Centrifugal pump series
FSB model FSB（D）Model
Application
The product is widely applicable to the following
fields: acid-washing and paint-spraying techniques in
auto manufacturing; transportation of electrolytes in
the non-ferrous metal metallurgy; chlorine water and
waste water treatment and technique process such
as acid-adding in ionic membrane sodium hudroxide
program.
Service temperature: -20℃~100℃.
The liquid-carrying parts of the FSB and FSB-D series
centrifugal pump are all made of fluoroplastic alloy. Their
structures are compact, operations easy, and prices
inexpensive. The pump casings, impellers, and
m e c h a n i c a l s e a l s , e t c . o f t h e m o d e l s a r e
interchangeable, and the models are warmly accepted
among industries such as pesticide, electronics, and
papermaking.

Notes on use of FYH fluoroplastic liquid in the pump
Notes on use
Disassembly and assembly:
1.If change or check the impeller, the outlet valve may be closed, and remove the flange connection bolt and the
pedestal connection bolt, then haul the pump out of the container with lifting equipment.
2.Remove all bolts of the pump, and take out the pump cover and the impeller nut, then tap the pump housing with
double hammer. This way the impeller is removed.
3.While changing the rolling bearings or the filler, the pedestal should not be moved, and remove the eletric motor and
its bracket, then remove the pump shaft coupling, the gland, the round nut, and take out the bearing body. While
changing the filler, first take out the filler gland, then take out the to-be-changed filler.
4.The sequence of disasembly is just the opposite to that of assembly, and the concentricity of the mating parts of the
shaft should be paid attention to.
Dos and don'ts：
1.There should be speical bracket for the liquid flowing-out duct of the pump, and it's forbidden to support it by the
pump.
2.After the assembling of the pump, rotate the shaft coupling to see whether it turns smoothly. Check whether there
are metallic grating noise and whether the bolts of all parts are tightened.
3.Check the concentricity of the pump shaft and the electric motor shaft. The left and right difference of the two shaft
coupling should not exceed 0.1mm, and the end clearance of the two shaft couplings should be kept at 1~2.5mm.
4.The distance from the pump's suction inlet to the bottom of the container should be 2 to 3 times the suction inlet
diameter, and the distance between the pump housing to the container wall should be bigger than 2.5 times of the
diameter.
5.Check the motor's direction of rotation and make it conform to the
required direction.
6.Close the gate valve and pressure gauge on the outlet duct.
7.Start the electric motor and open the pressure gauge, then slowly turn
the outlet duct gate valve to the required postion, and the normal
operation begins.
8.Regularly check the pump and the electric motor. The bearing's
temperature rise should be not more than 75 , and there should be
enough consistent grease in the bearing box.
