Dewatering Pump

Dewatering pumps are pumps that are specially designed to remove standing water by pumping it through the top of the pump. They are especially useful for water transfers, and handling dirty or sludgy water. In general, there are both powerful portable dewatering pumps as well as larger, much more powerful industrial duty pumps.

Smaller, portable pumps are commonly powered by 110 volt AC power, and are anywhere from one half of a horsepower up to three horsepower in strength. One H.P. pumps can move as much as 96 gallons of water per minute, and their small size and submergibility make them great for moving large quantities of water as well. Other pumps are designed specifically to move dirty water, and can pump as much as 50 gpm of water that contains sands, leaves, or other solids.

Many portable dewatering pumps feature standard connectors, and will quickly and easily connect to tough, PVC hoses with fire hose-style fittings. Some portable pumps are stackable, allowing them to be used in deeper standing water without a hose. In these cases, the output of one pump is fed directly into the input of another.

Industrial Dewatering Pumps

Large, more heavy-duty pumps can be used for many applications other than moving standing water. Some pumps are also adept at moving solids, for applications such as extracting sand for recycling construction materials. Pumps with semi-vortex impellers can also transfer solids and fibrous materials without the danger of clogging or breaking down.

MILA!!!!!!!!!!We miss you and many students think the miktsae in the photo is that there are two extra knees. Is that it?We started making baskets last week. Ms. Griffin and Sydney's mom are working on one for you. Don't worry, they won't finish it. They will teach you and let you do that. Casey wants you to know that it is 1:55 p.m.We were wondering and concluded that the reason you and your family are wearing socks is because the weather is getting colder.Our schedule has been crazy lately because of basket making, Dr. Seuss's birthday, and we are doing our mystery book report projects which are commercials. We are putting our heads inside a real t.v. with the parts taken out that Grace brought in. We are trying to get the other students in our class to read the book we are presenting. It is sooo fun. We have new student council members. They are Matt and Hailey and we started a green team and we now recycle and compost.We have to go now to the garden with Mr. See who you will meet when you get back!Love,Team Griffin
