Pumps Without Standard Motor; Start-Up; Priming - FPS VR Serie Manual De Instrucciones

WARNING: Avoid any contact between the electric cables and the pipes or other parts of the pump.
Carefully insulate cables from damp conditions.
If necessary, the motor may be rotated on its axis to facilitate accessibility for maintenance personnel. For all
versions of the pump with motor of rated power less or equal to 5.5 hp (4kW), first remove the coupling safety
casings to access the motor mounting screws (Fig. 15). For all other versions, the motor mounting screws are easily
accessible. In this case, it will be necessary to unscrew the mounting screws of the motor on the pump, turn the
motor in its place, and fix the screws again (Fig. 16).
WARNING: Having turned the motor and fixed the mounting screws, replace the safety casings where
necessary; failure to observe these instructions may cause personal injury.
Electric motors can generally run with a power voltage having a tolerance of:
motor 50 Hz, single-phase, 230 V +/-10
motor 50 Hz, three-phase, 230/400 V +/-10
motor 50 Hz, three-phase, 400/690 V +/-10
motor 60 Hz, three-phase, 220/380 V +/-10
motor 60 Hz, three-phase, 265/460 V +/-10
motor 60 Hz, three-phase, 460 V +/-10
Use standard power cables with 3 connections (2 + earth) for the single-phase versions and with 4 connections (3
+ earth) for the three-phase versions.

5.4.3 Pumps Without Standard Motor

• Use only dynamically balanced motors (IEC 60034-14; NEMA MG 1-7.8) and with normal vibration grade (A)
• Use only single- or three-phase motors whose size and power are in compliance with European and NEMA
standards, with IP55 protection rating and insulation class F or higher
• Please refer to the technical specifications to choose the correct motor size
• Check that the coupling surface is flat and even and that the screws are fixed and the alignment exact
• Before starting up the motor, turn the rotor by hand and check for any sounds of abrasions and/or friction
• The motor must be equipped with keyed joint
• For use and connections, refer to the relative "Installation Instructions" manual

6. START-UP

WARNING: Pay attention to discharged liquid so that it cannot cause damage to people or things. The
motor protectors can cause an unexpected restart of the motor, which may cause serious personal injury.
Never start up the pump without the coupling safety casings correctly installed.
WARNING: During operation the external surfaces of the pump and the motor could exceed (40 °C) 104 °F
if the pumped liquid is not at ambient temperature. Do not touch the unit without proper protection. Do not
put combustible material near the pump.
WARNING: The electric pump must NOT be started without prior filling. Its dry use may irreparably
damage the mechanical seal.

6.1 Priming

Case with liquid level above the pump (positive suction head Fig. 6-B)
• Close the delivery valve (Fig. 6-8).
• Partially unscrew the pin on the filling cap (Fig. 14-A-1 or Fig. 14-B-1).
• Open the inflow gate valve (Fig. 6-4) to allow the liquid to enter; wait until the water comes out of the side
hole of the cap.
• Tighten the pin of the filling cap.
