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.
The foundations of Kirloskar Brothers Limited, the flagship company of the Kirloskar Group, were established in 1888 by Laxmanrao Kirloskar and his partner Ramuanna.

Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

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.
