can you give me some information?
Little Giant makes a good, reliable, reasonably priced water pump. You can get them at Grainger, MSC and I'm sure many other places.
Water pumps come in all sizes from less than one gallon per hour to over 50,000 gallons per minute. They also produce pressures on the discharge from a few inches of water to thousands of pounds per square inch. They pump water with all kinds of contaminates and chemicals dissolved in the water. Finally they can have all kinds of service conditions from a few minutes at a time once a day to continuous operation. All of these factors enter into what you need to have a good quality pump.
