MODEL MEANING
IS series single-stage end-suction (axial intake) centrifugal
pump is an energy-saving pump designed by teamwork in the
whole nation, it is improved on a basis on model BA, B and
other single-stage water centrifugal pump. The advantages: its
hydraulic capability is distributed reasonably, wide option for
user, conveniently check and repair, the efficiency and throw
is up to advanced international level. This pump is suitable
for industrial and city water supply, water drainage, and widely
used for agricultural irrigation, transportation pure water or
other liquids whihc physical and chemical nature is similar to
pure water, and the temperature should not be higher than 80 .

1. IS series single-stage end-suction centrifugal pump is
designed ac cording to the capability and size stipul ated i n the
international Standard ISO2858, it is composed of pump body,
pump cover, impeller, shaft, ring seal, sleeve and suspended
bearing units.
2. The pump body and pump cover in IS series are
separated from the back of impeller, that is to say in general,
back open structure, whose advantages: convenient overhau l,
when checking and repairing, the pump body intake pimp,
discharge pipe and motor need not to move, just disassemly
the middle connector of extended coupling to quit therotor
units for overhaul.
3. The pump shell (that is pump body and pump cover)
forms the workroom of pump. Impeller, shaft and rolling bearing are the rotors for the pump. Suspended bearing units
support the rotors in the pump. The rolling bearing stands the
radial load and axial force.
4. In order to balance the axial force of the pump, most
of the pumps are designed with sealing rings at the front and
back of impellers and a balance hole on the rear impeller cap
plate. The reverse of impeller is not designed with sealing rings
or balance holes if pump axial force is not powerful.
5. The axial sealing ring of the pump is composed of
packing gland, packing rings and packing to avoid air admission
or severe water leakage. For the impeller with balance hole,
the empty chamber with soft packing is straight through with
the impeller inlet. If the liquid in the impeller inlet is in vacuum state, the air will enter along the surface of muff easily.
Therefore , the packing chamber is fitted with packing ring,
which has the seal function when pressure water inside the
chamber is led to it through a small hole in the pump cover.
For the impeller without balance hole, the packing ring may
be neglected in virtue of no existence of air leakage beca use
the impelle r back hydraulic pressure is larger than atmosphere
one.
6. To avoid abrasion of shaft, the part where the shaft
runs through packing chamber is fitte d with protective muff.
O ring is fitted between muff and shaft to protect aga inst air
entering or water leaking along the matching surface.
7. The pump is connected to motor with extending flexible
coupling. The pump turns clockwise when you look from the
driving end.

PUMP ASSEMBLY AND DISASSEMBLY
Before assembly, first check if there is any defect with
the parts affecting the assembly and clean them.
1. Screw in the connecting bolts, screw corks on the corresponding parts in advance.
2. Place the O-seal rings, paper pads, felts etc. on the
corresponding parts in advance.
3. Put the sealing, packing, packing ring, packing gland
etc. in turn into the pump cover.
4. Mount the rolling bearing on the shaft, then mount it
into the suspended stand, put on the gland to press the rolling
bearing tightly and put the connecting bolt on the shaft.
5. Mount the muff on the shaft, then mount the pump
cover on the suspended stand, mount the impeller, thrus t cushion, impeller nut etc. on and tighten them, Finally mount the
assembly into the pump casing and tighten the connecting bolts
on both pump casing and cover.
During the above assembly process, special attention has
to be paid to some small parts, such as flat keys, oil baffle
disks, the O-seal rings inside of the muff of water baffle,
which are easily missed or mounted in a wrong order.
Carry out the reversed order to disassemble the pump.

PUMP INSTALLATION
The in stallation quality results in an important factor to the
pump's movement and duration, therefore installation and correction must be carefully carried out.
Installation and correction
1. Clear up grease and filth on the foundation and then place
it on the ground.
2. Check the foundation levelness with a leveler and it is
allowed to use a wedge iron fort leveling.
3. Pour cement into the foundation and foot bolt holes.
4. After the cement is dried, check if both foundation and
foot bolt holes are loose, then properly tighten the foot bolts and
recheck the levelness.
5. Clean up the foundation's support plane, the planes of pump
and motor feet and mount both pump and motor on the foundation.
6. Keep a certain space between the clutches, check if the
central lines of both pump and motor shafts are identical and, if
not, use a thin pad to adjust it.
The difference between the upper and lower, right and left of
the outer circle of the clutch has not to be over 0.1mm, the difference between the maximum and minimum spaces on one periphery
of the two clutches' end-face spaces has not to be over 0.3mm.

. Start
1. Before linking both pump and motor, make sure the
motor moves in the correct direction and the pump moves flexibly.
2. Close the gate valve on the vomit pipeline.
3. Prime water into the pump fully or use a vacuum pump
to lead water.
4. Turn on the power. When the pump reaches the normal
moving speed, gradually open the gate valve on the vomit
pipeline and adjust it to the desired working conditions. The
pump is not allowed to continually work over 3 minutes with
the gate valve closed.
. Stop
1. Gradually close the gate valve on the vomit pipeline
and cut off the power.
2. Drain out the water inside of the pump to prevent it
from getting cracked due to freezing when the ambient temperature is below 0 .
3. In case of a long time stop, disassemble the pump,
clean and lubricate it, the pack and store it.
. RUNNING
1. During start and running, pay attention to the meter's
reading, to the bearing to see if it is heated, to the packing to
see if it leaks, to both vibration and noise of the pump to see
if they are normal and take on-time process if not.
2. For the bearing temperature, the maximum of it should
not be over 80 and it should not be over the ambient one
by 40 .
3. The normal leak from the packing should be a little
and even.
4. Keep the bearing's oil level at the normal position,
without being too high or low, and supplement the lubricating
oil on time in case of being too low.
5. Replace the seal ring when the space between the impeller and it becomes bigger due to wear.
1

3
. Installation
1. Have the pump's installation height, the pipeline length
and diameter and the flowrate comply with the calculations and
try best to reduce unnecessary loss.
2. Use a bigger pipeline diameter for a distance transportation. The pump pipeline should have a s tand o f its o wn a nd
do not let the pipeline weight upon the pump to avoid it from
pressed damage.
3. Mount the check valve outside of the g ate v alve o n t he
drain-out pipeline if required to mount it.

Note:For instance, a 100m

m=10m diameter
when which is converted into 100 times that of the pipe's diameter. Suppose the flow is 8L/s,
looked into the above table, the loss of the straight pipe is 1.3m each 100m, then the one for
100m
m is 0.13m, that is, for a 100m
m foot valve with a flow 8L/s, its head low is 0.13m.
