Hello mechmerizer

  1. You haven't stated the size of the intended motor/pump assembly.
  2. You haven't advised the "head" required of the pump, or the intended pumped pressure.
  3. You haven't advised quantity of fluid pumped per hour/day/week etc.
  4. You would need to advise on whether the motor/pump was to operate only daylight sunny hours, or 24/7.
  5. You would need to advise location of the pump, so weather pattern, and actual sunshine hours at what latitude you are installing the motor/pump.
  6. You would need to advise what fluid you intend pumping: Fresh water/Sea water/Petrol/Avgas/oil/air/other....
  7. There are other important unknown factors, and you need to advise of these....

Then you may receive a proper answer.

Reply here, with

Kind Regards....

oh yeah.. right.. thought i'll see if its possible first and then get down to the details.. head required is very low and normal may be say 3-5 m head 1 m suction.. so planning to use a 0.5HP or 1HP selfpriming pump.. want it compatible with fresh and saline waters.. water is not pressurised.. the pump is ok, i want a solar panel and a way to get the voltage right may be 200-240 V and 2-3 amps.. any more details?? thats all about the electrical part.. the pump part is just fine.. Quantity of water may be not taken into consideration for now.. because it cannot be pre determined in the case i work for... and it may not work in pure daylight so i may need to put it to a battery first and then take it from there to the motor..

There are currently solar powered water pumps that are used to circulate water through a solar water heating system. In those systems all the water is at city water pressure. The pump is only needed to keep the cold water going to the roof when the sun is shining. Sorry I do not have a name, or web site for you.

i'm working in the case of non mechanized fishing boats where water floods in when the net is drawn back.. currently men pour it out in buckets and i'm planning for a pump.. lower cost too.. so the boat acts like a sump.. it shouldn't be more than a 1/2 m deep and more than 5000 lts at a time...

This sort of pump can be purchased over-the-counter at agricultural equipment dealers in the UK for £50-150GBP. Of course, being 240VAC here, it would need a DC-AC inverter between it and the solar panels/battery storage. Inverters can be purchased over-the-counter at larger caravan/trailer equipment outlets for about the same sort of values. On-line suppliers of these items are also available.

I suggest that you google "bilge pumps".

There are many options that run on 12V solar cells, or directly from battery that are simple to install and can cope with constant duty or being switched on and off.

Failing that, instead of buckets, what about a good hand powered pump that can work at night (Whenever there is a person available) and could have its suction right down low in the bilges where the buckets would be very difficult to use.

ya thanks but i'm a manufacturer of commercial water lifting pumps for house hold and agricultural usage.. i'm looking for technologies to modify my product a bit more to facilitate versatility.. would it be very space consuming to use solar cells, put them in batteries, step them up and then run the motor???

Why not size the motor to the solar panel(s)? In another thread we discussed a wave powered device to generate electricity.

What about a float extending from the side, or front of the boat past a fulcrum to a diaphragm pump in the bottom of the pump? The rocking action of the boat would suck the water up from the bottom, and over the side.

Re: solar powered motor/pump

This is the pump I was thinking of.

400H SERIES - Horizontal Handle
connects to 1" I.D. Hose

Price: from 55.95 CAD
($55.95 USD)

Item 1 on Order Form

Item 1 on Price List

SPECIFICATIONS:
Capacity: 38 litres per minute (8 G.P.M..) Weight : .57 kilograms (1.25 lbs.)
Size: 25 cm. long (10") 12.5 cm. wide (5")- 10 cm. high (4")

MATERIALS:

  • body made of injection molded DuPont Delrin
  • handle made of anodized aluminum
  • diaphragm and valves made of Buna-N, reinforced with Dacron. (optional materials listed below)
  • fasteners made of stainless steel

OPTIONS:

  • Item 2 - male garden hose thread on inlet and outlet flanges (also known as Model 400HG)
  • Item 4 - Vertical handle
  • Item 5 - aluminum clamp ring - valve stops
  • diaphragm and valves made of Neoprene, EPDM or Viton for chemical compatibility. Neoprene is also recommended for prolonged sun exposure

If the pump handle was the optional vertical one, and attached to an arm over the side that was floating on the top of the water, the wave action should cause the pump to suck the water from the bilge, over the side. It is also available in larger sizes.

Hello Mechmerizer,

You say your a manufacturer of commercial water lifting pumps.

DaS Energy Pty Ltd took the 18th centruary Ammonia motor (Solar Powered) and converted it from piston to turbine.

This we call the DaS Valve an essential in our other products replacing the piston combustion engine and the steam turbine.

In order to use less heat for greater pressure we now use Co2 in place of Ammonia.

This positive action water pump is only limited by the strength of construction material and available heat.

80% efficiency is acheived by using only a float and one way valves, plus a hydro turbine.

To date the pump and engine manufacturers we have approached have preffered to see us dead than for our invention to ever get on the market.

We know of no other in the world who can use air temperature from -20 degrees celsius to +75c (optimum) and above to rotatate a shaft.

For pressure versus temperature of Co2 please select from any web site.

Our current machinary operates at two different temperatures in the one device, low temperature is +31c 74 bar and high temperature +75c 10,000 bar.

Reduction in temperature correspondingly reduces pressure.

Working ratio is one to one, one litre recyling Co2 delivers one litre of water.

Recycling the water as well as the Co2 makes a very simple heat activated motor.

If your brave enough to put that on the market we will wave Patent and Intelletual Propperty rights.

Cheers

Peter

A solar pump to spray water up into the air to help keep the oxygen levels high in fish pond might make you some money too. Fish grow faster in water with high oxygen levels.

I don't know if they grow faster, but they grow longer!

Is that considered doping in the fish racing community?

Well they monitor large ponds for oxygen level if they are do not have some system to maintain O2 levels and feed the fish less so they food is not wasted and there is not a build up of uneaten food adding to the toxic soup of waste on the bootom of ponds.

Fish waste must be pumped out or the pond drained regularly to pervent disease and fish kills in the pond.

Ummm (gosh, I hate to explain these things...) "make the fish grow faster" = "fish racing"; I'd say you had to be there, but you were, doggone it!

How about a solar water pump for emgerency use to make fresh water. A light and cheap system that could make 2 or 3 gallons a day in an emergency. Enough to keep a few people alive till rescued.

the matter is to pump out water which accumulated during fishing.. fresh water making is not the problem around here..
