Pressure tanks are a low-priced, simple and effective of gear
that will help protect your pump and provide you with a good steady pressure
and flow of water for whatever application you need.
Select a pump that has a flow and pressure that is better
suited to the job you are trying to do. A
pressure tank can be installed anywhere with the check valve. This allows a
pressure pump to build up pressure and let the automatic switch turn it off. When
all the taps in the system are shut, then the pressure in the system builds. This
can be installed on the suction side or just after the pump on the outlet. The
check valve stops water flowing backwards and the pressure dropping when the pumps
turn off. The pressure tank also provides a shock absorb er effect in that the
rubber diaphragm flexes so that pressure spikes are not as noticeable. It also
stops the effect of water hammer. Install a pump with a variable speed motor
along with pressure tank.
Booster pumps are usually piston or plunger type
compressors. A single-acting, single-stage booster is the simplest
configuration, and comprises a cylinder, designed to withstand the operating
pressures, with a piston which is driven back and forth inside the cylinder. A variable speed pump measures the demand for
flow and when less is required it slows down to meet the demand. This can be
expensive and need a fairly complex piece of electrical equipment to work.
