3 Product Description 3 Product Description 3.1 General description The Series e-90 in-line mounted centrifugal pump is a close-coupled pump. This pump is available for pipe sizes that range from 1 in to 3 inches. Pump application WARNING: This product can expose you to chemicals including Lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to: www.P65Warnings.ca.
4 Installation 4 Installation 4.1 Preinstallation Precautions WARNING: • When installing in a potentially explosive environment, make sure that the motor is properly certified. • You must ground (earth) all electrical equipment. This applies to the pump equipment, the driver, and any monitoring equipment. Test the ground (earth) lead to verify that it is connected correctly. NOTICE: Supervision by an authorized Xylem representative is recommended to ensure proper installation.
4 Installation Mode of discharge You can install this pump to discharge either vertically or horizontally. The arrow on the pump body must point in the direction of the flow. You can install the pump with the motor either vertical or horizontal. Do not install the motor below the pump body. 4.1.2 Piping checklist WARNING: • The heating of water and other fluids causes volumetric expansion. The associated forces can cause the failure of system components and the release of hightemperature fluids.
4 Installation Check Explanation/comment Check that new flange gaskets are installed between the flanges of the pump body suction and discharge pipes. Make sure that these gaskets are clean and grease-free. Suitable fasteners for this connection are supplied in the Xylem fastener pack. Apply a torque of 8 to 11 ft. lbs (11 to 15 Nm) to each of the flange bolts. Checked 4.1.3 Typical installation 11 12 10 3 9 2 13 5 8 4 1 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.
5 Commissioning, Startup, Operation, and Shutdown 5 Commissioning, Startup, Operation, and Shutdown 5.1 Preparation for startup WARNING: • Failure to follow these precautions before you start the unit will lead to serious personal injury and equipment failure. • Do not operate the pump below the minimum rated flows or with the suction or discharge valves closed. These conditions can create an explosive hazard due to vaporization of pumped fluid and can quickly lead to pump failure and physical injury.
5 Commissioning, Startup, Operation, and Shutdown 5.2 Lubrication requirements These pumps are permanently lubricated. 5.3 Prime the pump CAUTION: Do not run the pump dry. Make sure that the pump body is full of liquid before startup. If the system does not automatically fill the pump body with liquid, then you must manually prime the pump. 1. Loosen the vent plugs on the pump body. 2. While venting the air from the pump body, rotate the pump shaft a few times by hand. 3.
5 Commissioning, Startup, Operation, and Shutdown 5.5 Pump operation precautions General considerations CAUTION: • Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the suction side since this can result in decreased performance, unexpected heat generation, and equipment damage. • Do not overload the driver. Driver overload can result in unexpected heat generation and equipment damage.
6 Maintenance 6 Maintenance 6.1 Disassembly 6.1.1 Disassembly precautions This manual clearly identifies accepted methods for disassembling units. These methods must be adhered to. WARNING: • Make sure that the pump is isolated from the system and that pressure is relieved before you disassemble the pump, remove plugs, open vent or drain valves, or disconnect the piping. • Always disconnect and lock out power to the driver before you perform any installation or maintenance tasks.
6 Maintenance WARNING: Pressurized device. Make sure that the internal pressure is relieved before you continue. 11.Remove the volute capscrews and remove the pump assembly from the volute. 6.1.3 Typical cross section 1 13 2 6 6 12 3 4 9 8 5 11 7 14 10 10 1.

6 Maintenance NOTICE: These seal assemblies consist of a stationary seal insert assembly and a rotating seal assembly. Each of these components must be replaced when you replace the mechanical seal. Never replace individual components separately. 4. Grab the OD of the seal head assembly and remove. Remove the four cap screws that hold the bracket to the motor and remove the bracket. Push the cup-mounted seal seat out of the bracket with a small screwdriver. 5.
6 Maintenance The seal head assembly is a unitized design and should not be disassembled. 4. Clean the motor and impeller, and jamnut threads. . Apply Loctite 7471 Primer to the threads of the jamnut. Allow to dry. Apply a small amount of Loctite Retaining Compound 609 or 680 to the threads. Care must be used when applying Loctite so that it does not get on surrounding areas. 5. Screw the impeller onto the motor shaft.
