A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style.[1] (An electrically-operated pump for this purpose would usually be called a vacuum pump.)
The plunger type has a cylinder with a spring-loaded piston which is pushed down and locks into place. When triggered by pressing a button, the piston springs up, creating suction that sucks the solder off the soldered connection. The plunger type is what we have displayed here for sell .
The bulb type creates suction by squeezing and releasing a rubber bulb.
The pump is applied to a heated solder connection, then operated to suck the solder away.
