600 kPa Brushed High-Pressure Liquid Diaphragm Pump for OEM Systems

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

DPL30H-DS configurations

Select the required options (Rated voltage and Material combination) and save the configuration for your inquiry.

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.

Frequently Asked Questions

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.

It is suitable for cleaning-solution transfer, reagent transfer, and liquid circulation where higher tubing resistance, longer fluid paths, or higher back pressure must be overcome.

Yes. Actual flow may decrease as operating pressure and fluid-path resistance increase, so testing should be performed under the equipment’s actual pressure conditions.

The brushed version has a service life of 3000 h. Actual service life may also be affected by load, start-stop frequency, and operating environment.

Consider DPL30H when the standard DPL30 cannot overcome fluid-path resistance or when the equipment has a higher back-pressure requirement.

Foreach miniature diaphragm pumps for OEM integration: operating points, instrument validation and production introduction

Whether the miniature diaphragm pump can work stably in OEM instruments depends on the joint matching of fluid path tasks, inlet and outlet conditions, material combinations, control methods and overall machine structure. Taking Foreach DPL30, DPL60, DPL30H and DPGL800 as examples, this article starts from the flow and pressure budget, gas-liquid status, wetted materials and electrical interfaces to explain how to establish candidate solutions, carry out reproducible prototype verification, and convert the verification results into technical requirements for production supply.

What Are Cleaning, Wash and Rinse Pumps in IVD Systems, and Why Are Miniature Diaphragm Pumps Used?

Cleaning pump, wash pump and rinse pump usually name different duties within an IVD cleaning sequence, not three fixed pump mechanisms. Selection starts with wash volume, cycle rate, line resistance, wetted materials, and whether the duty is liquid supply or waste aspiration.

How Should You Select EPDM, PTFE and FFKM for a Micro Diaphragm Pump?

EPDM, PTFE and FFKM are not a simple low-to-high material ranking. EPDM and FFKM are elastomers, while PTFE is a fluoropolymer; the diaphragm, valves and pump head perform different mechanical jobs. Selection therefore applies to a complete wetted and dynamically loaded structure, not one material name.

Why Does Actual Flow Change So Much When the Tubing Size Changes on the Same Miniature Diaphragm Pump?

Even when the pump is unchanged, installed flow can change because of tubing inner diameter, length, bends, and the minimum bore of fittings. When flow falls after a tubing change, the effective response is neither to blame the pump first nor to enlarge every tube indiscriminately. Measure inlet pressure, outlet pressure, and accumulated flow together to determine where the added restriction actually occurs.

Which Has a Greater Effect on a Miniature Diaphragm Pump: Suction-Line or Discharge-Line Resistance?

Pressure loss on either the suction or discharge side increases the differential pressure carried by a miniature diaphragm pump, but there is no universal rule that one side is always more important. The suction side more readily affects initial priming, chamber filling, sensitivity to air leakage, outgassing, and cavitation. The discharge side more often appears as increased backpressure, reduced flow, and deadheading. Diagnose the system by observing inlet absolute pressure, outlet pressure, and flow on the same time axis.

What Is the Difference Between Rated Working Pressure, Maximum Output Pressure, Proof Pressure, and Burst Pressure for a Miniature Diaphragm Pump?

A pressure value has engineering meaning only when it is paired with a term definition, test fluid, inlet condition, corresponding flow rate, duration, and acceptance criteria. Rated working pressure can define an operating boundary; maximum output pressure, proof-test pressure, and burst pressure cannot be treated directly as continuous operating points.

Is 100 kPa Enough? How to Determine Whether a Fluid Path Needs a 600 kPa High-Pressure Miniature Diaphragm Pump

100 kPa and 600 kPa are not simply a standard version and an upgraded version. First complete a pressure budget for the entire fluid path at the target flow, then read the candidate pump curve. A higher pressure rating has value only when the application truly has high backpressure.

How Do You Build a Pressure Budget for a High-Backpressure Fluid Path? A Foreach 600 kPa Miniature Diaphragm Pump Selection Example

For a high-backpressure fluid path, do not tell a supplier only that you need 6 bar. Break down steady-state pressure losses at the target flow, establish normal steady-state, worst steady-state, pressure-margin, and transient-protection boundaries separately, and then compare them with the candidate pump's controlled curve.

How to Select a High-Pressure Diaphragm Pump: DPL30H 300 mL/min and 600 kPa Guide

Filters, narrow rigid tubing, valves, mixing chambers and long lines all create pressure drop. As backpressure rises, a pump's delivered flow falls, so no-load flow alone is not a valid selection criterion. DPL30H is designed for liquid paths that need greater pressure margin: 300 mL/min no-load flow and 600 kPa rated pressure.

How to Read a Diaphragm Pump Flow-Pressure Curve—and Predict Installed Flow

A catalogue value such as 300 or 600 mL/min is not a fixed flow rate inside an instrument. The useful engineering question is: at the actual inlet pressure, outlet backpressure, fluid, tubing and supply voltage, where will the pump and the fluidic circuit settle?

2-Wire vs 5-Wire Brushless Diaphragm Pumps: What Is the Difference and Which Should You Choose?

When selecting a miniature diaphragm pump, two lead configurations may be offered for the same type of DC brushless motor: 2-wire and 5-wire. The main difference is not the pump's basic delivery principle, but how much control and operating-status information the equipment requires from the motor.
