  • Page 5: Introduction And Safety

    ITT Goulds pumps will provide safe, trouble-free service when properly installed, maintained, and operat- Safe installation, operation, and maintenance of ITT Goulds Pumps equipment are an essential end user responsibility. This Pump Safety Manual identifies specific safety risks that must be considered at all times during product life.

  • Page 6: Safety

    Trapped liquid can rapidly expand and result in a violent explosion and injury. ITT Goulds Pumps will not accept responsibility for physical injury, damage, or delays caused by a failure to observe the instructions for installation, operation, and maintenance contained in this Pump Safety Manual or the current IOM available at http://www.gouldspumps.com/literature.

  • Page 7: General Precautions

    Personal injuries will result if procedures outlined in this manual are not followed. ITT Goulds Pumps will not accept responsibility for physical injury, damage or delays caused by a failure to observe the instructions in this manual and the IOM provided with your equip- ment.
  • Page 8 1.4 General precautions Shaft alignment procedures must be followed to prevent catastrophic failure of drive components or unintended contact of rotating parts. Follow coupling manufacturer's coupling installation and operation procedures. WARNING Before beginning any alignment procedure, make sure driver power is locked out.
  • Page 9 1.4 General precautions WARNING The pump may handle hazardous and/or toxic fluids. Observe proper decon- tamination procedures. Proper personal protective equipment should be worn. Precautions must be taken to prevent physical injury. Pumpage must be han- dled and disposed of in conformance with applicable environmental regula- tions.

  • Page 16 4.1 Pipework • Flange seals must not extend into the interior of the pipework. • Clean the pipework prior to pump installation. • Support the pipelines so as to prevent distortion of pump components. • Avoid rough cross-section transitions and sharp bends. •...
  • Page 17 4.1 Pipework • In order to prevent clogging, it is recommended that the customer provide a sedimenta- tion tank or a larger flushable fine strainer upstream from the pump. Design: Conical strainer with perforated plate support body with external fine screen, mesh size 0.5 mm, of corro- sion-resistant material.

Additional line Shut-off valve Shut-off valve (vacuum tight) Figure 5: Vacuum operation Discharge line For flow control, install a shut-off valve as close to the pump nozzle as possible. It is recommended that a non-return valve be installed between pump nozzle and shut-off valve, thus protecting the pump against reverse rotation and also the pump and the foot valve against water hammer that may occur in the event of sudden shut-down.
  • Page 20 4.1 Pipework • A non-return valve should be installed in the minimum flow nozzle or the minimum flow line. • For repair or overhaul work on the pump or the bypass non-return valve, a shut-off valve must be installed in the minimum flow line (c). a.
