You must pick the right pump for your chemicals. Metallic magnetic drive pumps work with many acids and bases. They handle sulfuric, hydrochloric, and nitric acid. You can use them for toxic materials in farms and factories. These pumps resist chemicals and stop leaks.
Plastic-lined pumps protect against even stronger chemicals. The plastic lining keeps the pump safe from acids and caustics. People use these pumps in chemical plants and drug companies. They move dangerous or sensitive liquids without rust or damage. If you need to move hazardous waste, plastic-lined pumps are safer.
Tip: Always look at the chemical compatibility chart before you pick a pump. This helps you avoid problems and saves money.
Temperature and Pressure Limits
Metallic magnetic drive pumps work with high heat and pressure. Some pumps handle up to 2680 PSI and 500°F. You can use them for hot and rough fluids. These pumps keep working when things get tough.
Plastic-lined pumps do best with lower heat and pressure. The lining can break if the liquid is too hot or strong. If your process stays under 250°F and does not need high pressure, these pumps are fine. For hotter or stronger jobs, use a metallic magnetic drive pump.
Durability and Maintenance
You want pumps that last and do not break often. Metallic magnetic drive pumps have strong metal bodies. They resist scratches and last a long time. These pumps need little fixing and work well for hard jobs.
Plastic-lined pumps fight rust but may not handle sharp stuff. The lining stops damage from chemicals, but sharp bits can hurt it. You should check the lining often. These pumps are easy to clean and fix, so you avoid long stops.
Note: Regular checks help both pumps work well and stop leaks.
Cost and Installation
Metallic magnetic drive pumps cost more at first. You pay for their strength and ability to handle heat and pressure. They last long and work well in tough places.
Plastic-lined pumps cost less to buy. They are easy to set up and work for many jobs. If you move chemicals at lower heat and pressure, these pumps save money and protect your process.
Typical Applications
You see metallic magnetic drive pumps in many places. They move chemicals, strong liquids, and toxic stuff. You find them in chemical plants, drug factories, paper mills, textile plants, food factories, and water treatment. They also help with unloading rail cars and metal finishing.

Common Mistakes with Metallic and Plastic-Lined Pumps
Chemical Compatibility Errors
Some people think every material works with all liquids. This is not true. Many forget to check how fluids react with pump parts. If you skip this, the pump can get damaged or corroded. Always use a chemical resistance guide before picking a pump. Metals and plastics react in different ways to acids and bases. Even small impurities can cause problems. You should know how each part inside the pump handles your fluid. This step keeps your process safe and helps your equipment last longer.
Tip: Do not guess about chemical compatibility. Always check a chart or ask NTGD for help.
Ignoring Temperature or Pressure Limits
Some users do not pay attention to temperature or pressure limits. Using a pump above its rating can cause leaks or make it fail. Metallic pumps work with higher heat and pressure. Plastic-lined pumps have lower limits. Always match your process needs to the pump’s ratings. This helps you avoid breakdowns that cost money.
Overlooking Maintenance Needs
People sometimes forget pumps need regular checks. Skipping maintenance can cause dry running, motor overload, or cavitation. These problems can damage the pump fast. Make sure there is enough liquid in the system. Check for blockages often. Even a closed valve or a pump that is too big can cause trouble. Regular inspections help you find problems early and keep things running well.
- Dry running makes heat and damages the pump.
- Motor overload causes overheating.
- Cavitation shakes the pump and breaks parts.
- Decoupling can stop the pump from working.
