Page 5: Section 1: System Description
Section 1: System Description The Geoflo 3 is a three inch diameter deep well submersible pump mainly designed for the pumping of raw water in domestic water supply. This manual is designed to assist in the proper set-up, installation, and operation of these pumps. -
Page 6: Section 2: System Installation
CAUTION: This pump has been approved for pumping water of a maximum 86°F only. Liquid Temperatures/Cooling Figure 2-1 shows a Geoflo 3 pump installed in a well. With the pump operating, it illustrates the following: Well diameter ... - Page 7 Figure 2-1: Pump Inside Well Motor Preparation Geoflo 3 submersible motors have water-lubricated slide bearings. No additional lubrication is required. The submersible motors are factory-filled with a special motor liquid, type SML 2 or SML 3, which will protect the motor liquid down to 4°F and prevent...

the growth of bacteria. The level of motor liquid is important for the operating life of the bearings and consequently the life of the motor. Refilling of Motor Liquid If for any reason the motor liquid has been drained or lost, the motor must be refilled with Geoflo motor liquid SML 2 or SML 3. -
Page 9: Installing The Pump
Installing the Pump Installation Depth The dynamic water level should always be above the pump, see Figure 2-4. A = Dynamic water level B = Static water level C = Minimum 3 inch well diameter D = Drawdown E = Installation depth below static water level. - Page 10 Installation Depths Maximum installation depth: 500 feet below the static water level. Minimum installation depth: 1.75 feet below the dynamic water level. Vertical Installation During start-up and operation, the pump must always be completely submerged in water. Horizontal Installation The pump must be installed at least 1.75 feet below the dynamic water level. If there is a risk that the pump might be covered by mud, the pump must always be placed in a flow sleeve.

The current consumption can only be measured accurately by means of a true RMS instrument. If other instruments are used, the value measured will differ from the actual value. The Geoflo 3 pumps can be connected to a CU 300 control box. Motor Protection The motor has built-in automatic thermal overload protection and requires no additional motor protection. - Page 12 WARNING: Reduced risk of electric shock during operation of this pump requires the provision of acceptable grounding. If the means of connection to the supply connected box is other than grounded metal conduit, ground the pump back to the service by connecting a copper conductor, at least the size of the circuit conductors supplying the pump.

Page 13: Cable Sizing
Note: The values apply to 230 V, 60 Hz, and conform to the requirements stated in the National Electrical Code Book. Note: Recommended maximum cable length between the Geoflo 3 and the CU 300 control box = 650 ft. Splicing the Cable The submersible drop cable can be ordered separately in lengths of 25 to 300 ft., see... -

Figure 3-5: Gripping the Pump Generator Operation It is safe to operate the Geoflo 3 with a generator. The generator must be sized 50% above the P1 (input power) values of the pump. See the following table. Motor... - Page 15 Switch off the electricity supply for 1 minute. Geoflo 3 Motors NOTE: All Geoflo 3 motors are factory-set to detect dry-running conditions. However, if the maximum pump speed setting is changed, the dry-running stop value must also be changed. Please refer to CU 300...

Page 16: Assembly Of Pump And Motor
Assembly of Pump and Motor To assemble pump end and motor, proceed as follows: Place the motor horizontally in a vice and tighten it, see fig. 3-7. Pull the pump shaft out to the position shown in fig. 3-6. Grease the motor shaft end with the grease supplied with the motor. Screw the pump end on the motor (55 Nm). -
Page 17: Section 4: System Maintenance
Section 4: System Maintenance The pumps are normally maintenance-free. Deposits and wear may occur. For that purpose, service kits and service tools are available from Geotech. The pumps can be serviced at a Geotech service center. -
