Compact 12V Diaphragm Gas Pump With 4.5L/min Flow, 95kPa Pressure And -60kPa Vacuum Capability
The TOPSFLO TM30A-B12 is a compact diaphragm gas-pump platform designed for industrial pressure and vacuum systems, portable analytical instruments, medical diagnostic equipment, gas detection, environmental monitoring, and other applications requiring clean and reliable gas transfer. The 12V configuration provides up to 4.5L/min maximum free flow, with the P9504 pressure version supporting up to 95kPa positive pressure and the V6004 vacuum version reaching approximately -60kPa vacuum.
The TM30A-B uses a brushed DC motor combined with an eccentric-driven diaphragm mechanism to generate pressure or vacuum without requiring lubricating oil in the gas path. Its optimized pump head, diaphragm, valves, and flow passages help reduce vibration and operating noise while maintaining good gas tightness. Standard nylon, EPDM diaphragm, and EPDM valve construction is suitable for general air applications, while alternative chemically resistant material combinations can be specified for selected corrosive gases.
Key Features
- 4.5L/min Maximum Flow: Provides compact gas-transfer capability for analytical, medical, pneumatic, and monitoring equipment.
- 95kPa Maximum Positive Pressure: P9504 pressure configuration supports applications requiring moderate compressed-air pressure.
- -60kPa Maximum Vacuum: V6004 configuration provides vacuum generation for sampling, suction, and analytical applications.
- 12V DC Operation: Suitable for embedded equipment, portable instruments, medical devices, and DC-powered systems.
- Brushed DC Motor: TM30A-B uses a conventional brushed DC motor optimized for compact diaphragm-pump operation.
- Approximately 1500-Hour Ideal Life: Current TOPSFLO product information specifies an ideal service life of approximately 1500 hours for the B-series.
- Oil-Free Gas Transfer: No lubricating oil is required in the working gas chamber, reducing contamination of the pumped medium.
- Diaphragm Pump Design: Uses reciprocating diaphragm movement for pressure and vacuum generation.
- Self-Priming Capability: Can establish suction without requiring a flooded inlet.
- Dry-Running Capability: Designed for gas operation without liquid lubrication.
- Low Vibration: Optimized eccentric, diaphragm, valve, and bearing arrangement helps reduce mechanical vibration.
- Low-Noise Design: Pump-head and flow-path optimization helps reduce noise without sacrificing compactness.
- High Gas Tightness: Stress-optimized diaphragm and valve construction helps minimize unwanted gas leakage.
- Compact Construction: Small dimensions simplify integration into portable and space-constrained equipment.
- Flexible Mounting: Can be mounted in multiple orientations according to equipment-layout requirements.
- EPDM Diaphragm: Standard elastomer configuration is suitable for air and other compatible gases.
- EPDM Valves: Provide reliable gas-flow control in standard configurations.
- Chemical-Resistance Options: Alternative materials such as PTFE, FPM, FFPM, and other combinations can be specified for compatible corrosive gases.
- Clean Gas Path: Suitable for applications where oil contamination of the gas stream is undesirable.
- Application-Specific Configurations: Pressure, vacuum, motor, voltage, and material options allow selection according to the intended system.
