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.

The V-Flow Pump NV12-10S combines precision engineering with dependable performance, making it a trusted choice for a wide range of water handling needs.

Installation Manual

Installation Instructions for V-Flow Pump NV12-10S

1. 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.
2. 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.
3. Piping Connections:
   • Ensure piping matches the pumps 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.
4. Electrical Connection:
   • Have a certified electrician verify that the electrical supply matches the motors specifications (2 HP, single-phase).
   • Ensure proper motor wiring and confirm counterclockwise rotation when viewed from the motors rear.
   • If rotation is incorrect, consult the motors wiring instructions for correction.
5. 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.
6. 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.
7. 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.
