PUMP Russian patent published in 2007 - IPC F04F1/04 F24J2/42 

FIELD: equipment used for rising of water from wells and holes.

SUBSTANCE: pump has cylinder with bottom equipped with suction valve and filter, and head with inlet branch pipe connected to air pipeline, and discharge branch pipe connected to liquid pipeline and equipped with return valve, cycle frequency regulator formed as reservoir unbalanced on axis of rotation, and throughput-capacity regulator. Pipelines are positioned within casing. End of liquid pipeline is communicating with cycle frequency regulator. Pump is provided with compressor and vacuum pump, and free end of air pipeline is connected with discharge branch pipe of compressor and simultaneously with inlet branch pipe of vacuum pump. Cylinder is formed from pipe length whose outer diameter is 1.1-1.17 of inner diameter of casing. Reservoir of cycle frequency regulator is positioned above reservoir of storehouse. Throughput-capacity regulator is connected to reservoir of cycle frequency regulator and is made in the form of valve with division scale or without it, or in the form of shutter with division scale or without it.

EFFECT: increased efficiency and improved operating conditions.
