It can be used to transfer cleaning solutions, reagents, waste liquids, and other liquids in instrument fluid paths. Before selection, confirm the compatibility of the liquid with the diaphragm, valves, pump head, and other wetted materials.
300 mL/min 2-Wire Brushless Miniature Liquid Diaphragm Pump | 12V/24V
DPL30-BB is a self-priming miniature liquid diaphragm pump with a two-wire brushless DC motor for liquid supply, wash-fluid replenishment and low-flow recirculation in automated instruments. The diaphragm and check valves form the pumping mechanism, isolating the wetted chamber from the drive. Two-wire power connection supports straightforward integration with the instrument's power and on/off control.
Choose a 12 V or 24 V version with a free-flow rate of 300 mL/min, a rated pressure of 100 kPa and a self-priming suction height of 6 mH₂O. The PPS pump head is available with an EPDM diaphragm and EPDM valves, or a PTFE diaphragm and FFKM valves. Specified brushless service life is 10,000 h at rated voltage in continuous operation.
Wiring, connections and service-life targets can be tailored to the instrument's duty cycle and maintenance requirements. Projects requiring a separate speed-control input or speed feedback can specify a suitable drive and lead configuration. Service-life validation uses the intended fluid, load and start-stop cycle.
Typical Applications:
Cleaning-solution transfer, reagent transfer, waste-liquid discharge, line priming, liquid circulation

Free-flow and pressure ratings apply to different test conditions. Use the performance curve to check the installed duty point.
Wetted materials, harness and dimensions follow the full model and supplied version.
Service-life ratings apply at rated voltage under continuous operation: 3,000 h for brushed motors and 10,000 h for brushless motors. Actual life also depends on media, load, temperature and start-stop frequency.
