Lightweight pumps ideal for small-diameter risers

September 13, 2018  By Ground Water Canada

Small-diameter SlimJim Electric Pump Systems, manufactured by manufactured by Q.E.D. Environmental Systems Inc., provide flows up to 30 gallons per minute in smaller risers without a control panel.

The pumps are particularly well suited for landfills and environmental remediation sites, the company said in a press release.

The pump’s optional three-phase operation with control panels adds several benefits, including variable speed and the ability to view and change pump data and parameters, the release said. This cost-effective pump lowers capital costs and eases maintenance, as proven in installations at over 500 landfills.


The SlimJim, which is part of the Torpedo pump range, requires no separate control panel and features built-in auto on/off start and run-dry protection. It provides plug-in operation at 115-volt or 230-volt single-phase power. With a 4.5-inch outer diameter, the pump is compact and easy to handle, and weighs only 22 pounds. It is ideal for smaller-diameter risers such as cleanouts, collapsed pipes or bent risers.

With available flow rates up to 30 gallons per minute, the pump can be used in vertical or horizontal applications. It is suitable for the same applications as air-powered pumps, but operates at higher flow rates.

In addition, there are no shroud wheels to break or hamper pump removal, and the stainless steel motor and pump casing, and high-density polyethylene protective shroud resist corrosion. A chemical-resistant Teflon version is also available.
