Product Description
The V-Flow Pump NV120-3-2SS is a high-efficiency, ten-stage vertical booster pump designed for industrial, commercial, and agricultural applications. Its vertical, in-line design saves space while delivering reliable performance in demanding environments.
Motor Options
-
Single-Phase Motor
- Ideal for locations without three-phase power
- Same flow (up to 120 GPM) and pressure (up to 232 PSI) as three-phase models
- Slightly lower electrical efficiency and better suited for lighter duty cycles
-
Three-Phase Motor
- Standard for commercial and industrial sites
- Higher electrical efficiency and smoother continuous operation
This pump is well-suited for reverse osmosis, washing systems, water treatment, power plants, boiler systems, water boosting, irrigation systems, sprinkler systems, and hot and cold water circulation.
The V-Flow Pump NV120-3-2SS combines precision engineering and dependable performance, making it a trusted choice for a wide range of water handling needs.

Installation Instructions
Installation Instructions for V-Flow Pump NV120-3-2S Vertical Pump
-
Preparation:
- Inspect the pump and motor for damage during shipping. Report any visible damage to the carrier or dealer.
- Ensure the installation site is level, stable, and provides sufficient space and ventilation for motor cooling and servicing.
- Verify that the pump model matches the system requirements.
-
Mounting the Pump:
- Secure the pump base to a solid, flat surface to prevent vibrations during operation.
- Align and support the suction and discharge piping to avoid strain on the pump.
- Install isolation valves on both the suction and discharge sides for easier maintenance.
-
Piping Connections:
- Ensure piping matches the pump’s 3" ANSI 150# flanged connections.
- Install gaskets to prevent leaks, ensuring they do not obstruct flow.
- Remove protective covers or caps from the flanges before installation.
- For hot water applications, install a bleed valve in the discharge line to relieve pressure during maintenance.
-
Electrical Connection:
- Have a certified electrician verify that the electrical supply matches the motor’s specifications (10 HP, three-phase).
- Ensure proper motor wiring and confirm counterclockwise rotation when viewed from the motor’s rear.
- If the rotation is incorrect, reverse any two leads on a three-phase motor to correct it.
-
Priming the Pump:
- Remove the fill plug and use a funnel to fill the pump casing with water.
- Open the vent plug to allow air to escape as the pump fills with water.
- Re-seal the vent plug and fill plug once a steady stream of water flows from the vent.
-
Initial Testing:
- Open the suction valve fully and partially open the discharge valve.
- Apply power to the motor and monitor for smooth operation without noise or vibration.
- Gradually open the discharge valve to achieve desired operating conditions.
-
Safety Precautions:
- Never operate the pump without water, as it can cause damage to internal components.
- Replace coupling guards after installation to prevent injuries.
- Ensure the pump is properly grounded and connections are secure before starting.
