MaintenanceMaintenanceMaintenance scheduleMaintenance inspectionsRoutine maintenanceA maintenance schedule includes these types of inspections:• Routine maintenance• Routine inspections• Three-month inspections• Annual inspectionsShorten the inspection intervals appropriately if the pumped fluid is abrasive or corrosive or if theenvironment is classified as potentially explosive.Perform these tasks whenever you perform routine maintenance:• Lubricate the bearings.• Inspect the seal.Routine inspectionsPerform these tasks whenever you check the pump during routine inspections:• Check the level and condition of the oil through the sight glass on the bearing frame.• Check for unusual noise, vibration, and bearing temperatures.• Check the pump and piping for leaks.• Analyze the vibration.• Inspect the discharge pressure.• Inspect the temperature.• Check the seal chamber and stuffing box for leaks.• Ensure that there are no leaks from the mechanical seal.• Adjust or replace the packing in the stuffing box if you notice excessive leaking.Three-month inspectionsPerform these tasks every three months:• Check that the foundation and the hold-down bolts are tight.• Check the packing if the pump has been left idle, and replace as required.• Change the oil every three months (2000 operating hours) at minimum.• Change the oil more often if there are adverse atmospheric or other conditions that mightcontaminate or break down the oil.• Check the shaft alignment, and realign as required.Annual inspectionsPerform these inspections one time each year:• Check the pump capacity.• Check the pump pressure.• Check the pump power.If the pump performance does not satisfy your process requirements, and the process requirements havenot changed, then perform these steps:1. Disassemble the pump.2. Inspect it.3. Replace worn parts.64 Model 3796 i-FRAME Installation, Operation, and Maintenance Manual
Maintenance (Continued)Bearing maintenanceThese bearing lubrication sections list different temperatures of the pumped fluid. If the pump is ATEXcertifiedand the temperature of the pumped fluid exceeds the permitted temperature values, then consultyour ITT representative.Bearing lubrication scheduleType of bearing First lubrication Lubrication intervalsOil-lubricated bearingsGrease-lubricated bearingsLubricating-oil requirementsAdd oil before you install and start After the first 200 hours, changethe pump. Change the oil after 200 the oil every 2000 operating hourshours for new bearings. or every three months.Grease-lubricated bearings areinitially lubricated at the factory.Regrease bearings every 2000operating hours or every threemonths.Oil requirements based on temperatureFor the majority of operating conditions, bearing temperatures run between 120°F (49°C) and 180°F(82°C), and you can use an oil of ISO viscosity grade 68 at 100°F (38°C). If temperatures exceed 180°F(82°C), refer to the table for temperature requirements.TemperatureOil requirementOil volumesOil volume requirementsBearing temperatures exceed 180°F (82°C)Pumped-fluid temperatures exceed 350°F (177°C)Use ISO viscosity grade 100 with bearing-framecooling or finned-tube oil cooler. The finned-tubeoil cooler is standard with the HT 3196 model andoptional for all other models.Use synthetic lubrication.This table shows the required amount of oil for oil-lubricated bearings.Frame Qts.
