HR-3

High Recovery

  • Improves flow rates (tap pressure) through increased tank pressure

Take a look how the permeate pump works

 

In typical RO systems, performance decreases as tank pressure increases.  This limits most RO systems to approximately 60- 70% of line pressure in their tanks.  A Permeate Pump enhanced RO system can achieve up to 95% of line pressure without impacting system performance.  This provides stronger, more reliable flow rates at your tap and also helps meet the high minimum pressure requirements often required for coffee makers, ice machines, etc. 

Summary of Key Features

  • No electricity required, powered only by hydraulic energy normally lost to drain

  • Improves water quality by insuring membrane efficiency

  • Improves membrane life, prevents “TDS creep”

  • Decreases product tank “fill time” by up to 65% 

  • Reduces drain wastewater by up to 80% 

  • Increases product tank pressure (up to 95% of feed pressure)

  • For all membranes rated 10 - 120 Gpd

  • Effective for inlet water pressures as low as 30 PSI

  • Compact size for easy installation

Performance

PERFORMANCE - FILL RATE @ 60 PSI FEED
Product
Time to fill
Qty (ml) Tank (psi) With perm W/o pump
4989 ml 60 psi 1hr13min
4232 ml 40 psi
1hrs 42min
300 ml 60 psi 7 min
1047ml 60 psi 22.5 min.
1800 ml 40 psi
1.1 hrs.

Data shown in graph above shows strong advantage of Perm pump in tank pressure achieved, time to completely fill the tank, and total amount of water. Perm pump allows 50% greater tank pressure (60 psi vs 40 psi), 18% more water (4989mis vs 4232 ml), in 28% less time (1:13 min vs 1:42min).

The last three lines in the chart show a significant benefit for the Perm Pump in withdrawal of small amounts of water. A glass full (10.6 oz) takes 7 minutes to refill with a Perm system. 6 cups (36.9 oz), enough for a pot of coffee is replenished in 22.5 minutes with the Perm Pump. 1800 ml or 63.5 oz) must be withdrawn from a conventional system to allow the hydraulic shut off valve to reopen allowing the system to refill. It takes 62 min. to replenish 1800 mis, a 176% increase in time to refill.

PERFORMANCE - FILL RATE @ 30 PSI FEED
Product

2947 ml 24 psi 2hr10min
2636 ml 22 psi

300 ml 24 psi 15 min
1047ml 24 psi 35 min.
** 22 psi

Data shown in graph above shows strong advantage of Perm pump for low feed water pressures. Perm pump allows slightly more tank pressure (24 psi vs 22 psi), 12% more water (2947mis vs 2636 ml), in less than half the time (2:10 min vs 4:41min). The last three lines in the chart shows a huge benefit for the Perm Pump in withdrawal of small amounts of water. A glass full (10.6 oz) takes 15 minutes to refill with a Perm system. 6 cups (36.9 oz), enough for a pot of coffee is replenished in 35 minutes with the Perm Pump. No data was taken to determine quantity that must be withdrawn from a conventional system to allow the hydraulic shut off valve to reopen allowing the system to refill, although it was observed that the product tank pressure fell to 11 psi before refill commenced. It then took 4 hours 20 min. to completely refill the tank, or 800% increase in time to refill.
