Parking lot drainage sump pump

Postby lwparchive » Mon Nov 05, 2012 5:10 pm

We have a small sump area that displaces all the rain water off our back parking lot. We now have a 115-volt 1/2 HP and a 2" discharge sump pump. Our problem is when it rains harder than usual this pump cannot keep up with the volume and the water comes into the building. We are looking for a 3/4 or 1 hp pump at 115 volt with a 2" discharge. We believe that with a larger pump we will be able to displace more of the water quicker and keep it from coming into the building. Is there anything in your inventory that might help us with our situation. Seems as thought having the 2" discharge is the problem. Most pump motors in this range are 1.5" discharge.

You might want to consider the Gould's WE series pumps. ... ath=1_3_93

We have a community that has septic drainage issues. Gravity is not working and the home owners need a good moderate priced water pump that will pump the water into the drain field. Kindly email us the part no. Thanks--JP
