CHECKS TO PUMP DELIVERY, STORAGE All M PUMPS PROCESS pumps are tested before shipment and carefully packed for transport: at the reception of the pump make sure that the pump has not been damaged during the transport. If there are problems, contact immediately the carrier and inform M PUMPS PROCESS about what happened. -
Page 15: Assembly, Installation, Connections, Commissioning And Setting
Ensure that the heated air from other units does not affect the pump; the air temperature must not exceed 40 °C, for higher temperatures contact your distributor M PUMPS PROCESS; ensure also the free circulation of air cooling of at least ¼ the engine diameter, because either the pump or the motor should be able to dissipate the heat by natural air convection. -
Page 16: Lubrication
Lubrication 14.4. Three options are available for bearings lubrication, - grease, - oil mist - oil cascade inside bearing housing. Ball-Bearings Lubrication by Grease Before placing the pump in operation, it must have grease supplied to the thrust bearings, the line bearing is life greased. - Page 17 Oil Lubricated Ball-Bearings Preparation of bearing housing Bearing frame must be carefully cleaned before filling with oil. It is also good practice to flush it with oil, compatible with the lubricating oil that will be used. The reservoir is to be filled to appropriate level as illustrated in the picture below. The oil level must be maintained at the correct level: decreasing of oil level may cause overheating and failure of the bearings, while exceeding the correct level can result in leakage.
- Page 18 Trico oiler setting (standard) a) Initial fill via top of housing, using overflow plug to establish correct level (refer to the picture above b) Release thumb screw and remove bottle. Establish a measurement from the center line of the oiler connection in bearing housing to the upper cross arm of amounts indicated in the following table this can be obtained by completely screwing down constant level oiler lower arm.
