What do these products do in this instrument?
Liquid Diaphragm Pumps: Auxiliary Medium Supply and Cleaning
Transfer working liquid in bulk-supply or washing branches that actually exist in the instrument, coordinated with reservoirs and valve paths. Confirm medium delivery separately from cell-suspension transfer, and assess wetted configurations under actual culture conditions.
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.
Assign liquid supply to a defined usage branch
This page compares liquid diaphragm-pump configurations for suitable supply paths. Define source, point of use, working liquid and cycle time, then measure liquid arriving at the use point under actual load. Cleaning effectiveness also depends on formulation, coverage and contact time.
Coordinate supply windows with downstream receiving conditions
Tubing, valves and end-use resistance change installed flow. Match supply to permitted container levels or cleaning inflow. Downstream drainage uses its own extraction architecture; check its media and container protection separately rather than inferring them from supply-pump capacity.
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. |
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 |
Confirm product roles in actual operation
Compare viability, recovery and cell condition before and after transfer, and validate the required contamination controls.
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.
Low shear and sterility are validation objectives for the complete flow path. Neither a diaphragm pump nor a pinch valve alone establishes them.
