Product overviewManufacturer material
Product Description
The V-Flow Pump NV12-10S is a high-efficiency, ten-stage vertical booster pump designed for industrial, commercial, and agricultural applications. Its vertical, in-line design saves valuable floor space while delivering reliable, consistent performance in demanding environments.
Motor Options
-
Single-Phase Motor
- Ideal for locations without three-phase power
- Provides the same flow capacity and pressure as the three-phase model
- 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, water treatment, irrigation, sprinkler systems, hot and cold water circulation, and general water boosting applications.

Installation & maintenanceManufacturer material
Installation Instructions for V-Flow Pump NV12-10S
-
Preparation:
- Inspect the pump and motor for any visible damage during shipping. Report any damage to the carrier or dealer immediately.
- Ensure the installation site is level, stable, and provides adequate space and ventilation for motor cooling and servicing.
- Verify that the pump model matches the system requirements and intended application.
-
Mounting the Pump:
- Secure the pump base to a solid, flat surface to minimize vibrations during operation.
- Align and support the suction and discharge piping to prevent undue strain on the pump.
- Install isolation valves on both the suction and discharge sides for easy maintenance and servicing.
-
Piping Connections:
- Ensure piping matches the pump’s 2" ANSI 150# flanged connections.
- Install appropriate gaskets to prevent leaks and ensure unobstructed flow.
- Remove any protective covers or caps from the flanges before installation.
- For hot water systems, include 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 (2 HP, single-phase).
- Ensure proper motor wiring and confirm counterclockwise rotation when viewed from the motor’s rear.
- If rotation is incorrect, consult the motor’s wiring instructions for correction.
-
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 check for smooth operation without unusual noise or vibration.
- Gradually open the discharge valve to achieve desired operating conditions.
-
Safety Precautions:
- Never operate the pump without water to avoid damage to internal components.
- Replace coupling guards after installation to ensure operator safety.
- Ensure the pump is properly grounded and all connections are secure before starting.
