    Product description

    The standardized chemical process pump type CZ is a horizontal chemical centrifugal pump, single-stage and single-suction for oil use, whose dimensions and performance meet the standards DIN2456, ISO2858, GB5662-85, being a basic product of standardized chemical pumps. Product execution standards: API610 (tenth edition), VDMA24297 (light/medium). The performance range of the chemical process pump type CZ includes all the performance of the IH series of standardized chemical pumps, with efficiency and cavitation characteristics that exceed those of IH pumps, allowing for individual interchangeability with them. The characteristic curve is flat, suitable for selection when the flow varies relatively much. This chemical pump has a low cavitation value and high efficiency, maintaining these characteristics even under partial loads. It is suitable for transporting media at low or high temperatures, neutral or corrosive, clean or with solid particles, toxic and easily flammable or explosive. It is mainly used in chemical, petrochemical, steel, power generation, paper, food, sugar industries, among others.

    Scope of application of the standardized chemical process centrifugal pump type CZ

    The type CZ chemical process pump can transport various corrosive inorganic and organic acid solutions such as concentrated acid, nitric acid, hydrochloric acid, and phosphoric acid at different temperatures and concentrations; alkaline solutions such as sodium hydroxide and sodium carbonate at various temperatures and concentrations; various saline solutions; liquid petrochemical products, organic compounds, and other corrosive liquids. This pump is suitable for refineries, petrochemical industry, coal processing, cryogenic engineering, paper industry, sugar industry, water supply plants, seawater desalination plants, power plants, environmental protection projects, and the shipbuilding industry.

     

    Advantages of the product and structural characteristics of the standardized chemical process pump type CZ

    Product advantages:

    1. The pump and the motor of the chemical pump CZ are coaxially aligned, with good concentricity, low vibration, low noise, and stable operation.
    2. Selection of different casting materials and seals, can transport clean water, warm water, hot water, and various liquid media.
    3. Uses efficient and energy-saving Y2 and YX3 motors, equipped with high-quality national bearings, with high starting torque, high efficiency, low vibration, low noise, reliable operation, and long service life.
    4. Reasonable selection of materials for the mechanical seal, ensuring long-term operation without leaks, saving more than 50% in operating and management costs.
    5. By using mechanical seals and imported bearings, the reliability of the product is even greater.

     

    Structural characteristics:

    Standardized chemical process pump body: horizontal structure with an open rear door, the pump head is connected to the motor via a coupling, mounted on a base, the impeller is of the open rear type, with three bearings, external mechanical shaft seal, equipped with a cooling device, the oil level of the bearing body is observed through an oil sight glass; compact and reasonable structure. The pump has cast feet on the body, with a support structure on the base that can bear the load of the pipe and transmit it directly to the base, preventing the pump rotor from bending due to the load, thus ensuring a good service life of the support and the mechanical seal. For maintenance, it is not necessary to disconnect the pipes connected to the pump body, just loosen the bolts between the support and the body to separate and repair the impeller and the mechanical seal, which is simple and convenient.

    Impeller: closed, semi-open, and open impeller, the axial force of the chemical centrifugal pump CZ is mainly balanced by the rear blades or balance holes, the residual axial force is supported by the bearings.

    Pump cover: forms a sealing chamber with the packing, the standard size of the chamber can be equipped with various types of seals.

    Shaft seal: depending on the working conditions, can use packing seal, single face mechanical seal, double face mechanical seal, series mechanical seal, etc.

    Bearings: lubricated with fine oil, controlled by a fixed position oil cup, ensuring that the bearings work in good lubrication condition.

    Shaft: protected with a sleeve to avoid direct corrosion of the medium with the shaft, increasing the service life of the shaft.

    Rear drive design: allows maintenance without moving the inlet and outlet pipes of the pump, facilitating its use.

    FAQ

    Q

    What products do you mainly produce?

    A

    Zoomlion Pump Industry manufactures various large industrial centrifugal pumps. The main products include: self-balancing multistage pumps, multistage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condenser pumps, and more.

    Q

    Can you help me choose a model?

    A

    Of course! If the water pump model is not selected accurately, it can cause significant problems. After you take it back, it might be either too small to meet the usage requirements or too large, resulting in higher electricity and fuel costs, increasing the operating expenses.

    Q

    Why is the price quotation so slow?

    A

    Because centrifugal pumps are non-standard custom products with many models and a wide price range. Even for the same model, the price varies greatly depending on the materials and configurations used. Taking the most common 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 clearly confirm the relevant information to provide you with an accurate price. Normally, if you provide comprehensive information, we can quote within 5 minutes.

    Q

    What information should I provide when I need a quote?

    A

    Usually, if you want to get an accurate quote, it is recommended that you provide us with the following information: pump flow rate, head, on-site operating voltage, frequency, temperature of the conveyed liquid, pH value, solid particle content, on-site installation conditions (horizontal or vertical installation), and other related details. If you are not very familiar with these, it’s okay; our sales manager will assist you in determining them.

    Q

    Do you have centrifugal pumps in stock?

    A

    There are many models and configurations of centrifugal pumps. Except for a small number of commonly used standard models that are in stock, the vast majority of models and configurations are not stocked and are customized products. We need to first select the pump based on your site conditions such as flow rate, head, medium temperature, pH value, and installation conditions. After determining the pump model and configuration, we can then place an order with the workshop for production.

    Q

    What is your usual delivery time?

    A

    Models in stock can be shipped by the next day at the latest. Others are custom-made, and depending on the product size and specific project conditions, the delivery time is generally between 7-90 days. Please consult our sales manager for details: 0731-88632200 。
