Electric pump Burun N1V is intended for pumping water with temperature up to 35°С and also other liquids having mechanical admixtures is up to 5% by mass and up to 2 mm in size .
The electric pump can be used for irrigation works, cleaning of different capacities, in technological processes, except drinking water-supply.
Pump is manufactured in single-phase version with voltage 220V and in three-phase version with voltage 380V.
Pump is not intended for operation in explosive and fire-hazardous premises.
Electric pump related to the items of aspect 1 (repairable ones) as per GOST 27.003-90.
Climatic version U1.1 GOST15150-69.
Operating mode is continuous.
Electric pump consists of electric motor and pump part.
Pump part consists of case, screw, rubber movable shell and lamp.
Screw is fixed rigidly on the shaft by glue«Loctite».
The screw of the pump is a single-threaded one, its any cross-section is a circle, the centre of which is shift relatively to the axis by magnitude of eccentricity.
During rotation of the screw in the shell the liquid displaces between screw and shell.
The tail of the screw is sealed by cuff. Electric pump is installed on rubber shock absorbers.
The design of the electric pump provided the handle for transportation.
Start-up of the electric pump of single-phase execution is carried out by means of the starting device mounted on a power cord. The starting device has a start button, starting condenser, the relay for protection of the electric motor against overloads and the reinforced power cord for connection single-phase mains.
The electric pump in three-phase execution is connected to power main via the time cut-out (is not included into delivery set).
The electric pump belongs to items of protection class I against defeat by an electric current.
