Canned Vertical Turbine pump Installation (Type VS6)

LIFTING DEVICE SAFETY

• Use mechanical lifting devices to lift heavy or awkward components.

• Lifting devices must be in good condition, certified, and tagged.

• Lifting devices of adequate capacity must be used whenever they are required.

• Personnel must never work under suspended loads.

LIFTING POINT SAFETY

Check lifting lugs are in suitable condition for lifting, before lifting pump parts.

1. Position the lifting equipment so it will center over the suction vessel mounting flange.

Clean the suction vessel and piping of all abrasive particles and loose debris before installation, to avoid any damage to the pump.

2. Clean the suction vessel mounting flange, oil lightly, and position the gasket. Clean the pump mounting flange and oil lightly.

• All machined surfaces are coated with rust preventative prior to shipment. This must be

completely removed along with any paint overspray or rust which might be there on the

machined faces.

• The faces must be scraped and wire brushed first.

• Use fine emery cloth to remove any stubborn spots.

can pumps have the suction nozzle located on the discharge head or the suction vessel.

3. Clean the pump discharge flange (and suction flange wherever applicable).

Be particularly careful not to damage any piping which may extend down along the column

and/or bowl assembly. This piping (when used) must not be crushed. If damaged, remove

and replace it.

4. Lift the pump, mount the strainer if required and lower slowly into the suction vessel. Guide the pump as it is being lowered and watch for any obstructions or binding of the pump. Stop lowering the unit when still a few inches off the mounting flange.

5. Rotate the pump until the discharge flange faces the proper direction for alignment with piping. Align the mounting flange bolt holes.

• discharge heads have both suction and discharge flanges. Therefore, it is important to make sure that the suction piping is connected to the suction side of the pump.

• A flow arrow is located on the side of the suction pipe to help identify the correct orientation.

• Figure 5-2 is provided to enable field identification in case the flow arrow is not visible.

6. Check the mounting flange gasket to ensure it is in the correct position. Some pumps may be supplied with O-rings in lieu of a gasket.

7. Slowly lower the pump onto the mounting flange.

8. Install the mounting bolts or nuts. Do not tighten at this stage.

CAUTION：EQUIPMENT DAMAGE

Excessive nozzle loads must not be imposed on the pump. All piping must be carefully aligned and supported to prevent excessive nozzle loads.

It is strongly recommended that flexible connectors (dresser couplings or equivalent) be installed in the piping immediately adjacent to the pump.

9. Connect the system piping to the pump, if required, shift the pump slightly on the mounting flange to facilitate alignment.

WARNING：

• Always ensure proper tightening of all piping connections to the pump.

• Ensure the required gaskets and/or o-rings are installed.

• Poor connections may result in leakage.

• Leakage of hazardous or high pressure pumpage may result in personnel injury.

10. Tighten the discharge (and suction, if applicable) flange bolting. Ensure that the flanges mate face to face without applying excessive force.

11. Tighten the mounting flange bolting.
