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.
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.
High-efficiency hydraulics optimized by computational fluid dynamics calculations reduce lifecycle costs and energy usage.
Establish preventative maintenance schedules by pairing optional sensors for pressure, temperature and vibration to an intelligent plant monitoring and diagnostic system.
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.
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.
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).
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.
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.
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.
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.
e-MPA, e-MPR and e-MPV pumps have suction side plain bearings which are lubricated by the liquid being pumped.
