ELECTROMAGNETIC PUMP AND ELECTROMAGNETIC PUMP SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic pump easily removing earth and sand and sludge even if the pump is clogged with them and easily replacing or easily cleaning most of an area with which fluid is brought into contact when the fluid is pumped up by the pump with respect to each sampling point.

SOLUTION: This electromagnetic pump includes: a cylindrical member formed into a hollow cylindrical shape; a coil member wound in the peripheral direction of the cylindrical member and functioning as an electromagnet; and a magnetic piston member with the hollow portion of the cylindrical member axially slidably housed. A first check valve is provided to at least one of the axial ends of the cylindrical member. The piston member is provided with a through-hole passing through a direction along a sliding direction and a second check valve provided in the through-hole.
