7. is advisable to support heavy suction lines so that their weight doesn t pull on the pump 5 5 Suction Head The total gauged suction head which is the height between water level and pump plus loss of friction in pipe and possible filter resistance is not to exceed 7 5 m not forgetting that in dry seasons the water level in the well may be lower than usual If suction lines are very short or the suction head under 2 m or where booster is present a regulator valve not a tilted valve seat must be installed in the suction line directly in front of the pump This regulator valve can be adjusted with greater accuracy to the required suction head ensuring the avoidance of water hammer 5 6 Intake Pressure Pump Unit as Booster Set If the inlet pressure is more than 0 3 bar 3 m it is advisable to install a pressure free tank with float valve If this can t be done a regulator valve as described above must be installed A vacuum of 4 6 m must be provided if the automatic air volume control is to function properly If the pump hammers a suction air chamber approx 7 5 litre must be installed in the suction line Moreover a shut off valve is necessary in a suction line with intake pressure so that the pump can be opened for servicing 5 7 Discharge Line Refers only to installation of pump units with vertical tanks or pumps alone Important If possible the line should slope upwards from the pump to the tank or at least be horizontal
8. it could be that too much air is being pumped In this case it is advisable to disconnect the pipe of the air volume control for a while or install a special rubber lip with a very small hole into the snifting valve b Suction line leaks Find leak and seal it 8 6 Water is pumped easily till shortly before switch off pressure is reached where after the pump continues to run but doesn t pump any water because it can t reach the final pressure Possible Reason Remedy This can happen if too much air is pumped through the air volume control when suction lines are very long and suction head very high This often occurs when the suction line isn t absolutely seal proof and allows even more air to get into the pump It can also be caused by worn rubber valve plates worn cylinder or pistons We recommend either installing a rubber lip with a very small hole or to disconnect the tube of the air volume control from time to time Replace rubber valve plates 113 123 Check whether piston or brass cylinder are worn and replace as necessary 8 7 Water leaks at Air Volume Control Possible Reason Remedy Rubber lip of snifting valve 29 is damaged Replace rubber lip 29a lt Suction Line A Discharge Line Fig 111 Pumpmeister Pump Unit 12
