Especificaciones técnicas

  1. Construction

    2. Supply and install, as shown on the plans and specifications, Armstrong Series 4700 Vertical MultiStage pump. The pump shall have a continuously rising curve from minimum head to shut off condition and shall have a motor installed that is suitable for the full range of the published performance curve.

    • Models VMS-03, 05, 10 & 18: All hydraulic components shall be manufactured from Type 304 stainless steel.
    • Models VMS-32, 45 & 64: Manufactured from Type 304 stainless steel with cast iron casing.

      • The 316L stainless steel shaft shall be fitted with Tungsten Carbide intermediary bearing(s).

  2. Mechanical Seal

    3. The mechanical seal shall be suitable for the full pressure and temperature range of the pump and shall be fitted with Carbon rotating face and Silicon Carbide stationary face.

  3. Pedestal Bearing

    4. The motor pedestal shall be fitted with an integral thrust bearing on pumps where the motor is greater than 5 HP.

    The thrust bearing must be connected to the adapter and shaft in such a manner as to eliminate any transfer of pump axial loads to the motor, allowing standard NEMA design motors to be used.

  4. Connections

    5. The base mounted pump shall be assembled in a vertical shaft configuration with the suction and discharge connections being 180° in-line at the bottom.

    Suction and discharge connections shall have same size flanges with an ANSI 150 (250 or 300, as appropriate) rating.

  5. Motor

    6. Supply a standard NEMA design 2-pole motor with the electrical characteristics, efficiency level and enclosure as indicated on the drawings.
