A lift station in which there is a single tank. Pumps can be installed in a wet well lift station in either a suction lift or suction head condition.

SUCTION LIFT
The combination of static suction lift and friction head in the suction piping when the source of liquid is below the pump centerline.

GAGE PRESSURE
The pressure measured relative to the local atmospheric pressure. Gage pressure may be negative. A negative gage pressure is known as suction or vacuum.
|
RESERVOIR FILTER
A filter installed in a reservoir in series with a suction or return line. Also known as sump filter.
|
STATIC SUTION LIFT
The distance from the pump's centerline to a liquid surface on the suction side in case of pump placed above the liquid level.
|
SEALLESS PUMP
A centrifugal pump with impellers that have magnetic hubs to provide speed and positional control. Sealless pump should be installed so it has a ans. suction head.
|
NPSH
This is the abbreviation for Net Positive Suction Head. This is an expression used in cargo pumping calculations. It is the pressure at the pump inlet and is the combination of the liquid head plus the pressure in the vapor space.
|
SUTION HEAD
The distance from the pump's centerline to a liquid surface on the suction side when pump located below the liquid level.
|
SUCTION PRESSURE REGULATOR
An automatic valve designed to limit the suction pressure to prevent compressor overload.
|
DRY TYPE EVAPORATOR
An evaporator of the continuous tube type where liquid refrigerant from a pressure-reducing device is fed into one end and the compressor suction line at the outlet removes the dry refrigerant vapour.
|
LANTERN RING
A brass rings for letting fluid to be equally distributed around shaft for cooling and lubricating the packing. Adds in sealing the pump from air leaks up the shaft if the pump is working with a suction lift.
