Dear Sir,

M/S Hastinselectric has furnished an invaluable information through various URLs on Solar Pumps.

Within such a short period when we are getting excellent feed back thanks to CR4's efforts that through www.cr4.globalspec.com such helping talent is given a golden opportunity to serve the engineer brothers in distress.

Regards,

Ulhas Pradhan

If it is for India location Surya Solar located in Coimbatore and Central Electronics Limited could be useful. Hyderabad and Bangalore have a number of companies installing solar pv pumps. Local yellow pages can be helpful. There are solar thermal pumps you can consider which begins to operate once the sun comes up and keeps on pumping till the sun sets and this works on the heat difference and uses no external external power. These can be be very economical and trouble free.

Very thankful to CR4 through which we received the Solar Pump informastion from Mr. Krishnamoorty .

The information furnished is excellent one and the Solar Thermal Pump concept is new to me and quite educative one.

The solar thermal pump mentioned by a previous correspondent is quite usually referred to as a "hot air engine" or a Stirling Cycle engine and was first used as a water pumping device in the late 18th century (the devices are over 150 years old). I suggest that you "google" "hot air engine" or Stirling Engine for more details. The main limitation here though is that they are generally very big for a relatively low output, so you would usually be far better advised to seek a solar power/electric pump combination. Mono Pumps manufacture a solar solution that uses a small progressive cavity pump that provides a useful output and does not require a lot of space.
