It can be used to transfer cleaning solutions, reagents, waste liquids, and other liquids in instrument fluid paths. Before use, confirm the compatibility of the liquid composition, concentration, and temperature with the diaphragm, valves, pump head, and other wetted materials.
300 mL/min Brushed Micro Liquid Diaphragm Pump for OEM Instruments
DPL30-DB is a self-priming miniature liquid diaphragm pump with a brushed DC motor for wash-fluid delivery, reagent transfer and line priming in IVD, analytical and laboratory instruments. A reciprocating diaphragm and inlet and outlet check valves move the liquid, while the diaphragm separates the wetted chamber from the motor drive.
Available in 12 V and 24 V versions, the pump has a free-flow rate of 300 mL/min, a rated pressure of 100 kPa and a self-priming suction height of 6 mH₂O. Wetted-material options pair a PPS pump head with either an EPDM diaphragm and EPDM valves, or a PTFE diaphragm and FFKM valves. Specified service life is 3,000 h at rated voltage in continuous operation.
OEM adaptation covers wiring, port orientation and installation requirements, with development available for project-specific service-life targets. Materials and drive configuration are matched to the fluid, backpressure, start-stop frequency and daily operating hours; endurance testing under agreed conditions validates the target.
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.
