Introduction:CZ type chemical process pump is a product produced by introducing advanced foreign technology. This pump is a horizontal, single-stage, single suction centrifugal pump, which is currently one of the more advanced pump types in China. This type of pump can transport inorganic and organic acids such as nitric acid, sulfuric 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, as well as various salt solutions; Various liquid petrochemical products, organic compounds, and other corrosive liquids.

The components of CZ type chemical process pumps that come into contact with the medium are commonly made of materials such as 0Cr18Ni9, 1Cr18Ni9, 0Cr18Ni9Ti, 1Cr18Ni12Mo2Ti, 40Cr, Monel, 1Cr18Ni12Mo2Ti, Ti (titanium), 00Cr17Ni12Mo2Ti, Hastelloy B alloy, 0Cr25Ni20, F5 series alloy, 20 alloy steel, 0Cr25Ni6Mo3Cu2Mn2Si, etc. The shaft seal adopts single or double end mechanical seal or soft packing seal, and users can choose according to actual working conditions.

Explanation of pump model meaning:

Structural features:The CZ series pump body is foot supported and can withstand external loads directly transmitted to the foundation. The bearing lubrication method is thin oil lubrication, controlled by a constant position oil cup to ensure that the bearing works in good lubrication condition and has a better service life. The impeller is a semi open impeller, which balances axial forces with back blades or balance holes, and residual axial forces are balanced by bearings. Some pump bodies are designed with dual shaft seals. Depending on the usage situation, power seals and dual machine seals can be used. Internal flushing, self flushing, and external flushing can be used to flush and cool the mechanical seals. Deep groove ball bearings, cylindrical roller bearings, and angular contact ball bearings are equipped with light and heavy shafts respectively to meet the needs of different loads. The CZ series pumps require only 8 types of bearing frames for 42 models, with strong universality, high standardization, compact and reasonable structure, and good appearance quality. Couplings are available in claw type, pin type, diaphragm type, etc. for users to choose from. The membrane can be packaged, and there is no need to disassemble the pipeline and motor during maintenance. The bearing frame, shaft, sealing box, impeller components, etc. can be freely disassembled. The inlet flange of the pump is horizontally suction, and the outlet flange is vertically upward. From the motor end, the pump shaft rotates clockwise.

Performance parameter table

Users should pay strict attention when using it

1、 Lubricating oil should be added to the bearing box, and the oil level should be controlled at the middle level of the oil window.

2、 Before driving, manually rotate the coupling to check for any jamming during installation. If there are any scratches or abnormalities, they should be eliminated.

3、 Before starting, connect the coolant flushing solution first. When stopping, stop the vehicle first and then turn off the coolant flushing solution.

4、 The cooling flushing fluid must be clean, non scaling soft water, so newly installed pipelines and storage tanks should be flushed clean. Prevent solid substances from entering the mechanical seal and affecting the sealing effect and service life. Water that is prone to scaling can block the cooling flushing fluid pathway. It will also affect the effectiveness and lifespan of the seal.

5、 The use of condensed water as a sealing flushing solution is ideal, with a temperature below 85 ℃.

6、 The pressure of the cooling flushing liquid is 0.1~0.3 MPa, and the flow rate is 0.63 m3/h. If the flow rate is too small, it will affect the service life of the seal.
