Product Description
Model Code Explanation
Product Introduction
The FY stainless steel vertical chemical sump pump is a newly designed pump based on traditional sump pumps and integrated with advanced technologies from similar products of Sulzer (Switzerland). Through structural optimization, the pump eliminates the mechanical seal commonly used in other vertical sump pumps and adopts a uniquely designed impeller, achieving high efficiency, energy savings, zero leakage, and long service life. It is widely used in industries such as petroleum, chemical processing, pharmaceuticals, paper making, metallurgy, and wastewater treatment.
1. The FY stainless steel chemical sump pump features a vertical structure with an aesthetically pleasing appearance. It is installed directly on the storage container of the conveyed medium, requiring no extra floor space and reducing infrastructure investment.
2. The removal of the mechanical seal eliminates the frequent maintenance required due to seal wear, significantly reducing operating costs and improving work efficiency.
3. The pump adopts a unique centrifugal double-balanced impeller for conveying clean liquids without solid particles. It operates with extremely low noise and vibration while providing high efficiency. When equipped with an open double-balanced impeller, it is suitable for conveying unclean liquids containing solid particles or short fibers, ensuring smooth operation without clogging.
Operating Conditions
1. The allowable temperature of the conveyed medium for the FY stainless steel chemical sump pump is -20 °C to 140 °C.
2. For pumps made of cast iron, the applicable medium pH range is 5–9.
3. For pumps equipped with an open impeller, the diameter of solid particles in the conveyed liquid should not exceed 30% of the pump inlet diameter.

Operating Notes
Disassembly and Assembly
1. To replace or inspect the impeller, close the discharge valve, remove the flange bolts and base plate bolts, and lift the pump out of the container using a hoist.
2. Place the base plate vertically on a fixed support, remove all bolts from the pump body, take off the pump cover and impeller nut, and tap the pump body lightly with a hammer to remove the impeller.
3. To replace the sleeve bearing, keep the base plate fixed, remove the motor and corresponding support, then remove the pump coupling, gland, and round nut to extract the shaft sleeve assembly.
4. Assemble in the reverse order of disassembly, ensuring proper alignment and concentricity of all components on the shaft.
Installation, Operation, and Maintenance
1. After assembling the FY stainless steel chemical sump pump, rotate the coupling by hand to check for smooth movement. Ensure no metal friction noise is present and all nuts are tightened securely.
2. Check the alignment between the pump shaft and motor shaft. The radial deviation of the upper and lower coupling outer circles must not exceed 0.1 mm, and the coupling end-face gap should be kept between 1 mm and 2.5 mm.
3. The distance from the pump inlet to the bottom of the container should be 2–3 times the pump inlet diameter. The distance between the pump body and the container wall should be greater than 2.5 times the inlet diameter.
4. The discharge pipeline must be supported by a separate bracket; its weight must not be borne by the pump.
5. Check the motor’s rotation direction to ensure that the pump rotates in the indicated direction.
6. Close the discharge valve on the pipeline and connect the cooling water line.
7. Start the motor and slowly open the discharge valve to the desired position to begin normal operation.
8. Regularly inspect the pump and motor conditions. Bearing temperature rise should not exceed 75 °C, and the bearing housing should contain sufficient grease.
