Which liquid pump specifications matter for an instrument?
Start with the liquid-transfer task: reagent supply, washing or circulation. The DPL series introduction provides a visual starting point; the current product pages provide the configuration-specific data needed for selection.
Required flow at working pressure
Choose the flow at the circuit's operating pressure, rather than the largest free-flow number. Small tubing, filters and downstream valves can reduce delivery compared with an open-outlet test.Motor and control requirements
Brushed and brushless configurations have different drive and control considerations. Confirm voltage, duty cycle, wiring and any speed-control or feedback requirement for the selected motor.Liquid compatibility and installation
Review all wetted materials with the reagent and cleaning sequence. Check the inlet and outlet connection, available mounting space and inlet supply conditions before testing the pump in the instrument.
Compare liquid diaphragm pumps by flow and pressure requirement
DPL30 and DPL60 cover different nominal flow requirements; DPL30H provides a higher-pressure option. The model pages separate motor variants and connection details so you can compare the conditions that matter for your fluid circuit.
