Features
CYH series pumps have 29 basic types, of which 22 are dual-speed (2900, 1450r/min). After the impeller diameter cutting and modification of A and B types, there are 112 specifications. It is mainly composed of pump body, impeller transmission line, sealing ring, impeller nut, pump cover, sealing parts, intermediate bracket, shaft, suspension parts, etc. It is directly driven by the motor through the extended coupling, and rotates clockwise from the motor end.
The pump cover is fixed on the intermediate bracket through the stopper, and then the pump cover is clamped in the middle through the connection between the pump body and the stopper of the intermediate bracket. The pump body is axially inhaled, radially discharged, and foot-supported, and can be directly fixed on the base.
The suspension parts are fixed on the intermediate bracket through the stopper, and supported on the base by the suspension bracket. For easy disassembly, an extended coupling is designed, and the inlet and outlet connection pipelines, pump body and motor can be removed during maintenance. Only the intermediate connection of the coupling needs to be removed to withdraw the rotor parts for maintenance.
Precautions for using stainless steel caustic liquid centrifugal pump：
The working design pressure of CYH stainless steel alkali centrifugal pump is 1.6 MPa. The medium temperature is not higher than 80℃. Double end face sealing cooling device is used when necessary, and the medium temperature can be transported at 20℃～+280℃.

FAQ
Q1: What is a Caustic Pump?
A1: caustic pump is a specialized pump designed to handle caustic or highly alkaline substances, such as sodium hydroxide (caustic soda). These pumps are constructed from materials that resist corrosion and chemical degradation caused by these highly reactive substances. Caustic pumps are commonly used in industries like chemical manufacturing, water treatment, and cleaning processes where safe and efficient handling of caustic fluids is essential.
Q2: What Type of Pump is best for caustic soda?
A2: The best type of pump for handling caustic soda (sodium hydroxide) is typically a magnetic drive pump or a diaphragm pump.
- Magnetic Drive Pumps: These pumps have no direct contact between the motor and the fluid, reducing the risk of leaks and contamination. They are highly resistant to corrosion and ideal for handling caustic and hazardous chemicals.
- Diaphragm Pumps: These pumps use a flexible diaphragm to move the liquid, providing excellent chemical resistance and are well-suited for highly corrosive or viscous substances like caustic soda.
Both types offer safety, reliability, and durability in handling caustic soda, making them ideal choices depending on the specific application.
Q3: What material is used to pump sodium hydroxide?
A3: Pumping sodium hydroxide (NaOH) requires materials that can resist its corrosive nature. Common materials include:
Thermoplastics:
- Polypropylene (PP): Good chemical resistance.
- PVC: Suitable for lower concentrations.
Metals:
- 316 Stainless Steel: Offers good corrosion resistance.
- Hastelloy: Used for more aggressive conditions.
Lining Materials:
Fluoropolymer Linings (e.g., PTFE): Enhance resistance in metal pumps.
These materials ensure safe and effective handling of sodium hydroxide in various applications.
Q4: What is a Caustic Soda Pump for Dosing?
A4: A caustic soda pump for dosing is a specialized pump used to accurately and safely deliver sodium hydroxide (caustic soda) into a system or process. These pumps are designed to handle the corrosive nature of caustic soda and provide precise flow control, ensuring the right amount is added for applications like water treatment and chemical processing. They are essential for maintaining effective chemical reactions and operational safety.
Q5:Which pump is used for Caustic Soda?
A5: The most commonly used pumps for caustic soda are diaphragm pumps, metering pumps, and peristaltic pumps. These pumps are designed to handle the corrosive nature of caustic soda and provide precise flow control, making them suitable for applications in water treatment and chemical processing.
