Tips & Care Instructions

Mount the pump securely using rubber grommets to reduce vibration noise during operation
Ensure 12V DC polarity is correct before connecting — reverse polarity will damage the motor
Flush the pump with clean water after pumping any chemical solution to extend diaphragm life
Use 10mm ID hose for inlet and outlet connections to match the barb fitting diameter
Install an inline filter before the pump inlet to prevent debris from damaging the diaphragm
The pump self-primes up to 1.5 metres, so position it within this distance of the water source
