Taco 007 with a circulator pump (Astm 10428-79 * E) are used to supply water to the total mineralization (dry residue) not more than 1500 mg / l, pH (pH) 6,5-9,5, temperature 25 ° C and solids content of mechanical impurities is not more than 0,01% by weight, chlorides – no more than 350 mg / l, sulfates – no more than 500 mg / l and hydrogen sulfide – not more than 1.5 mg / liter. In technically justified cases allowed to use pumps for water total mineralization of up to 2000 mg / liter.
The unit consists of a centrifugal pump and submersible motor shafts are connected by a rigid coupling. The circulator pump is located above the motor. Between the motor and pump is suction chamber with safety net. On execution of circulator pumps are single or multistage with a vertical shaft and work with pressurization. Values for each backwater pump under normal operating conditions are given in the specifications. Stage of the pump – or radial poluosevogo type. Pump and motor bearings are lubricated and cooled by water. The circulator pumps are equipped with check valves poppet or ball type and the special pressure port for connecting the unit to water-lifting pipe.
Submersible Taco motors, serving a drive circulator pumps , asynchronous squirrel cage, waterfull. The stator winding is connected with the phases in the “star” has three pins, that connect to the power supply cables.
Circulator pumps Taco 007-f5, Taco 007-sf5, Taco 007-f4 and Taco 007 pump curve performed with a cast stator winding insulation. Current mains voltage of 380 V / 50 Hz, three phase (except units with single-phase motors Taco 007 gpm and Taco 007 pump). Symbols pumps 007 is interpreted as follows:
The first figure – number of modifications (in the same conditions)
E – driven by a submersible Taco motor;
C – Centrifugal;
In – the water supply.
The numbers after the letters indicate the minimum allowable size for the inner diameter of the casing (well), decreased by 25 times and rounded mm
The following figures – supply, m3 / h and pressure, m
For pumps operating in a chemically active water or water with high temperature and contained in excess of established norms of mechanical impurities in the legend following numbers should be respectively added to the letters X, Tr, G.
Symbols of submersible Taco deciphered as follows:
The first figure – number of modifications of the motor:
B – waterfull
The numbers after the letters indicate the motor power, kW, and its greatest diameter,.
In the graphic characteristics of the pump shows:
Q – flow, m3 / h, H – head, m; N – power, kW; n-efficiency,%.
