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.<ref name="mccomb">{{Citation | last = McComb | first = Gordon | last2 = Shamieh | first2 = Cathleen | title = Electronics For Dummies | page = 251 | publisher = For Dummies | year = 2009 | edition = 2nd | url = https://books.google.com/books?id=0yJ3blaI7b8C&pg=PA251 | isbn = 978-0-470-28697-5 | postscript =.}}</ref> (An electrically operated pump for this purpose would usually be called a [[vacuum pump]].)

The plunger type has a cylinder with a [[spring (device)|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 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.
