Typical Surface Pressure Boosting Application
The above drawing illustrates how a typical surface mounted pump system should be arranged for a pres -
sure boosting application.
1.
Water Supply
2. Check Valve
3. Ball Valve
4. Pressure Relief Valve: Pressure relief valve must be able to pass full pump flow at 100 PSI.
5.
Pressure Tank
. Refer to “Minimum Pressure Tank and Supply Pipe Sizing” on page 13 .
6. Pressure Gauge
7.
Pressure Transducer or Sensor:
Locate within 5 feet (1.5 m) of pump discharge. Install in a vertical
position.
8.
UT3P Drive
9. Power Supply from Circuit Breaker . Single phase, 208/230 VAC +/- 10%.
10.
Power to Motor:
Three-Phase 230 VAC.
11. Optional Bypass: For system maintenance.
IMPORTANT:
If the pump is equipped with a built-in pressure switch, the power wires from the drive must
bypass the pressure switch and connect directly to the motor.
Risk of bodily injury or property damage.
• Pumps can develop very high pressure in some situations. Always install a pressure relief valve able
to pass full pump flow at 100 psi.
• Install the pressure relief valve near the pressure tank and route to a drain capable of full system flow.
