Structural Description of AFB Horizontal Corrosion-Resistant Chemical Pump

Structural Diagram of BF-Type Corrosion-Resistant Chemical Pump

Pump rotation direction: When viewed from the suction inlet toward the motor end, the pump rotates in a clockwise direction.

　　The pump and the motor are mounted on the same base via an elastic coupling.

　　The pump’s shaft seal assembly adopts a new structure featuring a secondary impeller for pressure reduction and a dual-face mechanical seal. The sealing chamber is filled with high-quality calcium-based grease and is equipped with an oil cup.

Application of AFB Horizontal Corrosion-Resistant Chemical Pumps

　　AFB-type chemical pumps are widely used in sectors such as chemical industry, petroleum, metallurgy, light industry, synthetic fibers, environmental protection, food, and pharmaceuticals. These products feature dual-face mechanical seals, which play a significant role in enhancing product quality, reducing leakage, preventing contamination, and improving the environment. They boast advantages including stable and reliable performance, excellent sealing capabilities, attractive design, and ease of operation and maintenance.

Installation and Removal of AFB Horizontal Corrosion-Resistant Chemical Pumps

　　1. Before installing the mechanical seal, check whether all components are damaged. If any component is damaged, it should be repaired or replaced.

　　2. Strictly inspect the friction surfaces of the rotating ring and the stationary ring; there must be absolutely no trace of even the slightest impact or scratch. Before assembly, apply a thin layer of clean machine oil to the end faces of both the rotating ring and the stationary ring.

　　3. During assembly, pay attention to eliminating deviations and properly adjusting the spring compression to ensure it is neither too loose nor too tight. When tightening the fastening screws, apply even pressure to avoid skewing, which could lead to sealing failure.

　　4. When disassembling, pay attention to the correct disassembly sequence of the pump.

Operating Instructions for AFB Horizontal Corrosion-Resistant Chemical Pump

　　Start:

　　1. Prepare the necessary wrenches and tools.

　　2. Check whether grease has been added to the oil cup of the sealing device.

　　3. Check whether the pump’s rotation direction is correct; reverse rotation is strictly prohibited. A wrong rotation direction can cause the impeller nut to loosen, allowing corrosive media to enter the shaft journal and induce corrosion, ultimately rendering the pump inoperable. It could also cause the impeller nut to fly off, leading to a serious accident. Before starting the pump, be sure to cover the coupling properly to ensure safe operation.

　　4. When the pump is installed at a position lower than the liquid level (in backflow conditions), before starting the pump, open the gate valve on the pipeline to ensure that the pump is completely filled with liquid. If the pump is installed at a position higher than the liquid level (in vacuum conditions), before starting the pump, you must prime the pump and bleed any air out of it, ensuring that both the pump itself and the suction pipeline are fully filled with liquid and all air is expelled from the pump.

　　5. After starting the motor, slowly open the discharge gate valve. Once the pump is running normally, gradually open the valve to the desired degree.

　　Stop:

　　1. Close the gate valve on the pressure pipeline.

　　2. Stop the motor.

　　3. Close the gate valve on the suction pipeline.

　　4. When the ambient temperature falls below the liquid’s freezing point, drain all the liquid remaining in the pump.

　　5. If the pump is to be left idle for an extended period, the corrosive media inside the pump should be drained completely and the pump should be thoroughly rinsed with clean water. After cleaning, the pump must be properly stored.

　　Operation:

　　1. The temperature rise of the pump and motor should be checked regularly, with particular attention paid to the bearing temperature rise. The bearing temperature must not exceed 73℃.

　　2. During operation, if you detect any noise or other abnormal sounds, immediately stop the machine for inspection and resume operation only after the fault has been rectified.

　　3. Pay attention to the oil cup of the sealing device—ensure it remains filled with oil and replenish it promptly to guarantee proper lubrication.

　　4. Mechanical seals should be used in clean media free of suspended particles. Therefore, special attention must be paid to cleaning the piping system when installing a new pipeline system.

Do you have centrifugal pumps in stock?

Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.

What information should I provide when requesting a quote?

Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.

If you are not sure, don't worry, our business managers will assist you in determining this.

What products do you mainly produce?

Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.

Could you help me with the selection?

Certainly! If the water pump model is not selected accurately, there will be big problems. If you choose a smaller one, it won't meet your needs; if you choose a larger one, it will waste electricity and fuel, increasing your costs.

Why is it so slow to get a price quote?

Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
