Armstrong Fluid Technology Vertical In-Line Pumping Unit IVS 4380

Lubrication is not required. There are no bearings in the pump that need external lubrication service.

Large Design Envelope 4300 units are installed with a shaft bushing located beneath the impeller that is lubricated from the pump discharge.

Follow the lubrication procedures recommended by the motor manufacturer. Many small and medium sized motors are permanently lubricated and need no added lubrication. Generally, if there are grease fittings evident the motor needs periodic lubrication. None if not.

Check the lubrication instructions supplied with the motor for the particular frame size indicated on the motor nameplate.

Warranty: Does not cover any damages to the equipment resulting from failure to observe the above precautions. Refer to Armstrong General Terms and Warranty sheet. Contact your local Armstrong representative for full information.

WARNING: Whenever any service work is to be performed on a pumping unit, disconnect the power source to the driver, lock it off and tag with the reason. Any possibility of the unit starting while being serviced must be eliminated. If mechanical seal environmental accessories are installed, ensure water is flowing through the sight flow indicator and that filter cartridges are replaced as recommended. (See Armstrong files 43.85 and 43.86 for seal environmental instructions).

WARNING: Hydronic system components may be pressurized which, if suddenly released, can cause serious injury or death. When performing any kind of service to the pump, the pressure must be released in the system and the unit should be properly drained before starting any service work.

CAUTION: Exercise extreme care when handling power wiring. Ensure that the fuses are removed or breaker disconnected in the power line to the motor.
