FYS and FY type corrosion-resistant vertical submerged pump is a single-stage single suction long shaft submerged pump. Its technical specifications adopt ISO9001 standard. It has the advantages of small volume, high efficiency, good energy saving effect and reliable operation. It is suitable for conveying corrosive medium without solid particles and abrasives.
1、FYS type fluoroplastic submerged pump, the main shaft is totally enclosed and plastic coated, the mechanical seal is ceramic and tetrafluoro graphite grinding, the pump body, impeller and back cover adopt the set mold, the impeller is left-hand thread rotation sealed on the pump shaft, the conveying medium does not contact with any metal.
2、The submerged part of the stainless steel submerged pump is made of stainless steel. Users should be careful when selecting materials. For example, chemical medium such us sulfuric acid and hydrochloric acid with corrosive effect on stainless steel,please consult us before use.
The working pressure of the pump is designed as 1.6Mpa.
Performance range of pump: flow is 1.6～1600m³ / h, head is 5 ～80m

When starting the FYS type corrosion-resistant plastic submerged pump, the liquid level must be higher than the center line of the impeller.
The materials contacted liquid by FYS and FY type corrosion-resistant submerged pump are as follows:
The corrosion resistant submerged pump is composed of six parts:
1、Pump body part: pump body and pump cover
2、Rotor part: shaft, impeller, upper shaft sleeve, lower shaft sleeve, coupling
3、Bearing part: centripetal thrust ball bearing and single row ball bearing are lubricated by grease or molybdenum disulfide.
4、Supporting part: motor pump, bearing body, intermediate connecting pipe and base plate.
5、Pipe fittings: outlet pipe, elbow pipe and suction pipe
6、Sealing part: Tetrafluoro graphite and acid resistant ceramic
The suction port of the pump is along the axis direction: the outlet is parallel to the axis. The running direction of the pump is indicated by the arrow mark.
The vertical motor of the pump is fastened on the motor frame by stud bolts and driven by elastic coupling. It is composed of pump body, intermediate connecting pipe, bearing body, liquid outlet pipe, pipe flange and bolt connection, which is fixed on the bottom plate. The whole pump is installed on the container through the bottom plate.
The axial force and radial force of the pump (Including the water pressure generated in operation and the weight of impeller rotor, etc. .) are all borne by the newly installed one-way thrust ball bearing, single row radial ball bearing, single row radial ball bearing and sliding guide bearing in the bearing body. In order to ensure the safe and normal operation of the pump,
the guide bearing is lubricated by the liquid delivered.
The impeller geometry of the corrosion-resistant submerged centrifugal pump series is also different due to different speed. Generally, closed and open impellers are used.
The corrosion resistant submerged pump series can be divided into the middle guide bearing structure and the structure without the middle guide bearing due to the different submerged depth.
Installation and use
1、Operate in the direction indicated by the arrow, and do not reverse the direction<Impeller will fall off if reverse>
2、Before installation, please rotate the coupling by hand to check whether the main shaft rotates normally, whether the pump shaft is concentric with the motor shaft, and whether the motor power and speed are consistent.
3、During installation, pay attention to whether the size of the base plate is consistent with the reserved material storage tank, and ensure the vertical installation, so that the distance between the lowest end of the suction port and the bottom of the material storage tank is about 20cm.
4、The outlet pipe of the pump shall be supported by another bracket, and its weight is not allowed to be added on the outlet pipe of the pump body, so as to avoid unexpected damage caused by overload at the outlet elbow.
5、When connecting the power supply, do not connect the wrong or lack of phase. Before starting, close the valve and pressure gauge on the outlet pipeline first. When starting, identify the electric phase turning direction, and operate as indicated by the arrow mark,do not reverse. After starting, open the pressure gauge, slowly open the outlet pipeline valve, and pay attention to the flow and head after normal operation.
6、When in use, the pump body shall be immersed in the liquid, and it shall not be operated without liquid. For pumps with intermediate guide bearing structure, the guide bearing shall be immersed in the liquid, otherwise, a proper amount of liquid shall be led out from the outlet pipeline, and the guide bearing shall be lubricated to prevent dry grinding damage.
7、When stop, first close the outlet valve, then stop the motor and close the pressure gauge.
Possible faults and troubleshooting
Precautions
1、When carrying and hoisting the pump, the lifting point shall be on the the motor or motor connecting frame, and the plastic pipe bracket shall not be used as the support point. The outlet pipe of the stainless steel pump shall be careful to avoid damage.
2、When the pump is running, observe the liquid level in the storage tank at any time, and it is strictly prohibited to operate without liquid.
3、After three months of use, the pump shall be inspected, and the lubricating grease shall be added in the bearing seat. If the parts are worn, they shall be replaced in time. In case of failure during operation, they shall be stopped for maintenance, and please contact the company.
4、After the pump is stopped, if it is not used for a long time, it shall be cleaned with water, properly maintained and inspected regularly.
