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.
Slow pump pressure is the circulating pressure (pressure used to pump fluid through the whole active fluid system, including the borehole and all the surface tanks that constitute the primary system during drilling) at a reduced rate. SPP is very important during a well kill operation in which circulation (a process in which drilling fluid is ...

The Pulsometer steam pump is a pistonless pump which was patented in 1872 [2] by American Charles Henry Hall. In 1875 a British engineer bought the patent rights of the Pulsometer [3] and it was introduced to the market soon thereafter. The invention was inspired by the Savery steam pump invented by Thomas Savery.
