Product DescriptionSOW series horizontal single-stage split-casing
double-suction centrifugal pump is the latest generation of
split-casing double-suction pump,with notable features of perfect
spectrum, good model and outstanding performance, innovative and
reliable structure, easy maintenance and long life.Our current SOW
pump has 46 models, 390 basic specifications.By using the prime
impeller and modified impeller and cutting type, full of
broad-based spectrum, high efficiency and performance range in the
type spectrum, appropriately to meet the user needs at any point in
the work flow and head.By carefully manufactured and perfect
quality control, this product has reached domestic leading
level.This series of pumps meet ISO2548C, GB3216C, GB/T5657
standards.Double-suction impeller to reduce axial force to a
minimum; CAD hydraulic model to optimize the best design, good
performance; addition of a prototype impeller,it can also use
modified impeller to adapt to different working conditions, improve
efficiency . According to the forces condition, pump with double
volute form to reduce the radial force, to be small bearing force
and long life; easy installation, automatic calibration of the pump
cover; relative position of in and out of the pipeline of the motor
and the pump may change according to the user site requirements;
pump inlet without swirl, smooth running, low loss; through
precision casting, pump casing and impeller surface to be very
smoothly, with significant anti-cavitation performance and high
efficiency. Pump Speed298,372,490,585,740,990,1480 and
2950rpm;Motor Voltage380V/415V, 3.3KV, 6KV and
10KV;Caliber80-1600mm;(flange dimensions conform

pressure above 0.03Mpa (G)Structural DesignSingle-stage
double-suction volute axial centrifugal pump, horizontal
installation, driver (motor or engine) may be set on the left or
right side of the pump (ie, outlet-oriented, the driver is
counterclockwise in the left side, clockwise in the right
side).Detailed Photos Between-the-bearings: Split-case pumps
are what is referred to as a "between-the-bearings" pump. This
means that split-case pumps mount the impeller on a shaft that is
supported by bearings on both sides of the impeller.Double-suction
impeller: Split-case pumps are the only COMMON pump type with a
double suction impeller. A double-suction impeller imposes
dramatically fewer loads on the bearings than an impeller that only
draws in water from one side of the impeller
(single-suction). High-precision casting impeller can ensure
the performance, material in cast iron, stainless steel and
bronze. Packing seals have been the most widely used sealing
solution for many years. Packing seals use rope-like materials that
wrap around the shaft of a pump, filling in dead space and
minimizing fluid loss. Over time, however, fluid loss will increase
as the gland packing material begins to wear down and may impair
regular lubrication or reduce ease-of-replacement that is required
to function properly.Mechanical seals are preferred over
traditional packing seals in diverse applications during which
leakage problems should be avoided. Mechanical seals are more
durable than their predecessors and are designed to take much more
punishment. Basic mechanical seals use multiple sealing points to
nearly eliminate any leakage issues. Flexible couplingsUnlike
rigid couplings, flexible couplings can accommodate some movement
e.g. vibrations and thermal expansion without damage. This makes
them ideal for applications where there is a degree of unavoidable
misalignment between the drive and pump shafts. As they can absorb
vibrations well, they can also be used to reduce excessive
operating noise. With these benefits come a more complex, expensive
design. However, as flexible couplings protect the shaft and
bearings from damage and premature wear, there are maintenance
savings to be had in the long run.We use wear-resisting
disc coupling or pin coupling. Product
