To replace solvent lines, follow the sequence of steps for the solvent line that you want to replace.
The flow path determines the pump inlet (component at which the solvent enters the pump) and the solvent flow through the pump.
Pump Type | Pump Inlet |
---|---|
Binary pump | The pump inlets are the solvent selectors. |
Isocratic pump | The pump inlet is the pump head. |
Quaternary pump, | The pump inlet is the vacuum degasser. |
For the pump-specific operating principles that illustrate the solvent flow through the pump, see Pump-Specific Information.
Solvent line from the solvent reservoir to the pump inlet: Follow the steps in Solvent Lines From Reservoir To Pump Inlet.
Depending on the pump type
Solvent line from the pump inlet to the proportioning valve or degasser: Follow the steps in Solvent Lines From Pump Inlet to Proportioning Valve or Degasser.
Depending on the pump type
Solvent line from the proportioning valve or degasser to the pump head: Follow the steps in Solvent Line From Proportioning Valve or Degasser To Pump Head.
