Troubleshooting Guide
Pump does not run with power connected: Check that all wiring connections at the rear of the motor are secure and properly seated.
Low spray volume or reduced pressure: Inspect the pump chamber for debris blockages. Verify that the motor bracket screws are tight. Ensure the inlet and outlet valves are installed in the correct orientation (they must not be reversed).
Pressure drops after extended use (6–12 months): Tighten the motor bracket screws, and rotate or replace the small diaphragm pieces inside the pump cavity to restore full performance.

Frequently Asked Questions
Q: What voltage does this diaphragm pump require, and can it run on a solar battery?
A: This pump operates on 12V DC, which falls within the low-voltage range (below 75V DC). It is fully compatible with standard 12V car batteries, portable power stations, and solar energy storage batteries — making it an excellent choice for off-grid agricultural or remote applications.
Q: Is this pump suitable for spraying pesticides or fertiliser solutions?
A: Yes. This self-priming diaphragm pump is designed for agricultural spraying, including pesticide and fertiliser liquid transfer. Always flush the pump with clean water after use with chemical solutions to preserve pump life and performance.
Q: Does the pump require priming before first use?
A: No manual priming is required. The self-priming diaphragm design means the pump can draw liquid automatically from the source without needing to be pre-filled, making setup quick and hassle-free in the field.
Q: What is the maximum pressure this pump can achieve?
A: This pump delivers a maximum pressure of 6.0 BAR (approximately 87 PSI), making it suitable for high-pressure spraying applications including fine misting nozzles, pressurised cleaning, and irrigation systems.
