CSV1A
Pump- Flow
- 1 to 25 gpm
- Pressure
- Adjustable 15–150 psi
- Connection
- Dual threaded — 1" female NPT and 1¼" male NPT; two ½" side ports for pressure switch, gauge or relief valve; one ¾" bottom port for the pressure tank
- Best for
- Holds constant pressure by throttling the pump to match demand, instead of cycling it on and off. That means a small tank and no VFD — far less to go wrong and far cheaper than variable-speed. Inlet-to-outlet pressure difference must stay within 125 psi
