3. Scope of application
FSB fluoroplastic
alloy centrifugal pump (fluoroplastic chemical pump) is widely used in
petrochemical industry, acid and alkali production, non-ferrous metal
smelting, automobile manufacturing pickling process, rare earth
separation, pesticides, dyes, medicine, paper making, electroplating,
radio and other industries, and is suitable for transporting clear

4. Product Features
FSB type
fluoroplastic alloy centrifugal pump (fluoroplastic chemical pump) is
composed of pump body, impeller, pump cover, seal, support, pump shaft,
coupling, lifting bolt, nut, base plate, etc.
1. Pump body: one
steel flange ring embedded in the left and right connection departments
is molded into plastic alloy. It has the advantages of compact and
reasonable structure, strong corrosion resistance, tight and reliable
sealing function, stable operation, low noise, high mechanical strength,
no aging, no toxin decomposition, convenient maintenance, smooth flow
passage, high efficiency, energy conservation, etc.
2. A stainless steel (1Cr18Ni9Ti) pressed plastic alloy is embedded on the right side of the gland.
3.
Impeller: the shaft connection method is adopted. The metal shaft is
made of high-quality steel and then wrapped with fluoroplastic for high
temperature compression molding, so that the impeller and the metal
shaft are firmly integrated to ensure that the shaft root and the rear
of the impeller bear the torque force when rotating, so that the flow
passage part of the medium is plastic alloy.
4. Mechanical seal:
WB2 type, ST type adjustable single end mechanical seal technology
without cooling water is adopted, which is made of silicon carbide,
high-purity alumina ceramics, filled with tetrafluoro, graphite and
other materials.

Note: 1. If the parameters
are different from those in the table during the model selection
process, our factory can improve the model selection through technology.
7. Installation method
(1)
The pump shall be installed and fixed on a stable foundation. It is
better to lay a cushion between the base and the foundation. Ensure that
the pump will not affect the vibration of the pipeline when it is
started. The pump is not affected by other mechanical vibration.
(2)
When installing the pipeline, it shall be noted that the inlet and
outlet pipelines of the pump shall not exert force on the pump and shall
be equipped with corresponding supports.
(3) Valves shall be
installed on the inlet and outlet pipelines of the pump when the pump is
installed under the condition of reverse flow, and it is better to
install pipeline compensator. When the pump is under suction working
condition, it is required to install valves at the inlet and outlet of
the pump.
(4) Sufficient maintenance space shall be reserved for
the pump during installation to facilitate equipment maintenance in the
later period.
8. Precautions
(1) It cannot be used when there is no liquid inside FSB fluoroplastic alloy centrifugal pump
(2)
When the filling seal of FSB fluoroplastic alloy centrifugal pump is
used and the filling box leaks, the leaking filler cannot be used again,
and it can only be used after all of them are replaced.
(3) If
FSB fluoroplastic alloy centrifugal pump uses mechanical seal, it is
necessary to ensure that there is enough liquid inside for mechanical
seal flushing.
9. Frequently Asked Questions
(1) If the water pump does not discharge water, it may be that there is air in the pump chamber.
(2)
Insufficient pump flow may be caused by partial blockage of pipes and
impeller of pump flow passage, insufficient valve opening, etc.
(3) Excessive pump power may be used beyond the rated flow.
(4) Noise and vibration may be caused by unstable pipeline support, gas mixed with liquid, bearing damage, etc.
10. Need to know
(1)
The FSB fluoroplastic alloy centrifugal pump is prohibited from idling,
and the minimum flow during pump operation is 35% of the design point.
(2) If cavitation occurs when the pump is running, it must be stopped within 1 minute.
(3)
The medium temperature change shall be controlled within 40 ℃.
Excessive temperature rise/drop may cause damage to pump parts.
(4)
If the power is cut off suddenly when the pump is running, the power
must be turned off immediately and the outlet valve must be closed.
(5)
The noise of the pump is ≤ 95dB. In case of vibration and noise, the
pump should be shut down for inspection and troubleshooting before
operation.
(6) Grease lubricated bearings shall be selected for the pump, and additional oil shall not be added to the bearing box.
