Product Overview

The AZ-type slurry pump is a new type of corrosion-resistant, energy-efficient pulp and slurry pump. Based on practical applications, it features high efficiency, virtually no or minimal leakage, excellent anti-clogging performance, smooth operation, high reliability, and a compact structure. As a manufacturer of pulp and chemical slurry pumps, Zhonglian Pump Industry adheres to the AP610 (10th Edition) – VDMA24297 (heavy-duty) standards, as well as the DN24256, |S02858, and GB5662-85 standards in its product design. This pump represents an upgraded version of slurry pumps such as TWZ and ZBJ.

 AZ-type slurry pump

The AZ-type corrosion-resistant slurry pump is suitable for conveying media that are low- or high-temperature, neutral or corrosive, clean or containing solid particles, toxic, and flammable or explosive. It is primarily used in industries such as chemical engineering, petrochemicals, steel plants, power plants, papermaking, pulp production, pharmaceuticals, food processing, and sugar manufacturing.

Installation and Operation Instructions for AZ-Type Corrosion-Resistant Pulp Slurry Pumps for Chemical Applications

I. Installation

1. Before installation and use, please read the “Installation, Use, and Maintenance Manual” carefully.

2. The pipeline weight must be supported separately; the pump must not bear the weight of the pipeline or any other torsional forces.

3.46# The lubricant level should be maintained close to the two oil-level lines on the oil window. The lubricant needs to be replaced every 1,500 operating hours.

4. Newly installed reforming pipelines and storage tanks should be thoroughly flushed to prevent solid particles from entering the mechanical seals, which could compromise sealing performance and reduce the seals’ service life.

II. Starting and Stopping

1. Preparations Before Starting

a. Use your hand to rotate the fan blades; the impeller should exhibit no signs of jamming or rubbing and should turn smoothly.

b. Open the inlet valve, close the outlet valve, and bleed the air from the pump to ensure it is completely filled with liquid.

c. Manually turn the pump to allow lubricant to enter the mechanical seal faces;

d. Jog the motor to confirm that the rotation direction is correct.

2. Starting and Operation

a. Fully open the inlet valve and close the outlet pipeline valve.

b. Turn on the power supply. Once the pump reaches its normal speed, gradually open the valve on the discharge pipeline and adjust it to the desired operating conditions.

c. Pay close attention to instrument readings and check for shaft seal leakage. Under normal conditions, mechanical seal leakage should be less than 3 drops per minute. Also, ensure that the temperature rise at the motor bearings does not exceed 70°C. If any abnormality is detected, immediately stop the machine and investigate the cause.

3. Parking

a. Gradually close the valve on the discharge pipeline and disconnect the power supply;

b. Close the inlet valve;

c. If the ambient temperature falls below 0°C, the liquid inside the pump should be drained completely to prevent the pump from freezing and cracking.

d. If the pump is to be idle for an extended period, it should be disassembled, cleaned, and properly packaged for storage.

III. Pump Maintenance and Servicing

1. Operation, Maintenance, and Servicing

a. The inlet pipeline must be highly sealed and free of leaks—no water or air leakage allowed.

b. Pump operation under cavitation conditions for extended periods is prohibited;

c. It is prohibited for the motor to operate under overcurrent conditions for an extended period when the pump is running at high flow rates.

d. Regularly check the motor current value during pump operation and strive to keep the pump operating within its designed performance range.

e. The pump should be monitored by a dedicated person during operation to prevent accidents.

f. The bearings of the pump should be lubricated every 500 operating hours;

g. After the pump has been in long-term operation, if mechanical wear causes increased noise and vibration in the unit, the pump should be stopped for inspection. If necessary, worn parts and bearings can be replaced. The typical overhaul period for the unit is one year.

h. If the unit encounters a malfunction during operation, you can troubleshoot it according to the methods provided in the table below. However, if you are unable to resolve the issue, do not disassemble the unit at random. Please contact our company’s maintenance department or an authorized service center promptly.

2. Mechanical Seal Maintenance and Servicing

a. The lubrication for mechanical seals shall be clean and free of solid particles.

b. Mechanical seals are strictly prohibited from operating under dry-grinding conditions.

c. Before starting, rotate the pump (or motor) several times to prevent sudden start-up from causing the sealing ring to break or get damaged.

Q

What is your typical delivery time?

A

Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。

Q

Do you have centrifugal pumps in stock?

A

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.

Q

What information should I provide when requesting a quote?

A

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.

Q

What products do you mainly produce?

A

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.

Q

Could you help me with the selection?

A

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.

Q

Why is it so slow to get a price quote?

A

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.
