Micro Diaphragm Gas-Liquid Pump 1500mL Double Head Diaphragm Membrane Pump Low Pulse BD-05TF1500WBD BODENFLO

Overview of BD-05TF1500WBD Micro Diaphragm Gas-Liquid Pump

The BD-05TF1500WBD is a dual-head small liquid pump designed for OEM systems that require higher total flow within a compact structure. Built with a diaphragm pumping mechanism and a brushless DC motor, it is suitable for analytical equipment, automated liquid handling systems, and gas-liquid transfer platforms.

With 750 mL/min × 2 water flow and 3.5 L/min × 2 gas flow, this model is suitable when one pump needs to support two parallel transfer paths or higher overall circulation capacity. From an OEM selection perspective, it helps reduce component count while keeping liquid and gas transfer functions within one integrated pump design.

Testing Conditions & Measurement Standards

Water Flow Measurement:
Water flow is measured using a high-precision miniature electromagnetic flowmeter (electromagnetic induction volumetric flowmeter).
The test setup includes approximately 1 m inlet and outlet tubing to simulate practical installation conditions.

Noise Measurement:
Noise is measured at a distance of 1 m from the pump during normal operation under standard working conditions.

Lifetime Testing:
Lifetime is evaluated under continuous 24-hour no-load operation, with both inlet and outlet open to atmosphere (ambient pressure conditions).

Standard Materials & Reliability

For most OEM applications, the standard material configuration provides a practical balance of compatibility, sealing performance, and service life.

Component	Material / Feature
Pump Head	PA66
Diaphragm	EPDM
Valve	EPDM
Wetted Materials	PA + EPDM + EPDM

If the standard configuration does not fully match your medium or service life target, additional material options are available for evaluation. Optional configurations such as PTFE diaphragms and FFKM valves can be considered for more demanding chemical compatibility needs.

OEM Customization Options

When the standard version does not fully match your system requirements, key components can be adjusted for better compatibility.

Item	Customization Options
Voltage	12 V / 24 V options; project-based adjustment available
Materials	PA66, EPDM, PTFE, or FFKM options
Wiring	Custom cable length and wire definition
Connector	Open leads, plug connectors, or OEM interface
Branding	Private label or customer-specific marking
Mounting	Bottom mounting structure or custom bracket support

Integrated solutions such as connectors, tubing, and mounting structures can be pre-configured with the pump to match your system layout.
This helps reduce assembly work and makes dual-head pump integration more efficient during OEM development.

Installation & Usage Notes

Proper installation helps maintain flow consistency, protect the pump chamber, and reduce integration issues in OEM liquid handling systems.

Inlet Filtration
Install a ≤30 μm filter at the pump inlet to prevent particles from entering the pump chamber and affecting diaphragm or valve operation.

Bottom Mounting

• Drill 4 × Φ3.2 mm holes at the bottom mounting position
• Use M4 self-tapping screws or M4 screws for board installation
• Ensure the pump is securely fixed to reduce vibration during operation

Wiring Definition

• Red Wire: Power Positive (+)
• Black Wire: Power Negative (–)

Tubing Installation

• Recommended tubing size: ID6 mm / OD8 mm
• Keep tubing connections sealed to avoid leakage, pressure loss, or priming difficulty
• Avoid sharp bending or excessive inlet restriction in dual-channel layouts

Material Compatibility
The standard wetted material configuration is PA + EPDM + EPDM. For chemically aggressive liquids or gases, verify media compatibility before testing and consider optional PTFE diaphragm or FFKM valve configurations.

Operating Environment

• Ambient temperature: 5°C to 40°C
• Fluid temperature: 5°C to 60°C

FAQ – BD-05TF1500WBD Micro Diaphragm Gas-Liquid Pump

Q1: Why is the actual liquid flow lower than the rated 1.5 L/min?

Actual flow can decrease due to tubing resistance, inlet restriction, filter pressure loss, suction height, or system back pressure. Check both flow paths, filter condition, and tubing layout when evaluating pump performance.

Q2: Why should I choose a double-head liquid pump instead of two separate pumps?

A double-head pump integrates two pumping chambers into one compact assembly, reducing the number of motors, wiring, mounting points, and components required. This can simplify system design while providing higher total flow capacity.

Q3: Why does one pump head have difficulty priming liquid?

Uneven priming is usually related to air leakage, different suction conditions, excessive suction height, or restriction in one inlet path. Check both channels separately to ensure similar inlet conditions and proper sealing.

Q4: What is the warranty period for BODENFLO micro pumps?

BODENFLO provides a 1-year warranty for micro pump products. Damage caused by improper installation, incorrect operation, or use outside the specified operating conditions is not covered.

Q5: Are there other diaphragm liquid pumps with similar flow options?

Yes. BODENFLO offers several single-head diaphragm liquid pumps with different flow and pressure ranges for OEM fluid handling systems:

• BD-05TF1500WB – 1.5 L/min water flow, suitable for applications requiring higher single-channel liquid transfer capacity.
• BD-05TF800WBD – 800 mL/min water flow, suitable for medium-to-high flow liquid transfer and circulation.
• BD-05TF700WBD – 700 mL/min water flow, providing another compact option for moderate-flow applications.
• BD-05TF650WBD – 650 mL/min water flow with up to 5 bar maximum water pressure, suitable when higher discharge pressure is required.

The suitable model can be selected according to required flow, pressure, liquid medium, installation space, and operating conditions.
