QED Environmental Systems autopump can be used in landfills

Q.E.D. Environmental Systems Inc., a subsidiary of Minneapolis-based Graco Inc. headquartered in Dexter, Michigan, announces its new Autopump Ultra 4.5 for landfills, featuring technology designed to ease wear, cleaning and maintenance.

The pump features an increased clearance between the float and discharge tube—three times the clearance of the previous version—as well as increased clearance between the float and outercasing. This is designed for allowing more high solids and precipitate to be pumped without the pump stalling.

Other elements of the Autopump Ultra 4.5 include the non-stick finish on the float and a polished discharge tube designed to help slow the buildup that can cause pumps to stall or fail. All metal parts are made from 316 stainless steel. In addition, the float ends on the pump are made from engineered plastics for easy cleaning. These plastics are also designed to cause less friction and wear on the discharge tube.

The Autopump Ultra 4.5 with a 4.5 inch diameter is larger than previous products produced by QED; the increased size does not increase the total flow rate per minute, but does increase the volume pumped per stroke. This size is designed to allow the pump to achieve the same flow rates with fewer cycles, reducing wear to components inside the pump and extending its useful life, ultimately reducing maintenance and replacement costs.
