It is suitable for automated equipment with higher back pressure or tubing resistance and higher requirements for operating life and maintenance intervals.

12V/24V Brushless High-Pressure Liquid Diaphragm Pump | PWM Option
DPL30H-BS is a self-priming high-pressure liquid diaphragm pump with a brushless DC motor for liquid supply against backpressure, wash-fluid transfer and recirculation in analytical, IVD and laboratory automation equipment. Its diaphragm separates the wetted chamber from the drive, making it a candidate for circuits incorporating filters, narrow-bore tubing or valve manifolds.
Available in 12 V and 24 V versions, the pump has a free-flow rate of 300 mL/min, a rated pressure of 600 kPa and a self-priming suction height of 3 mH₂O. PWM or 0–5 V speed-control configurations are available as options. The PPS pump head can be paired with an EPDM diaphragm and EPDM valves, or a PTFE diaphragm and FFKM valves. Specified service life is 10,000 h at rated voltage in continuous operation.
Speed control, feedback, wiring and installation can be adapted for the OEM system, with development to agreed service-life targets. Materials and drive configuration are selected for the operating point, running hours and maintenance interval, then evaluated for performance, temperature rise and endurance using the intended fluid and duty cycle.
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.
