Product Overview
The JSG385HPW-5 is an 83 g self-priming DC liquid pump for OEM water transfer, rinsing, and filling modules. Both DC voltage versions, 12 V and 24 V, come with two-wire (2P) and three-wire (3P) options, so you can match the pump to the power supply and harness.
First, define the inlet lift, outlet backpressure, and volume required per cycle. Because the datasheet lists room-temperature water flow and delivery head separately, verify the flow at your required head with the actual plumbing.
Core Selling Points of This Self-Priming DC Liquid Pump
- Self-Priming Lift Greater Than 2 m
For example, when the reservoir sits below the pump, verify priming at the lowest water level. - 2 L/min Room-Temperature Water Flow
Use this specification as a starting point when sizing a small transfer, rinse, or filling module. - 30 m Delivery Head Specification
An elevated outlet or restrictive plumbing can reduce flow, so measure it at the required delivery head. - Four Voltage and Wiring Versions
Choose 12 V or 24 V DC first. Then match the two- or three-wire version to your equipment. - Compact 83 g Pump
The drawing shows an 82.05 mm pump length. In addition, allow room for tubing and wiring when laying out the enclosure.

What Are the Dimensions and Installation Details?
The drawing shows an 82.05 ± 0.30 mm length, a pump head measuring 35.4 ± 0.3 mm wide by 33.5 ± 0.3 mm high at the indicated points, and two ports marked Ø5.4 ± 0.1 mm. The leads are 290 ± 10 mm long and use UL 1007 24 AWG wire. In addition to the pump body, allow room for the tubing bend and rear wiring.

Which Media and Materials Is This DC Liquid Pump Compatible With?
| Medium or condition | Selection guidance |
|---|---|
| Room-temperature water | The medium used for the specified flow test. |
| Water at another temperature | Provide the actual liquid temperature for review. The 0–50 °C specification refers to ambient conditions. |
| Treated water or cleaning solutions | Provide composition, concentration, and temperature for a wetted-material review. |
| Potable water | Request model-specific material and compliance documentation for qualification. |
What Applications Is This Self-Priming Mini Water Pump Suitable For?
- Reservoir-to-Module Transfer. First, check priming at the lowest water level. For a machine with a two-wire harness, start with a 2P version.
- Intermittent Rinsing. If the machine already has a 24 V supply and a two-wire harness, start with the 24V 2P version. Then measure the water delivered per cycle through the actual nozzle.
- Small Tank Filling. For a two-wire 12 V system, evaluate the 12V 2P version. Since the elevation difference and outlet fittings affect flow, include both when measuring fill time.
How Do I Choose the Right 12V or 24V Water Pump Version?
- Match the Supply. First, choose the 12 V or 24 V version. Then check the voltage at the pump during startup and operation.
- Match the Harness. Choose 2P for a two-wire connection. If your project calls for 3P, confirm the intended wiring before integration.
- Define the Working Point. Specify the required flow at the actual delivery head or backpressure, including the inlet lift.
- Check the Duty Cycle. Finally, test with your planned ON and OFF times and verify flow and current in the finished circuit.
Practical Configuration Examples for This DC Liquid Pump
Configuration 1 — 24 V Rinse Module. A system with a 24 V supply and a two-wire harness can start sample evaluation with the 24V 2P pump. Install the intended valve and nozzle, then record the rinse volume and current during each programmed cycle.
Configuration 2 — 12 V Reservoir-to-Tank Transfer. For a 12 V system with a two-wire harness, evaluate the 12V 2P version with the reservoir at its lowest level. Once the final tubing and outlet fittings are in place, measure the time to prime and fill the tank.
