Performance plus efficiency in a versatile ring section multistage pump

Safe. Strong. Cost-effective. e-MP multistage pumps get the job done in nearly any high-pressure application – with lower lifecycle costs, lower energy usage, long-term dependability and the versatility to handle a wide range of applications. Available in horizontal or vertical configurations and with robust material options and smart design features, e-MP pumps can handle moving a variety of fluids across a wide range of applications including pressure boosting, boiler feed, filtration, fluid transport, dewatering and more. Now assembled in the USA, e-MP multistage pumps are proof Xylem puts industrial-strength thinking to work for the manufacturing, power generation, oil & gas, mining, commercial building, agricultural, water utilities and leisure industries.

Quick selection

e-MP multistage pumps come in so many sizes, models and materials you can perfectly configure them to your system requirements. And selecting the right model and accessories is simple with our Intellitronic X Selection software. Just select the vertical or horizontal orientation, configure the casings, hydraulics and seals based on your application. We’ll assemble your pump and get it on its way.

Benefits

Improved Design

Versatile mechanical configuration and a redesigned first stage suction impeller make it easy to integrate into high-pressure applications, with the high-suction capabilities needed for rigorous hot water or condensate demands.

Safe Operation

Protect your people and reduce downtime with built-in safeguards, such as a large self-cleaning seal chamber for solids handling and a variety of variable frequency drive options.

Energy Savings 

High-efficiency hydraulics optimized by computational fluid dynamics calculations reduce lifecycle costs and energy usage.

Optimized MTBRs 

Establish preventative maintenance schedules by pairing optional sensors for pressure, temperature and vibration to an intelligent plant monitoring and diagnostic system.

Reduced Wear

Elastically-supported plain bearings made from tungsten carbide resist extreme vibrations and shocks. A balancing drum reduces axial thrust of bearings and loads on mechanical seal for more efficient operation.

Easy Maintenance

Drive side bearing, mechanical seal and balancing drum sub-assembly are all easily accessible without removing pump from the piping system, and use common parts across the range to simplify spare parts management.

 

Features

Suction Impeller

The first stage suction impeller that is engineered with a wider inlet diameter reducing of the velocity of the liquid for reduced friction and increased suction capability (or low NPSH, as required).

U-turn Channels

The salient rounded edges of the U-turn channels in each stage casing ensure a balanced velocity allocation of the liquid being pumped, reducing losses and increasing hydraulic efficiency from one stage to the next.

Balancing System

The balancing system consists of the balancing bushing, installed in the discharge casing, and the balancing drum, assembled on the shaft. The system uses the force of the liquid being pumped to reduce load on mechanical seal and wear on the bearings. The complete system can be disassembled for maintenance without removing pump from its piping.

Seal Housing

Large, self-cleaning seal housing transports particles outwards along the conical-shaped chamber to the relief piping, then back from sealing chamber to suction side to ensure seal longevity.

Sensor Interfaces

Two standard pressure sensors, one at suction and one at discharge nozzle, measure inlet and outlet pressure, while optional sensors, one for horizontal, one for vertical, at the bearing frame can measure vibrations and bearing temperature. The sensors can be connected to any intelligent plant monitoring and diagnostic system to monitor the pump’s performance.

Plain Bearing

e-MPA, e-MPR and e-MPV pumps have suction side plain bearings which are lubricated by the liquid being pumped.
