SFY Series Vertical Chemical Centrifugal Pump

SFY series liquid pump is a vertical single-stage single-suction pump, used for conveying solid particles and not easy to crystallize the corrosive liquid. The temperature of the transported medium is -20 degrees Celsius -150 degrees Celsius. Special needs can be -50 ℃-150 ℃. The pump has the characteristics of small footprint, reliable use, convenient maintenance, and strong corrosion resistance. At the same time, it cancels the mechanical seal commonly used in other submerged pumps, and selects a unique structure of the impeller, so that the pump has no leakage and long life. It is widely used in petroleum, chemical, pharmaceutical, papermaking, metallurgy, sewage treatment and other industries.

Model meaning

Product Structure

The submerged pump is mainly composed of pump body, pump cover, impeller, shaft, elastic coupling, pipe flange, guide bearing, intermediate connecting pipe, liquid discharge pipe, bearing frame, base plate, motor frame and other parts.
The suction inlet of the vertical chemical centrifugal pump is along the axis direction, and the outlet is parallel to the axis.
The ss chemical pump turns clockwise from the suction inlet to the motor end.
The vertical motor of the pump is fixed on the motor seat by bolts, and directly drives with the pump through an elastic coupling. The pump body, the intermediate connecting pipe, the pump frame, the liquid discharge pipe and the pipe flange are connected by bolts and fixed on the bottom plate. The whole pump is installed on the container through the bottom plate. Other main parts of the pump, such as motor base, pump frame and chassis, except for liquid contact parts, are made of cast iron.
The axial force and radial force of Shanglishi Vertical Chemical Centrifugal Pump (including the water pressure generated during the operation of the pump, the weight of the impeller and the rotor, etc.) are borne by the one-way thrust ball bearings, single-row radial ball bearings and sliding guide shafts installed in the bearing box. In order to ensure the safe and normal operation of the pump, the bearings are lubricated with butter, and the liquid conveyed by the guide bearings is lubricated. Therefore, the liquid level must be higher than the center line of the impeller when working.
The vertical chemical centrifugal pump adopts soft packing seal as the basic sealing form and uses butter at the packing ring to ensure the normal operation of the packing and prolong the service life. Appropriate amount of molybdenum disulfide should be added to the butter.
In addition, the corrosion-resistant centrifugal pump series under liquid is divided into the structure of the intermediate guide bearing and the structure without the intermediate guide bearing due to the different length of the length L extending into the container.

Differences Between Vertical and Horizontal Chemical Centrifugal Pumps

Below is a detailed comparison of vertical and horizontal centrifugal pumps in chemical applications, based on functionality, design, and operational suitability:

1. Shaft Orientation and Space Requirements

Vertical Pumps: The shaft and motor are aligned vertically, allowing the pump to occupy a smaller footprint. This makes them ideal for chemical plants with limited floor space or applications requiring submerged installation (e.g., sumps, tanks).
Horizontal Pumps: The shaft is positioned horizontally, requiring more floor space. However, this design simplifies access to internal components during maintenance.

2. Installation and Maintenance

Vertical Pumps: Often used in deep-well or sump applications where fluid must be lifted vertically.
Maintenance can be more complex due to vertical alignment, especially for submerged parts like bearings and seals.
Horizontal Pumps: Easier to install and maintain because the horizontal design provides direct access to components like the impeller, shaft sleeve, and casing wear ring.
Commonly used in systems where the pump is located above ground, such as pipeline transfers or booster stations.

3. Fluid Handling and Application Context

Vertical Pumps:
Suitable for handling fluids with suspended solids, corrosive chemicals, or volatile liquids (e.g., acids, solvents) due to their ability to submerge and minimize leakage risks .
Often used in chemical processing for tank recirculation, wastewater drainage, or deep-well extraction .
Horizontal Pumps:
Better suited for high-flow, low-pressure applications, such as transferring large volumes of non-abrasive chemicals between storage tanks or reactors .
Nozzle configurations (e.g., side suction/top discharge) allow flexible piping layouts in horizontal systems .

4. Efficiency and Operational Factors

Vertical Pumps:
May require higher Net Positive Suction Head (NPSH) to prevent cavitation, especially when lifting fluid from deep sources .
Typically less energy-efficient for low-lift, high-flow scenarios compared to horizontal pumps.
Horizontal Pumps:
Generally more energy-efficient in high-flow applications due to streamlined hydraulic design and reduced friction losses .
Lower NPSH requirements make them suitable for systems with limited suction pressure.

5. Noise and Coupling Capability

Vertical Pumps:
Generate less noise due to vertical alignment and submerged operation, which dampens vibrations.
Horizontal Pumps:
May produce more noise, especially in high-speed configurations. However, they offer better coupling flexibility with motors and gearboxes.
