Horizontal Multistage Ring Sectional Centrifugal Process Pump
D280-43X3 for Mining Sewage Water
Description
A centrifugal pump works by creating a centrifugal force to move
liquid through the pump, increasing the liquid’s pressure as it
moves from suction through the discharge end. A multi-stage
centrifugal pump contains two or more impellers in the same pump
unit. Ring section pumps, which are a type of multistage
centrifugal pump, have multiple stages arranged in tandem inside
their casings. As the liquid passes through each stage, the
pressure of the liquid increases. This is especially useful for
certain applications, including boiler feed systems, municipal fire
suppression (think high-rise building sprinklers, for example),
amine sour natural gas treatment systems, and so many others.
The D series Multistage Ring Section Centrifugal Process Pump is a configured, ring section, multistage pump specifically designed for high pressure feed service in long distance water tranferring applications. A Centrifugal Process pump is one whose function is part of the process. The pump doing this type of job will be directly responsible for maintaining the continuous operation of the process.
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 tranports 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 intellient plant monitoring and diagnostic system
to monitor the pump's performance.
