How to Choose the Right Walchem Metering Pump?

• Determine flow rate & pressure requirements – Don’t oversize. Match the pump capacity to your system needs.
• Check chemical compatibility – Always confirm that the materials (seals, diaphragms) suit the fluids in use.
• Decide on control style – Choose between manual control, analog input, or pulse input, depending on your process.
