  • Page 27 4.1 Pre-installation 4.1.3.17 V-Belt Alignment Although alignment is not as critical in V-belt drives as in others, proper alignment is essential for long belt and sheave life. First, make sure that drive shafts are parallel. The most common causes of mis- alignment are non-parallel shafts and improperly located sheaves.

    When to install a minimum-flow orifice You can size and install a minimum-flow orifice in a bypass line in order to prevent bypassing excessive flows. Consult your ITT representative for assistance in sizing a minimum-flow orifice. When a minimum-flow orifice is unavailable Consider an automatic recirculation control valve or solenoid-operated valve if a constant bypass (mini- mum-flow orifice) is not possible.
  • Page 29 Refer to Hydraulic Institute Standards general guideline for sump design. 4.1.6.1 Valves ITT does not recommend the use of a valve on the suction line EXCEPT: a) In case where positive suction heads are present in the line EXCEPT: b) Where it is possible for a positive head to develop due to flooding conditions.

  • Page 30: Discharge Piping

    4.1 Pre-installation Gate and check valves may be used on the discharge side, but it is not necessary in low dis- charge head applications. It is recommended to use a throttling valve and check valve in the discharge line to protect the pump from excessive shock or water hammer and reversed rotation when pump is stopped.

    5.5 Impeller Running Clearance If pump is oil mist lubrication, check that the mist is flowing properly prior to starting pump. Use good grade SAE #30 non-detergent motor oil. Units are shipped without oil but should be checked before starting. Fill seal cavity with oil through hole provided on top of bearing housing nearest pump casing, until you see oil through hole opening.
