Not sure what you need send me a question and some details. Brian 1100 GPH pump This water pump is manufactured as a bilge pump for marine use. But as a basic water pump you can do many jobs with it. * MARINES BILGE PUMP * WATER FOUNTAIN PUMP * RV WATER PUMP * PORTABLE SHOWER PUMP * POND PUMP AND MORE. You will need a hose that is 3/4 ID (inside diameter) or 19 mm ID a float on/off switch is used in most marine( boat ) applications. not included. The instruction manual is written for marine usage. Installing a bilge pump etc. 4 1/4 long (11cm) x 2 1/4 (5.5 cm) wide 3 FOOT WIRES (92 CM) 12 VOLT DC 2.5 AMP quiet operation Blue top snaps on and off , the groves in the blue are a filter of sorts. If you were using it as a bilge pump you remove the blue section ,screw it down and snap the pump on. this test done on 750 gph pump. I will be keeping one for my personal use of course, so I ran some experiments on mine. as with all pumps the higher you go from the pump( known as head) the slower the pump pumps. 750 GPH at 0 head at 2 feet head I calculated 240 GPH at 4 feet head I calculated 180 GPH at 5 feet head I calculated 40 GPH between 5-6 feet it lost pressure and could not pump higher. I would call it 5 foot MAX head. Also reducing the diameter of the hose and any bends in the piping (90 % bends for example) will reduce the pressure which will reduce the GPH flow. Now I wanted to know what would happen using a solar panel rated at 18 volts and 1.3 amps( 20 watt panel from my store) It seems to be pumping at the same rates as using the 12 volt battery. I would have thought the pump would run faster and harder but my guess is the higher volts is being hampered by the lower amps of the panel. So my next experiment was to add a 10 watt panel ( 18 volt .6 amp) and a 20 watt panel together( wired in parallel) so now I had 18 volts at 2.3 amps. On a day with good but not clear skies I could hear the difference in the pump from the start, then the water flow was also faster and at 7 feet it still had pressure enough to pump but that was as tall as my hose could go. My next experiment was over many hours, I hooked up the 20 watt solar panel to the pump and stuck the hose back in the bucket. It has been running now for over 3 hours and seems to be fine with the additional volts. Now I am going to make a solar bird bath/fountain. Overall opinion it is a ridiculously powerful pump for it's size.
