The CZ horizontal chemical process pump is an upgraded version of the standard CZ pump, designed in accordance with the 8th edition of the American Petroleum Institute (API) 610 standard. This design simplifies equipment upgrades and features a horizontal suspended structure with a radial section and rear single-suction single-stage configuration. The use of an extended coupling allows for maintenance without moving the motor or removing the pipeline, making it highly convenient for service and repair.
This pump is capable of handling liquids that are slightly corrosive and operate within a specific temperature range. It is ideal for applications in the refining, chemical, and petrochemical industries where reliability and performance are critical.
**Key Features:**
1. **High Standards Compliance:** The CZ pump has been upgraded to meet the technical requirements of API 610, 8th edition, which exceeds both the previous 6th edition of API 610 and national standards such as GB 3215-83 and GB 5656-1994.
2. **Advanced Casting Process:** Over-flow components like the pump body, impeller, cover, and seal ring are manufactured using precision silicone mold casting. This ensures accurate dimensions and improved flow stability. After casting, a pickling process removes surface residues, preserving the metal’s integrity and preventing contamination.
3. **Double Volute Casing:** For large-diameter pumps (80mm and above), the double volute casing design effectively reduces radial pressure, improving efficiency and performance.
4. **Cooling Chamber Design:** The pump cover includes a water-cooling chamber, which helps protect mechanical seals and bearings from high-temperature media, extending their lifespan.
5. **Mechanical Sealing Options:** The pump offers various sealing configurations—single-ended, double-ended, or metal bellows—ensuring reliable and efficient sealing under different operating conditions.
6. **Back Impeller and Balance Holes:** A back impeller combined with balance holes helps manage axial forces and reduce pressure in the seal chamber, enhancing seal performance and longevity.
7. **Heavy-Duty Bearings:** Equipped with high-capacity bearings using oil lubrication, ensuring strong load-bearing capacity and a long service life exceeding 25,000 hours.
8. **Flexible Coupling Options:** The pump supports flexible pin or diaphragm couplings (with elongated versions available for diaphragm types), offering high torque capacity and efficient power transmission.
9. **Fully Sealed Shaft:** The shaft is sealed with O-rings before and after the impeller and bushings, preventing contact with the pumped medium and increasing shaft durability.
10. **High Pressure Capacity:** Designed for a maximum working pressure of 2.5 MPa, this pump outperforms standard IH pumps, which typically operate up to 1.6 MPa.
**Operating Conditions:**
- Flow Rate: 13 to 2000 m³/h
- Head: 14 to 160 m
- Temperature: -80°C to +140°C (standard type), +140°C to +300°C (with cooling chamber)
- Diameter: 32 to 300 mm
- Ambient Temperature: ≤ 40°C
- Maximum Working Pressure: ≤ 2.5 MPa
This pump is a robust and versatile solution for a wide range of industrial applications, combining advanced engineering with user-friendly design for easy maintenance and long-term reliability.
One-hole Basin Faucets are much more user-friendly than the rest basin faucets. Installation is simple and requires the drilling of only one hole.
