Your Key Benefits


Increased production rate of your R.O. system

Better purification

Less water waste

Longer membrane and pre-filters service life

Ideal Upgrade Option for R.O. Systems Medal

They are ideal companion devices and an upgrade option for your existing R.O. machine and let you save on various costs related to its everyday use and maintenance.

Perfect Companion Device for R.O. Systems Medal

LED indicators on the front panel allow to easily understand what the state of your R.O. unit is.

Ever wondered whether your tank is full or empty? No more guess!

Key Features


Automatic flush valve prevents the scale and debris buildup on the membrane outer surface: for peak performance and healthier membrane.

Powerful pump boosts the pressure to radically improve your R.O. machine’s daily production rate, membrane’s rejection rate and recovery rate. It’s a totally new level of performance and effectiveness.

Prolongs the membrane and pre-filter(s) service life due to increased recovery rate.

Fully automatic operation, no service necessary: plug and forget.

LED indicators: for easier reading of the R.O. system's state.

Split, flexible installation possible where needed: install the pump box up to 50 feet away from the R.O. unit itself. Useful for the situations like lack of space or lack of electrical outlet under the sink.

Allows full separation of electrical components from the membrane and filters of the main R.O. unit that makes the regular servicing of your R.O. machine both easy and safe: no need to worry about electrical valves and wires while changing your water filters or membrane.

Inlet water lack protection, idling protection.

Quick-fittings for easier tube connections.

Low noise.

Low power consumption.

Compact and modern design.

Connect the Pump Bot as shown.

Important: if your R.O. machine includes 4-way shut off valve (control valve), flow restrictor, manual flush valve remove them on the R.O. system itself. The unit’s internal components will be used to provide the same or enhanced functionality.

After the installation use your R.O. system as you normally would. If your tank is not full the unit will turn on automatically and fill it up with filtered water. Then it will flush the membrane and shut off automatically. If you open the faucet and take some filtered water from the tank the pump will turn on automatically to refill the tank again.

Upgrade to Direct Flow R.O.*

With X855 model you may even turn your old system into a modern direct flow high-production R.O. machine with unbeaten water freshness, efficiency and further cost savings.

How to Upgrade to the Direct Flow R.O. System with the Prio® Pump Box X855 Chart

Connect the Pump Bot as shown.

Please note: you need a high-production membrane for the direct flow scheme to work acceptably. Minimum recommended production rating of the R.O. membrane is 300gpd.

Important: if your R.O. machine includes 4-way shut off valve (control valve), flow restrictor, manual flush valve remove them on the R.O. system itself. The unit’s internal components will be used to provide the same or enhanced functionality.

After the installation use your R.O. unit as you normally would. To get pure water, just open the filtered water faucet. The pump will turn on automatically and will produce the filtered water flow in real time until you close the faucet. At the end of each water production cycle the membrane will be flushed, and then the system will shut off automatically.

Technical Data

Operating Requirements:

  • Minimum inlet water pressure: 7.25 psi (0.05 MPa)
  • Maximum inlet water pressure: 61 psi (0.42 MPa) / 80 psi (0.55 MPa) when used together with select Prio® R.O. units
  • Minimum water temperature: 41 °F (5 °C)
  • Optimal water temperature: 59–77 °F (15–25 °C)
  • Maximum water temperature: 95 °F (35 °C) / up to 105 °F (40.5 °C) short-term
  • Ambient air temperature: 41–105 °F (5–40.5 °C). Indoor use only.
  • Water source: tap water supply, chlorinated or non-chlorinated, bacteriologically safe
  • Supply water pH range: 4.0-11.0
  • Supply water turbidity: <1 NTU
  • Supply water components: Hardness (CaCO3) <180 mg/L (<10.5 gpg), Iron <0.1 mg/L, Manganese <0.05 mg/L, Hydrogen Sulfide 0.00 mg/L
  • Maximum supply water TDS: 1000 ppm
  • Electrical input: AC 100-240V 50/60 Hz
  • Electrical plug: US Type A / Europlug CEE 7/16
  • Maximum length of the line between the unit and the membrane (“split installation”): 50 ft (15 m) (purchase of extra tubing may be required)
  • Tubing: ¼”

Weight and Size:

  • Size (WDH), body only, excluding protrusions: 8.74 x 4.80 x 12.44” (222 x 122 x 316 mm)
  • Weight, without water and tubing:
    • 8.2 lbs (3.7 kg) for X845;
    • 8.6 lbs (3.9 kg) for X855

Performance Guidelines:

Performance of the appliance such as pressure boost or flow rate of the connected R.O. unit is highly dependent on local conditions (inlet water pressure, temperature and TDS, R.O. membrane type and flow rating, R.O. unit type and its design specifics) and R.O. system use pattern.

  • Typical pressure boost (ΔP, extra pressure built upon the inlet pressure) is up to 50 psi (0.34 MPa) for 50-100 GPD R.O. membrane for X845, and up to 100 psi (0.69 MPa) for 150-500 GPD membrane for X855. For example, the higher the GPD rate of the membrane attached or the higher the water temperature the lower is an actual pressure boost for a given setup but the higher the output flow rate in working mode. Typically, in working mode outlet water pressure reaches 80-110 psi for X845 and 110-160 psi for X855 depending on local conditions and membrane used.
  • Drain water flow restrictor: 300 cc (ml/min) nominal, up to 450 cc in working mode, open flow in flush mode.
  • Auto-flush duration: 18±5% s
  • Idling protection: 120 minutes (the unit will shut-off the pump and goes into ‘reset required’ mode if working mode continuous duration reaches 2 hours without interruption)
