water & oil pumps
A pump is a device used to move fluids, such as liquids or
slurries, or gases. A pump displaces a volume by physical or
mechanical action. One common misconception about pumps
is the thought that they create pressure. Pumps alone do not
create pressure; they only displace fluid, causing a flow.
Adding resistance to flow causes pressure. Pumps fall into five
major groups: direct lift, displacement, velocity, buoyancy and
gravity pumps.

Industrial water treatment seeks to manage four main problem
areas: scaling, corrosion, microbiological activity and disposal
of residual wastewater. Boilers do not have many problems
with microbes as the high temperatures prevents their growth.
The oil pump usually sucks the oil out of the engine's oil pan
through a wire mesh strainer; and pumps the oil through an oil
filter before it goes to the bearings.
