Project Background
The customer is an Indian pharmaceutical manufacturer specializing in pharmaceutical intermediates. During the expansion of its synthesis workshop and wastewater treatment facilities, the customer encountered several challenges related to fluid transfer equipment. The production process involved multiple difficult media, including corrosive chemicals, organic solvents, crystal-containing slurry, and wastewater containing solid particles. The existing pumping equipment could not provide stable long-term operation under these complex working conditions.
The main challenges included:
1. High Abrasion Crystal Slurry Transfer
In the ethanol recovery process, potassium tartrate crystals formed a high-concentration solid-liquid mixture. The original metal pumps experienced frequent wear caused by crystal particles. Mechanical seal failures and blockage issues affected the continuous operation of the production line and increased maintenance requirements.
2. Safe Transfer of Organic Solvents
The production process required the transfer of organic solvents such as DMF and other chemical liquids. Due to the characteristics of solvent applications, the customer required pumps with improved sealing performance and reduced leakage risks to ensure safer operation.
3. Solid-Containing Wastewater Handling
The wastewater treatment system contained solid particles and required pumps with good wear resistance and reliable performance under continuous operation.
Changyu Pump Pharmaceutical Intermediate Transfer Pump Solution
To solve these complex fluid transfer challenges, Changyu Pump adopted a media-specific pumping solution instead of using one pump type for all applications.
Based on the characteristics of each medium, Changyu engineers selected three different pump models:
| Application Process | Pump Model | Core Advantages | Typical Configuration |

| Flammable organic solvent transfer | CQ Stainless Steel Magnetic Drive Pump | Magnetic drive structure eliminates mechanical seal contact and helps reduce leakage risks. Suitable for organic solvent transfer applications. | Flow: 25m³/h; Head: 30m; Power: 7.5kW |
| High-solid wastewater treatment | HB Abrasive Slurry Pump | High-strength alloy materials provide excellent wear resistance for high-concentration solid-liquid mixtures. | Flow: 40m³/h; Head: 45m; Power: 22kW |

Why Recommend These Three Pumps?
The selection of these three pumps was based on the specific characteristics of each medium rather than a standard pump configuration.
- For Crystal Slurry Transfer
- The UHB corrosion resistant pump uses UHMWPE material, which provides excellent wear resistance and chemical resistance. Its low-friction characteristics and anti-adhesion performance help improve the transport stability of potassium tartrate crystal slurry and reduce blockage problems commonly encountered in traditional metal pumps.
- For Organic Solvent Safety
- The CQ magnetic drive pump employs a magnetic coupling structure, reducing the risk of leakage from mechanical seal failure. This design makes it suitable for pharmaceutical and chemical applications involving ethanol and other organic solvents where reliable sealing performance is required.
- For High-Solid Wastewater Applications
- The HB slurry pump is designed for abrasive and solid-containing media. With high-strength metal materials such as 2205 duplex stainless steel, the pump provides improved wear resistance and corrosion resistance for wastewater treatment conditions containing solid particles and corrosive components.
