Commercial and industrial plumbing jobs require heavier-duty equipment. That doesn’t mean that equipment can’t also be energy and space efficient, though. Bell & Gossett, a Xylem brand, recently launched the Series e-82 Twin Vertical In-Line Centrifugal Pump, expanding its offering of energy-efficient pumping solutions. The Series e-82 line delivers about 40% space savings for parallel pumping installations and provides energy-efficient pumping for commercial HVAC and plumbing applications, making it ideal for parallel staging or back-up capacity in hydronic heating and cooling systems, light industrial processes, general service, pressure boosting and OEM applications.

“The e-82 twin pump offers parallel pumping without larger headers and additional isolation valves,” says Alan Jones, Bell & Gossett director, global residential and CBS/HVAC Americas product management. “Its space-saving design makes it ideal for a wide range of applications.”

The Series e-82 pump has stainless impellers to improve sustainable hydraulic performance, resist chemicals and reduce corrosion. The pump’s built-in mechanical seal chamber and a flexible stainless steel braided hose ensure seal cooling and lubrication. A compact footprint also facilitates easy installation and maintenance, with a back pullout design allowing the removal of the impeller, seal and motor without disconnecting the piping system. The Series e-82 is also designed for easy retrofit installations with flange-to-flange compatibility to Bell & Gossett Series 80 legacy pumps.

The series provides a wide hydraulic range with 22 models (11 split-coupled and close-coupled models each) and features a changeover valve for the option to operate pumps separately or in parallel. In parallel mode, the pumps can handle flows up to 1,600 gpm with head up to 130 feet total dynamic head and 175 psi standard.

“The pump also features sensorless control and variable speed integrated drive options to maximize energy savings,” says Jones. Optional variable speed drives provide variable flow pumping for the broadest range of applications. The Integrated Technologic Sensorless Control drive combines the energy savings of variable flow with sensorless curve control to provide turn down at low flow, while eliminating the cost and time of using wired transducers and sensors. The Integrated Technologic drive is another variable speed option designed for building automation system control. It’s an energy-efficient and economical alternative for applications that don’t require sensorless control. A third is the Technologic Intelligent Pump Controller, which has a start-up genie, making it easy to commission and easy to integrate with any building management system. 847-966-3700; www.bellgossett.com
