OVERVIEW

The CPH Horizontal Shielded Chemical Pump with heat exchanger integrates a shielded motor and pump into a single unit. It features a design where the stator’s inner surface and the rotor’s outer surface are covered with a thin-walled, non-magnetic, corrosion-resistant metal cylinder. This design ensures that the stator windings and rotor core are completely isolated from the conveyed medium, protecting against erosion and ensuring a leak-proof operation.

Key Features

• High-Temperature Capability: Designed to handle high-temperature liquids, with temperature ranges suitable for demanding applications.
• Leak-Proof Design: Completely prevents leakage, making it suitable for transporting hazardous liquids, including those that are harmful, explosive, flammable, precious, or corrosive.
• Isolation from External Air: Ideal for liquids sensitive to exposure to external gases, ensuring that the conveyed liquid remains uncontaminated.
• No Shaft Seals: Operates without shaft seals, making it suitable for high-pressure systems, high-melting point liquids, and applications involving high or low temperatures.
• No Lubrication Required: Eliminates the need for lubrication, preventing contamination of the liquid and avoiding the complications associated with oil filling and drainage.
• Compact and Lightweight: Features a coaxial integration of the motor and pump, resulting in a compact design, reduced weight, and minimal footprint, facilitating easy maintenance and inspection.
• Low Vibration and Noise: Utilizes water or natural cooling without a fan, resulting in smooth operation with low vibration and noise levels.

ADVANTAGES

1. Long Service Life:
   • Automatic Hydraulic Thrust Balance System: Features an advanced hydraulic thrust balance system, combined with silicon carbide bearings, which significantly extends the pump’s service life.
2. High Efficiency:
   • Optimized Motor Design: Incorporates an optimized motor design and efficient hydraulic research, resulting in excellent energy efficiency and reduced operational costs.
3. High Reliability:
   • Advanced Processing and Testing: Manufactured using state-of-the-art processing techniques and high-end CNC equipment, ensuring consistent and reliable product quality.
   • Bearing Wear Monitoring: Equipped with bearing wear monitoring for online surveillance and automated control, enhancing operational reliability.
4. Secondary Sealing Shell:
   • Safety Assurance: Features a secondary sealing shell to ensure environmental safety in the event of an accident, providing additional protection against leakage and contamination.

STRUCTURAL CHARACTERISTICS

1. Shielded Motor and Pump Integration:
   • Non-Magnetic Corrosion-Resistant Metal Sleeve: The inner surface of the stator and the outer surface of the rotor is covered with thin-walled, non-magnetic, corrosion-resistant metal sleeves. This design ensures complete isolation of the stator windings and rotor core from the conveyed medium, preventing corrosion.
2. Absolute Leakage-Free Design:
   • Directly Mounted Impeller: The impeller is mounted directly on the rotor’s shaft extension, and the entire rotor assembly is submerged in the conveyed liquid. This design eliminates any rotating components that connect to the external environment, ensuring zero leakage.
3. Suitability for Various Liquids:
   • Harmful and Explosive Liquids: The leakage-free design makes it suitable for handling harmful, explosive, and flammable liquids, as well as precious and corrosive fluids.
   • Sensitive Liquids: The pump is ideal for fluids that could deteriorate when exposed to external gases due to its complete isolation from the outside air.
4. High Pressure and Temperature Applications:
   • No Shaft Seals: Suitable for high-pressure systems, high melting point liquids, and fluids at both high and low temperatures due to the absence of shaft seals.
5. Maintenance and Operational Efficiency:
   • No Lubrication Needed: The pump does not require lubrication, which prevents contamination of the conveyed liquid and avoids the hassle of oil filling and draining.
   • Compact and Lightweight: The motor and pump are co-axial, resulting in a compact, lightweight design that requires less space and simplifies disassembly and inspection.
6. Quiet and Stable Operation:
   • Water or Natural Cooling: The motor uses water cooling or natural cooling without a fan, leading to low vibration and noise levels during operation.

APPLICATION

• High-temperature liquid transfer
• Hazardous or corrosive liquids
