Page 9: How It Works-Internal Gear Technology
S E C T I O N 3 How It Works—Internal Gear Technology The G SERIES GEAR PUMP is a rotating, positive displacement pump. These drawings show the flow pattern through the pump upon its initial rotation. It is assumed that the pump has no fluid in it prior to its initial rotation. The shaded area indicates the liquid as it is As the rotor continues to turn, the liquid is drawn into the liquid inlet port of the pump. -
Page 10: Suggested Installation & Operation
S E C T I O N 4 Suggested Installation and Operation G Series gear pumps are designed to meet the performance requirements of even the most demanding pumping applications. They have been designed and manufactured to the highest standards and are available in a number of different sizes to meet your pumping needs. - Page 11 BASE INSTALLATION AND GROUTING NOTE: Before the baseplate is installed, it is advisable to thoroughly clean the underside to enable the grouting to adhere to it. Do not use oil-based cleaners since grout will not bond to it. Once the concrete pad has cured, the baseplate can be carefully lowered over the anchor bolts. Place shims or tapered wedges under the baseplate at each of the anchor bolt positions to provide about 0.75"...
- Page 12 ALIGNMENT OF PUMP/DRIVER SHAFTS WARNING! NOTE: Driver power must be locked out before beginning any alignment procedure. Failure to lock out driver power may result in serious physical injury. NOTE: Proper alignment is the responsibility of the installer and user of the equipment. NOTE: Check alignment if process temperature changes, piping changes and/or pump service is performed.
- Page 13 Since the G-Series pump is foot-mounted, its shaft centerline will rise when handling pumpage at elevated temperatures. Similarly, the motor shaft centerline will rise as it reaches its operating temperature. Therefore, we will often purposely misalign shafts vertically during cold alignment to allow for thermal growth, thus bringing the shafts into alignment at operating temperature. This is shown in the “COLD SETTING OF PARALLEL VERTICAL ALIGNMENT”...

Page 15: Maintenance
S E C T I O N 5 Maintenance GENERAL MAINTENANCE WARNING: For G Series pumps equipped with jacketed casing, ensure pump is fully cooled prior to conducting inspection, repair, or maintenance. CLEANING: G Series pumps must be maintained and kept as clean as possible. This will allow for quick inspection, adjustment and repair work. - Page 16 INSTALLATION NOTE: Never touch mechanical seal faces with anything except clean hands or a clean cloth. Small particles can scratch and damage the seal faces, resulting in seal leakage. Clean the rotor shaft and the seal housing bore. Make sure they are free of dirt, burrs and scratches. Using emery paper, gently smooth the leading edge of the shaft’s diameter.

Page 17: Disassembly
S E C T I O N 6 Disassembly BEARING HOUSING REMOVAL Insert a length of brass through the port opening and in-between the rotor teeth in order to lock the pump and secure the shaft from turning. Bend the lock washer tang upwards. Using a spanner wrench, remove lock nut and lock washer from shaft. - Page 18 PRESSURE RELIEF VALVE DISASSEMBLY Place a mark on the valve and head prior to disassembly in order to ensure proper reassembly. Remove the pressure relief valve cap. Measure and record the extension length of the adjusting screw. Loosen the pressure relief valve lock nut and then back out pressure relief valve bonnet and adjusting screw until the spring pressure is released.

Page 19: Reassembly
S E C T I O N 7 Reassembly BEARING HOUSING ASSEMBLY Clean all parts thoroughly. Install the bearing housing lip seal. Refer to Figure G and Figure H for proper orientation. Insert the bearings into the housing. It is best practice to pack the bearings with NLGI #2 multi-purpose grease (or equivalent) before installation. - Page 20 Install the idler bushing. Carbon graphite bushings require additional precautions during installation to prevent cracking**: Use a press for installation. Lightly lubricate the bushing and the bore. Ensure bushing is aligned straight before starting. Do not stop the pressing operation until bushing is in the proper position; starting and stopping will result in a cracked bushing.
- Page 21 Stake one (1) tang of lock washer into the slot of lock nut after torquing. Failure to properly torque the lock nut or engage the lock washer tang could result in premature bearing failure and damage to the pump. Finally, remove the length of the brass from the gear teeth.
