SOLAR PUMPING MACHINERY

Supply , Erection , Commissioning and testing of Submersible solar AC Pump of MNRE approved Solar AC pump of reputemake i.e.KSB/Gurndfus. The submersible pump should be suitable for pumping clean water . All the components should be made in stainless steel grade EN 1.4301 (AiSi 304) that ensures high corrosive resistance . The pump should be coupled with suitable motor with sand shield , mechnical shaft seal,water lubricated journal bearings and a volume compensating diaphargm . The motor should be fitted with tempcon temperature sensor device that include a NTC resistor which senses the temperature by use of powerline communication together with a control panel ,enables temperature monitoring. The rssistor should built -in close to the winding. The temperature is converted in to high frequency sibnal which is sent via the subersible drop cable and which can be converted into a temperature reading by means of control panel . The stator should be hermetically encapsulated in stainless steel and the windings are embedded in polymer compound resulting high mechnical stability ,optimum cooling and reduces the risk of short circuits in the windings .The shaft seal faces should be ceramic/ carbon, this material combination provides good dry running resistance togetherwith the shaft seal housing ,the sand shield forms a labyrinth seal , which during normal operating conditions prevents penetration of sand particle into the shaft seal . The Motor should be canned type submerible motor offering good mechnical stability and high efficiency .suitable for temperatures upto 40 degree celsius.The pump should be suitable for data given below :- .
