This lightweight pump is ideal for environmental applications
Q.E.D. Environmental Systems
The SlimJim Electric Pump System (photo) is particularly well-suited for environmental-remediation sites and landfills. It requires no separate control panel and features built-in automatic on/off start and run-dry protection. It offers plug-in operation at 115- or 230-V single-phase power. With a 4.5-in. outer dia., the pump is compact and easy to handle and weighs only 22 lb. It is ideal for smaller-diameter risers, such as cleanouts, collapsed pipes or bent risers, says the manufacturer. The pump’s optional three-phase operation with control panels adds several benefits, including variable speed, programmable from a smart phone, and the ability to view and change pump data and parameters. With available flowrates of up to 30 gal/min, the SlimJim can be used in vertical or horizontal applications, and is suitable for the same applications as air-powered pumps, but operates at higher flowrates. The stainless- steel motor and pump casing and high-density polyethylene protective shroud resist corrosion. A chemical-resistant Teflon version is also available. — Q.E.D.

This intrinsically safe pump prevents fluids at the shaft seal
Paul Bungartz
The intrinsically safe MPCVAN pump (photo) is a dry-running magnetic-drive centrifugal pump that is suitable for fluids that are hot, abrasive and corrosive. The vertical pump is hermetically sealed, with a shaft seal concept based on the complete hydrodynamic relief of the shaft seal and bearing unit, says the manufacturer. The penetration of product fluid or vapors into the shaft seal area is prevented by impeller back vanes during operation, and a gas barrier during stand-still operation. — Paul Bungartz GmbH & Co.
