100,000 cycles
12 kg hammer impact — 100,000 hits per protocol.
12 kg leak
Every pump, hydrostatic, no drip before it ships.
Curve capture
Imported sensors store flow and pressure per serial.
Applications
Where the water actually moves.
Household RO
50–800G under-sink and tankless. Self-priming when the tank sits high.
Commercial & boilers
800–1600G, brushless duty, office and restaurant recovery.
Tea / coffee / micro
38M and 801/802/901 loops that sit beside the RO core.

How to choose an RO booster pump by GPD
Match membrane flux first, then voltage and duty. A 400G tankless kitchen is not a 75G tank system with a louder motor.
