Page 8: Installation
INSTALLATION INSTALLATION 1. Mounting surface should be flat and level. 2. The suction line should be kept as short as possible and present minimum friction loss. 3. Suction and discharge lines must be fully supported and installed so that no expansion or shock forces act on the pump which could lead to distortion. -
Page 9: Troubleshooting
TROUBLESHOOTING Problem Cause Solution Pump not turning Interruption of electrical power Reset circuit breaker, check fuses. Key sheared or missing. Replace. Coupler or belts are not connected. Replace or adjust. Pump shaft or gears sheared. Replace. Wrong rotation. Reverse. Relief valve not properly adjusted. Adjust valve. -

PUMP HOUSING ASSEMBLY Before install the pump housing to the gearbox make sure that cleaning on the surface of pump hosing and gear box and check to the shim plate between pump housing and gear box. -
Page 13: Rotor Clearance
ROTOR CLEALANCE Rotor clearance must be precisely maintained to provide maximum pumping efficiency, yet prevent contact between rotors, rotor housing, and front cover during operation. If pumping efficiency is below expectations, or if parts contact has occurred during operation (Within rated differential pressure), check, rotor clearances and adjust if incorrect. -
Page 14: Rotor Timing
ROTOR TIMING Rotor timing must be precisely maintained to provide maximum pumping efficiency, yet prevent contact between rotors during operation. If pumping efficiency is below expectations, or if rotors contact during operation (within rated differential pressure), check rotor timing and adjust if incorrect. Also check rotor timing after any gearbox dismantling when the gears are removed and/or replaced. -

SHAFT AND BEARING REPLACEMENT Gearbox Disassembly 1. Remove the oil drain plug and drain the oil. 2. Remove the gear box cover bolts (6) from the rear cover (4). 3. Pull the rear cover off the drive shaft extension. If the cover stuck use a soft hammer carefully to loosen it. - Page 16 Gearbox Assembly 1. Clean and lubricate the front and rear bearing areas of the drive and idle shafts with oil. 2. Fit the front bearing, spacer and rear bearing on the shaft by arbor press or heat 120C (250F) up by heater. 3.
