The submersible centrifugal electric pump ETsV is intended for rising of water from artesian wells for the purpose of implementation of water supply, irrigation and other works.
The submersible centrifugal electric pump ETsV is intended for rising of water from artesian wells for the purpose of implementation of water supply, irrigation and other similar works.
The electric pump ETsV is intended for rising of water with the general mineralization (the dry rest) of no more than 1500 mg/l, with a hydrogen indicator (rn) from 6,5 to 9,5, with the temperature up to 25 °C, a mass fraction of solid mechanical impurity - no more than 0,01% , with the content of chlorides — no more than 350 mg/l, sulfates — no more than 500 mg/l, hydrogen sulfide — no more than 1,5 mg/l.
Design features of the upgraded electric pumps:
- all electric pumps have axial unloading that increases bearing service life till 30000 o'clock;
- application for a winding of the electric motor of a heatresistant wire allows to increase temperature of operation of the electric motor and to increase its service life;
- performance of a winding of a rotor by a tear - shaped copper profile allows to reduce its heating at the same dimensions of the electric motor, to increase its service life and efficiency;
- increase in giving of 8 inch pumps up to 65 m/h, 10 inch to 160 m3/h allows to save means when drilling new wells. Costs of arrangement of the 8th inch well instead of 10 inch at the expense of a difference in the cost of boring works and casing pipes are made by not less than 40% .
- all plastic driving wheels are reinforced by stainless steel that increases their wear resistance and durability;
- 10 and 12 inch driving wheels are manufactured of stainless steel; use for production of plastic details of a leksan and a noril of import production which has twice the big durability than traditional plastic, allows to increase durability and reliability of the electric pump;
- 4 inch and household electric pumps are manufactured in corrosion - proof execution;
- household electric pumps are equipped with the built - in thermal protection, work on its introduction on other types of pumps is also carried out;
- bearings from the siliconized graphite and sealing by means of face consolidation are used to increase in service life of household electric motors in them.
- due to use of modern technologies of the price of new pumps do not exceed traditional.
We complete pumps with stations of management and protection, sensors of the dry course and level, a runway cable.
