QED Environmental Systems Launches Autopump Ultra 4.5 for Landfill Applications

Q.E.D Environmental Systems, Inc.

Q.E.D. Environmental Systems announces its new Autopump Ultra 4.5 for landfills, featuring technology that eases wear, cleaning and maintenance.

The Autopump Ultra 4.5 is unlike any other pump available for its application. The most unique feature of the pump is its 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 outer casing. This cost-saving improvement allows for more high solids and precipitate to be pumped without the pump stalling, extending usage between cleaning and maintenance breaks.

Other thoughtful design elements of the Autopump Ultra 4.5 include the proprietary non-stick finish on the float and a polished discharge tube, which helps to slow the buildup that can cause pumps to stall or fail. All metal parts are made from 316 stainless steel, which has superior corrosion resistance and can better withstand attacks from harsh landfill leachate than 303 or 304 stainless steel. In addition, the float ends on the pump are made from engineered plastics for easy cleaning. These plastics also 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 allows 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.
