What do these products do in this instrument?
Liquid diaphragm pumps: auxiliary cleaning and liquid supply
Supply liquid to the installed cleaning or auxiliary branches, coordinated with channel flushing and waste destinations. Where detection requires specific flow or pressure, confirm the drive configuration separately for that channel.
Compare DPL30, DPL60 and DPL30H by actual supply load. Wash-head, valve, tubing and container resistance jointly determine installed flow; check the supply window and receiving position together.
Gas–liquid diaphragm pumps: suitable aerated wash-fluid removal
Aspirate incoming liquid in washing-station or waste architectures with gas-containing inlets. Coordinate peak flushing from sampling, reaction and detection channels; configure liquid-only drainage with a suitable liquid-pumping solution.
DPGL800 handles gas or gas–liquid aspiration permitted by its specific configuration. Check inlet gas content, foam, peak inflow and container vacuum; use a separately suitable solution for continuous liquid-only transfer.
Define liquid-supply and aerated-aspiration branches separately
Suitable liquid diaphragm-pump configurations supply wash heads, stations or working vessels. Gas–liquid diaphragm pumps serve permitted aerated aspiration or related container-vacuum architectures. Describe actual inlet medium and gas–liquid state first, then determine pump position, incoming source and discharge destination.
Further technical reading
Match supply/removal capacity to washing-station and container conditions
Installed flow depends jointly on pump, tubing, valves, wash head and container; free flow does not directly represent station delivery. Evaluate supply by effective coverage and available time, and waste removal by peak inflow, lift, permitted residual liquid and full-container state. Check the complete wash cycle when supply and aspiration must be coordinated.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Inlet medium | Distinguish liquid-only flow, intermittent gas entrainment and foam, and confirm the aspiration modes permitted by the configuration. |
| Tubing and containers | Provide suction lift, outlet load, tubing and waste-container conditions. |
| Actual supply and removal | Measure incoming liquid, residue and emptying at the station; check handling after full level, shortage or blockage. |
| Operation | Specific operating conditions |
|---|---|
| Hematology-channel cleaning and waste removal | Wash-fluid formulation, volume/time, spray/aspiration geometry, air/foam and waste capacity |
Compare product configurations by the roles on this page
| Product | Configuration option | Conditions to verify |
|---|---|---|
| DPL30 liquid diaphragm pump | Liquid supply or auxiliary circulation | Select by installed resistance, actual wash or working fluid and task window |
| DPL60 liquid diaphragm pump | Liquid supply or auxiliary circulation | Judge by peak demand and installed operating point, not free flow alone |
| DPL30H high-backpressure liquid diaphragm pump | Liquid branches requiring higher backpressure capability | Calculate pressure budget and actual flow first, then confirm interfaces and materials |
| DPGL800 gas–liquid diaphragm pump | Suitable gas–liquid aspiration or container-vacuum branches | Confirm inlet medium and waste architecture; not for continuous liquid-only transfer (100% liquid) |
Explore specific operating and validation tasks
Hematology-channel cleaning and waste removal
Cleaning must cover sampling, reaction and detection branches; waste removal must handle simultaneous inflow. After restart, check blanks and channel state before resuming sample measurement.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Hematology-channel cleaning and waste removal | Confirm supply and peak waste-removal capacity under installed resistance; measure residual liquid, carryover or assay-specified recovery | Insufficient supply, foam, dry aspiration and a full waste container disrupt the cleaning cycle |
Check sampling, ratios and channel recovery with actual whole-blood conditions, and validate supply stability during continuous testing.
Do similar nominal supply- and waste-pump flow rates make a matched pair?
Compare peak inflow, effective aspiration and permissible accumulation in the actual installation. The branches may handle different media and operating windows; validate station recovery over the complete sequence.
Metered dilution and sheath-fluid flow are different roles; sheath-fluid requirements depend on the detection architecture.
