DPL30H is a high-pressure miniature liquid diaphragm pump with a no-load flow rate of 300 mL/min and a pressure rating of 600 kPa. The standard DPL30 has the same no-load flow rating and a pressure rating of 100 kPa. DPL30H is more suitable for fluid paths with higher back pressure or tubing resistance.

600 kPa Brushed High-Pressure Liquid Diaphragm Pump for OEM Systems
DPL30H-DS is a self-priming high-pressure liquid diaphragm pump with a brushed DC motor for OEM liquid supply, filtration and washing duties. It is intended for fluid circuits with higher backpressure from filters, narrow-bore tubing or multiple valves. The positive-displacement diaphragm and check-valve mechanism integrates with equipment sequences through power-switched on/off control.
Choose a 12 V or 24 V version with a free-flow rate of 300 mL/min, a rated pressure of 600 kPa and a self-priming suction height of 3 mH₂O. Wetted-material combinations use a PPS pump head with an EPDM diaphragm and EPDM valves, or a PTFE diaphragm and FFKM valves. Specified brushed service life is 3,000 h at rated voltage in continuous operation.
OEM adaptation includes connections, mounting and wiring, with development available for application-specific service-life targets. The configuration is matched to target backpressure, required delivery, fluid and start-stop cycle, then confirmed by flow and endurance testing in the corresponding fluid circuit.
Typical Applications:
High-back-pressure liquid transfer, cleaning-solution transfer, reagent transfer, 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.
