RO BOOSTER PUMP SYSTEM
Installation and Operation Instructions
The SHURflo Reverse Osmosis (RO) Booster Pump System enables most RO filtration units to be used anywhere
there is electrical power and water. The system was developed for areas where the average incoming water
pressure may be below 40 psi., or even from a non-pressurized source (tank). The booster pump maintains a high
RO feed water pressure, ensuring a consistent production of high quality RO water. The system includes an
boo
accumulator tank pressure switch, which turns off the
the system and minimal connections allow it to be easily installed under a sink. Quiet and safe, SHURflo RO
Booster Pump Systems will provide years of service.
♦
85 Series "High Flow" pumps are for RO filtration units that produce between 35–100 GPD
CAUTI
85 Series RO Booster Pump Systems MUST be used in conjunction with RO filtration units rated to
ON:
p
roduce at least 35 GPD Failure to do so may result in excessive pressure
damage to RO membrane, filter housings, and possible premature wear to the booster pump.
♦
70 / 80 Series "Low-Flow" pumps are for RO filtration units that produce up to 35 GPD The 70-121 does not
require regulated inlet water, internal bypass is not affected by inlet pressure.
INSTALLATION GUIDELINES
1. The enclosure/pump should be placed as close to the RO unit as possible. Located in an area that is dry, with
ambient temperatures between 40°–90°F

APPLICATION TIPS

A. RO feed water pressure from the pump is dependent upon restrictions within a particular RO filtration unit.
Nominal booster pump system pressure will be between 75–110 psi. [5–7.5 bar].
B. Re-check all water connections for leaks after the RO unit has completely filled the accumulator and the booster
pump shuts off.
C. In the event of a power failure, the drinking water system will operate on normal city water pressure. A lower
quantity and quality of water may be produced during this period. Once the power is restored, drain the reservoir
and allow the system to produce new supply of water.
D. The pump design permits brief periods of dry operation; however, extended dry operation will decrease its
performance/longevity.

1052 for further information regarding RO Booster Pump System, maintenance,
troubleshooting, and repair.
