Operations L

Good morning,

I want to initially buy 8 to 10 x Bilge Pumps for Fresh water that have the following Specs:

1. 12 volt but will consider 240 vt, the same as Australia
2. Pump water 2 meters high vertically
3. Pump around 60 liters a minute (1000 Gal/Hr / 4000 Ltr/Hr)
4. I must be able to reduce the flow rate using my inline flow controllers.  I sometimes reduce the flow rate down to as little as 1 to 2 liters per min ??pumps must be able to handle flow rate reductions without damaging pump
5. Prefer a power cord to be at least 1.5 meters if possible. Pump will be submerged just over 1 meter
6. Pumps must be able to pump continuously for up to five (5) hours at least once a day.
7. Handle Water temperature up to 30 or 40 degrees Celsius
These pumps sit at the bottom of the 1.25 meter Blue water tank.  Water is pumped 2 meters vertically and into a 60 cm Cooling Tower for a Still which produces Alcohol Vapour, where the cooling converts the vapour back into liquid.  The water then flows back into the original water tank, creating a water recycling system.
I also want 2 x Bilge pump that can move 1,000 hr in short bursts of say 1 to 2 hours at a time.  This pump will need to:

1. Pump 2 meters high out of one tank; then pump the water through a pipe (25mm) 15 to 20 meters level and then pump the water another 2 meters high into the receiving tank.
2. 12vt or 240vt
3. Low watt usage ??less than 1 Kwt per hour
4. All water is cold

I would like to receive your recommendations for the correct Bilge type pump to use as soon as possible as I want to place an order immediately if your pumps meet my specs.

Thank you,

Philip B. Northam
