High Recovery
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.

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be withdrawn from a conventional system to allow the hydraulic shut off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.

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 No data was taken to determine quantity that must be withdrawn from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.
