This pump is designed to be installed before the Stealth-RO to boost the inlet pressure.
There needs to be at least 40 psi and up to 80 psi of inlet pressure for the Stealth-RO to function properly. People on wells and other situations of low pressure can benefit greatly from this pump.
It boosts the pressure significantly, allowing the Stealth-RO to run with higher flow and efficiency while having better TDS removal.
The pump is designed for long service life and runs very quietly.
