50–800 GPD
Household RO
The market moved to 400G+ because people hate waiting on the tap. High-flow 502/605 and silent 605 exist for that shift — tankless recovery without a compressor scream.

Application map
One pump family. Six machines that actually sell.
800–1600 GPD
Commercial purifiers
Office islands, restaurant ice, factory tea rooms. Brushless 605 for machines that run all day. Dual-head when one chamber is not enough.

Intermittent high head
Boilers & dispensers
Hot tanks hate pulsation. Damping 605 plus imported wear seals cut service calls on water boilers and standing dispensers.

Tea-bar & coffee
A tea-bar is two pumps: RO core and a small transfer. 801/802/901 and 38M sit in the second envelope.

50–400 GPD + mix loop
Hydrogen water
502 hydrogen-mix keeps the same cabinet cutout as standard 502 so you do not retool the chassis.

Pressure over size
High-TDS markets
Export SKUs into high-TDS feed water need 505 / BL-HP — more PSI, same cabinet language.
