Installation Instructions for V-Flow Pump NV25-7S Vertical Pump
-
Preparation:
- Inspect the pump and motor for any visible damage during shipping. Report any damage to the carrier or dealer.
- Ensure the installation site is level, stable, and provides adequate ventilation for motor cooling and servicing.
- Verify that the pump model matches the system specifications and intended application.
-
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 excessive strain on the pump.
- Install isolation valves on both the suction and discharge sides for easier maintenance and servicing.
-
Piping Connections:
- Ensure piping matches the pump’s 1.5" ANSI 150# flanged connections.
- Install proper gaskets to prevent leaks, ensuring they do not obstruct flow.
- Remove 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).
- Ensure proper motor wiring and confirm counterclockwise rotation when viewed from the motor’s rear.
- If rotation is incorrect on a three-phase motor, reverse any two leads 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 to avoid damage to internal components.
- Replace coupling guards after installation to prevent injuries.
- Ensure the pump is properly grounded and all connections are secure before starting.
