Compact 12V Self-Priming Diaphragm Liquid Pump With 0.4L/min Flow, 10m Head, and Dry-Running Capability
The TOPSFLO TF30A-A12-W1004 is a compact diaphragm liquid pump designed for analytical instruments, medical equipment, laboratory systems, water treatment, printing equipment, cleaning systems, and other applications requiring controlled liquid transfer in a small footprint. Operating from a 12V DC supply, the pump provides approximately 0.4L/min maximum liquid flow and at least 10m maximum water head, making it suitable for low-flow applications requiring useful pressure capability.
The pump uses a premium-duty brushed DC motor and an eccentric-driven diaphragm mechanism to generate liquid flow without requiring lubricating oil in the fluid path. Its self-priming and dry-running capabilities simplify integration into portable and embedded equipment, while standard nylon, EPDM diaphragm, and EPDM valve construction supports many general-purpose liquids. Alternative PTFE, FPM, FFPM, and other material configurations can be specified for applications involving chemically aggressive media.
Key Features
- 0.4L/min Maximum Liquid Flow: Provides controlled fluid transfer for compact analytical, medical, and industrial systems.
- 10m Maximum Water Head: Supports applications requiring approximately 1bar-class pressure capability.
- 12V DC Operation: Suitable for embedded equipment, instruments, portable systems, and DC-powered machinery.
- Brushed DC Motor: Uses the premium-duty brushed motor associated with the TF30A-A series.
- Approximately 3000-Hour Ideal Life: Current TF30A-A series documentation specifies approximately 3000 hours of ideal service life.
- Self-Priming Operation: Can establish suction without requiring the inlet line to remain continuously flooded.
- Dry-Running Capability: Designed to tolerate dry operation under specified operating conditions.
- Diaphragm Pump Technology: Uses an eccentric mechanism and flexible diaphragm to create controlled liquid movement.
- Oil-Free Fluid Path: Does not require lubricating oil in the working chamber, helping reduce contamination risk.
- Good Pressure Capability: Diaphragm design provides useful pressure performance despite the compact pump size.
- Low-Pulsation Transfer: Suitable for controlled liquid delivery in analytical and processing systems.
- Compact Construction: Small overall dimensions help simplify integration into space-constrained equipment.
- Multiple Mounting Positions: Can be installed in different orientations according to equipment-layout requirements.
- Low Vibration: Optimized diaphragm, eccentric, and bearing construction helps reduce mechanical vibration.
- Low-Noise Design: Manufacturer specifies a maximum noise class of approximately 50dB at 1m.
- Nylon Pump Head: Standard pump-head construction provides lightweight and practical fluid handling.
- EPDM Diaphragm: Standard configuration supports water and many compatible general-purpose liquids.
- EPDM Valves: Provides reliable inlet and outlet control in standard configurations.
- Chemical-Resistance Options: PTFE, FPM, FFPM, and other wetted-material combinations can be specified for compatible aggressive liquids.
- Continuous or Intermittent Operation: Supports different operating cycles according to system requirements and application conditions.
- Minimal Maintenance: Simple diaphragm architecture reduces routine service requirements.
