Exploring API610 Chemical Process Fluorine-Lined Centrifugal Pumps

May 08, 2025

Introduction When it comes to moving liquids in chemical production, safety is a big deal. A lot of the chemicals used can be really harsh, so centrifugal pumps need to be reliable both in how they work and what they’re made of. The API610 fluoroplastic-lined centrifugal pump is designed for these tough jobs, making it a solid option for handling tricky situations. 01 Versatile Applications You’ll find the API610 fluoroplastic-lined centrifugal pump in many different industries thanks to its solid performance. In petrochemical fields, it handles tough acids like sulfuric, hydrochloric, and nitric, along with strong bases like sodium hydroxide, keeping operations smooth. It’s also effective for acidic or alkaline wastewater in metallurgy. Even sectors like pharmaceuticals, paper, and textiles count on these pumps to move corrosive liquids, showing how flexible they can be. 02 Working Principle This pump has a few main components: the pump body, impeller, and shaft seal, among others. Here’s the basic idea of how it works: - The motor spins the impeller, which pushes the liquid through the pump. - Centrifugal force drives the liquid outwards, creating a low-pressure area at the center. - External pressure then pulls the liquid into the impeller. - As the liquid speeds up, it enters the volute, where its speed is converted into pressure, allowing it to be discharged at a high pressure. The fluoroplastic lining is crucial for preventing corrosion, as it protects the key parts like the impeller and pump body. This material holds up well against almost all corrosive substances, helping the pump last longer and perform reliably in harsh chemical environments. 03 Key Usage Considerations To keep everything running safely and smoothly, keep these tips in mind: - Pre-startup Checks: Ensure valves are set correctly (inlet fully open, outlet closed) and prime the pump to prevent damage from running dry. - Operational Monitoring: Watch for flow rate, pressure, and current. If something feels off, stop the pump immediately. - Temperature Control: Stick to the recommended temperature range to avoid issues with the lining. - Seal Maintenance: Regularly check the shaft seals for leaks and replace worn parts quickly. - Avoid Low-Flow Operation: Running at low flow for too long can hurt efficiency and cause overheating. The API610 fluoroplastic-lined centrifugal pump plays a big role in moving chemical liquids because it can handle tough environments and is designed smartly. Following the operational tips helps ensure it runs smoothly, making it an important piece of equipment in today’s chemical production.

SEMICON China 2025

April 08, 2025

SEMICON China 2025: Chemical Pumps and the Semiconductor Industry SEMICON China 2025 has kicked off in Shanghai, shining a light on the important role of chemical pumps in the semiconductor world. Even though they might not get much attention, chemical pumps are crucial in semiconductor manufacturing. They need to perform really well because the process demands ultra-clean conditions. For instance, pumps that transport ultrapure water have to be made from special materials that resist corrosion and don’t pollute the water. This is vital to keep impurities from messing up chip production. Additionally, these pumps must be precise in controlling flow and pressure, which is necessary for complex tasks like etching and cleaning. At SEMICON China 2025, many companies are showcasing their latest advancements in chemical pump technology. These innovations are expected to boost the efficiency and quality of semiconductor manufacturing, supporting China's push to advance its semiconductor industry.

What should be done when a pump is idling?

March 07, 2025

What should be done when a pump is idling? Causes of idling in centrifugal pumps: The medium at the inlet of the pump is insufficient or the inlet pressure is too low, or the inlet pipeline of the pump is blocked, or the air in the pump chamber has not been completely discharged. Hazards When a centrifugal pump is idling, the impeller does not contact or contacts very little with the medium, and cannot work effectively. The liquid cannot be transported normally, which is all doing useless work. Since there is no effective work being done, the load on the motor is very small, and the generated current is also small, so there is no significant impact on the motor. However, idling has a fatal impact on the pump. An idling pump is prone to cavitation, causing damage to the pump body and flow-through components; Whether it is a mechanical seal or a packing seal form for an idling pump, without the lubrication of the liquid, dry grinding will occur, resulting in rapid damage; The rotor components and pump body of an idling pump will heat up. Without the cooling effect of the liquid, due to thermal expansion and contraction, those narrow clearance positions (such as the sealing ring) are very likely to seize; For a multi-stage centrifugal pump that is idling, the balance disc has no lubrication from the liquid, and the balance disc will soon be burned out and damaged. Prevention and Recommendations 01 Clearance Treatment Treat each clearance position of the centrifugal pump. Expand it under permissible conditions to prevent seizing; 02 Pump Shaft Treatment Perform special processes such as quenching and tempering, heat treatment, etc. on the shaft of the centrifugal pump to increase its hardness. Use materials with low flexibility to prevent significant swinging and seizing during idling; 03 Seal Treatment Use a mechanical seal or packing cavity that does not rely on liquid medium for lubrication; 04 Bearing Treatment Select a sealed, self-lubricating bearing that does not require oiling. Recommendations The pump chamber of a horizontal self-priming centrifugal pump has a relatively larger volume space compared to other centrifugal pumps, and there is a position that can store water. Before the normal operation of the self-priming centrifugal pump, the chamber should be filled with liquid. During the startup phase, there is a period of self-priming time during which air is continuously discharged out of the pump body. This period belongs to partial idling. Set up an idling sensing system. Use modern equipment to monitor the water pump in real-time. When the centrifugal pump idles, immediately sound an alarm and automatically shut down to protect the safety of the unit.
