low cost low complexity pumps; to provide variable flow as required by small (say +/- 10 psi) pressure increase or decrease of a system. Means of control for pump unloading / recirculation against no pressure, without electric pressure switches.
