Product Overview
The JSG07WB is a compact 12V or 24V brushless diaphragm liquid pump designed for clean-water pressurization and OEM liquid transfer systems. It delivers up to 1 L/min maximum flow and 10 bar maximum pressure, with a working flow of at least 0.5 L/min at 5 bar.
Its brushless DC motor provides up to 3,000 hours of service life, while the self-priming and oil-free diaphragm structure supports reliable integration into water purification, beverage equipment, compact spraying systems, and customized liquid delivery devices.
The standard configuration uses an EPDM diaphragm and valves. An optional FKM configuration is available for projects requiring different chemical or temperature resistance. Final compatibility must be confirmed according to the liquid composition, concentration, temperature, pressure, and operating time.

Which Media and Materials Is This micro diaphragm liquid pump Compatible With?
The JSG07WB uses standard EPDM diaphragms and valves for clean water, with optional FKM available for liquids requiring different chemical or temperature resistance. Final compatibility should be confirmed through sample testing based on the liquid composition, concentration, temperature, pressure, and operating time.
Standard EPDM
| Media Type | Recommendation |
| Clean water | Standard application |
| Purified water | Suitable after system verification |
| Mild water-based liquid | Confirm additives, concentration, and temperature |
Enhanced FKM
| Media Type | Recommendation |
| Selected chemical liquids | Confirm exact chemical composition |
| Fragrance-containing liquids | Sample testing required |
| Disinfectant-containing liquids | Confirm concentration and temperature |
| Liquids requiring different temperature resistance | Confirm all wetted materials |
What Applications Is This micro diaphragm liquid pump Suitable For?
1.Water Purification and Pressurization Systems
The JSG07WB can support RO booster systems, filtration equipment, point-of-use water devices, and compact pressurized water circuits. System designers should confirm the working pressure, filter resistance, tubing size, inlet filtration, and required flow under load.
2.OEM Liquid Delivery and Spraying Equipment
The pump can also be integrated into beverage equipment, compact cleaning systems, spraying modules, atomization equipment, and customized liquid delivery devices. EPDM or FKM should be selected according to the actual liquid and operating conditions.
How Do I Choose the Right Version of This Pump?
1.Confirm the Required Working Point
Select the pump according to the required flow at the actual system pressure, not only the maximum flow or maximum pressure.
2.Choose the Correct Voltage
Select the 12V or 24V version according to the equipment power supply, available current, wiring, and control system.
3.Select EPDM or FKM
Use EPDM for clean water and confirmed mild water-based liquids. Consider FKM when different chemical or temperature resistance is required.
4.Check the Complete System Resistance
Tubing, filters, nozzles, valves, connectors, and liquid viscosity can reduce the actual working flow.
5.Confirm Installation and Duty Cycle
Check the available space, mounting direction, operating time, vibration requirements, and continuous or intermittent working conditions.
Real Project Cases Using This DC Diaphragm Water Pump
Case 1: 24V JSG07WB for an RO Water Purifier
A customer needed a compact pump for a household water purifier system. The system required stable pressure and reliable liquid transfer within a limited internal space. We recommended a 24V high-pressure DC diaphragm water pump based on the required working pressure of 5.5 bar and flow range of 0.8 L/min. After testing with the customer’s filter and tubing system, the pump achieved a stable output of 5.8 bar and met the customer’s pressure requirement.
Case 2: 12V JSG07WB brushless diaphragm liquid pump
A beverage equipment customer required a compact pump for intermittent water delivery inside a small dispensing machine. We selected a 12V JSG07WB and confirmed the diaphragm material according to the customer’s liquid composition. The connector direction was adjusted to match the internal tubing layout, and the complete liquid circuit was tested under the actual filter and outlet resistance before production.
