Multi-Stage Pumps

e-MP Multistage Ring Section Pump

The highly versatile casted multistage pump

Finally, there’s a robust and reliable pumping system for virtually any high pressure application. The GWT e-MP multistage ring section pump combines Xylem’s century of experience, knowhow and expertise to create a powerful and efficient solution for customers in industry, public utilities, agriculture and building services. Designed to be configured in a multitude of ways, the GWT e-MP has applications limited only by your imagination.

Benefits

Improved Design

Simply and cost-effectively integrate the e-MP into nearly any high pressure application, thanks to its versatile mechanical configuration and its first stage suction impeller. This newly redesigned impeller provides high suction capabilities needed to meet the rigorous demands of hot water or condensate pumping applications.

Safe operation

Protect your people and reduce downtime with the e-MP. It incorporates an assortment of built-in safeguards. Plus, you can further control and monitor safety by connecting the pump to a variety of variable frequency drive options.

Energy savings

Leave a greener footprint. The high efficiency hydraulics of the e-MP were optimized by computational fluid dynamics calculations and they reduce both life cycle costs and energy demand.

Optimized MTBRs

With the help of optional sensor interfaces on the e-MP, pressure, temperature and vibration sensors can be installed. A preventative maintenance schedule for the pump can be projected in advance, by connecting them to an intelligent plant monitoring and diagnostic system.

Reduced wear

The newly designed plain bearing in the suction housing is made of tungsten carbide and is elastically supported to resist extreme vibrations and shocks. A balancing drum reduces the axial thrust of the bearings and the load on the mechanical seal. The ultimate result is a more efficient, more effective operation.

Easy maintenance

The bearing at the drive side, the mechanical seal and the balancing drum sub-assembly are all easily accessible without having to remove the pump from the piping system. The pump’s configuration minimizes the number of parts needed to cover the complete performance range, which simplifies assembly and streamlines spare parts management.
