FIELD: pumps.
SUBSTANCE: invention relates to peristaltic pumps with electromagnetic drive and is intended for use in oil industry, particularly in collecting fluid from a well. Peristaltic pump comprises a central body arranged inside an elastic body, electromagnets arranged along pump axis. Electromagnets envelope hydraulic chamber. Armatures of electromagnets are connected with pistons fitted on hydraulic chambers filled with liquid. Inside hydraulic chambers are arranged elastic bodies with central bodies. Simplified design.
EFFECT: higher efficiency of peristaltic pump, at which it is possible to obtain high pressure of pumped liquid.
