CZ type standardized chemical process pump

CZ type standardized chemical process pump is a horizontal, single-stage, single suction pump for petroleum useChemical centrifugal pumpIts size and performance comply with DIN2456, ISO2858, GB5662-85 standards, and it is the basic product of standardized chemical pumps. Product execution standards: API610 (10th edition), VDMA24297 (light/medium). The performance range of CZ series standardized chemical pumps includes all the performance indicators of IH series standardized chemical pumps, such as efficiency and cavitation performance, which exceed those of IH type pumps and can be interchanged with IH type pumps as a single machine. The characteristic curve is flat, suitable for selection when there are relatively large changes in flow rate. The chemical pump has low cavitation value and high efficiency, and maintains these characteristics even when under load. Suitable for transporting low or high temperature, neutral or corrosive, clean or containing solid particles, toxic and flammable media. Mainly used in industries such as chemical, petrochemical, steel mills, power plants, papermaking, food, sugar production, etc.

Scope of application of CZ type standardized chemical process centrifugal pump

CZ standardized chemical pumpCan transport inorganic and organic acid solutions such as concentrated acid, nitric acid, hydrochloric acid, and phosphoric acid at various temperatures and concentrations; Alkaline solutions such as sodium hydroxide and sodium carbonate at various temperatures and concentrations; Various salt solutions; Various liquid petrochemical products, organic compounds, and other corrosive liquids. This type of pump is suitable for refineries, coal processing engineering in the petrochemical industry, low-temperature engineering, paper industry, sugar industry, water supply plants, seawater desalination plants, power plants, environmental engineering, and shipbuilding industry.

Advantages and structural features of CZ type standardized chemical process pump products

Product advantages:

1. CZ standard chemical pump is coaxial, with good concentricity, low vibration, low noise, and smooth operation.
2. Different materials of castings and seals can be used to transport clear water, warm water, hot water, and various liquid media.
3. Adopting Y2 and YX3 high-efficiency energy-saving motors, equipped with high-quality domestic bearings, with high starting torque, high efficiency, low vibration, low noise, reliable operation, and long service life.
4. Reasonably select mechanical seal materials to ensure long-term leak free operation of the pump and save more than 50% of operating and management costs.
When using imported mechanical seals and bearings, the reliability of the product is stronger.

Structural features:

Pump body: horizontal rear opening door structure, pump head and motor connected by coupling, installed on the bottom plate, impeller with rear opening, three bearings, shaft seal with external mechanical seal, equipped with cooling device,Observe the oil level of the bearing body with an oil mirror; Compact and reasonable structure. The pump is cast with legs on the pump body and adopts a foot support structure, which can withstand the load from the pipeline and directly transmit it to the foundation. This way, the pump rotor will not bend due to the load borne by the pump, ensuring the best service life of the bearing and mechanical seal. During maintenance, there is no need to open the pipeline connected to the pump body. Simply open the bolts between the bracket and the pump body and separate them to repair the impeller and mechanical seal, which is simple and convenient.

Impeller: Closed, semi open, fully open impeller. The axial force of CZ chemical centrifugal pump is mainly balanced by the back blade or balance hole, and the residual axial force is borne by the bearing.

Pump cover: forms a sealed chamber with the sealing cover, and the standard chamber size can be equipped with various sealing types.

Shaft seal: Depending on the working conditions, packing seal, single end face machine seal, double single-sided machine seal, series connection seal and other forms can be used

Bearing: The lubrication method is thin oil lubrication, and the oil level is controlled by a constant position oil cup to fully ensure that the bearing works in a well lubricated state.

Shaft: protected by a shaft sleeve to prevent direct contact between the medium and the shaft from corrosion, thus improving the service life of the shaft.

Rear drag design: It can be repaired without moving the pump's inlet and outlet pipelines, making it easy to use.
