28 Study instruction manuals and observe the warnings before installation, operation, service and maintenance. Not following the instructions can result in serious accidents with fatal injuries. In order to make the information clear only foreseeable conditions have been considered. No warnings are given, therefore, for situations arising from unintended usage of the machine and its tools. P000272A A summary of the safety information is found in the Safety chapter under divider 1.

32 1 Function Description 1.1 Application The feed pump is used to feed lube oil, gas oil, or marine diesel oil to the separator. 1.2 Design The pump is of constant flow vane type. The pump unit consists of an electric motor and a pump. 1.3 Working Principle The working part of the pump is a rotor with seven vanes which rotate inside an eccentrical stator. Individual cavities are formed between the vanes and the stator. When the cavities are filled with oil, the oil is transported to the separator inlet. Priming The pump will not work properly if the cavities are not completely filled. If the pump is not completely filled, disconnect the flexible hose on the separator inlet and fill with oil. Direction of Rotation The direction of rotation is shown by an arrow on the electric motor

33 1 Function Description Feed Pump

34 2 Fault Finding Fault Probable cause Remedy Low capacity or low pressure Suction valves shut off, or clogged strainer Open the valves, or clean the strainer Pump does not prime Pump too dry Air leak on suction side of the pump Fill the pump housing with oil Seal off the air leak Drive motor tends to stop by tripping the overload relay The counter pressure after the pump is too high The cut-off setting of the motor relay is too low Check the valves between pump and separator Adjust the relay setting according to the motor power rating in Amps Pump noisy when running Suction valves shut off, or clogged strainer Air leak on suction side of the pump Heavy wear in the pump Open the valves, or clean the strainer Seal off the air leak Dismantle the pump and replace the worn parts

36 3 Maintenance WARNING Entrapment hazard Do not start maintenance work unless the power is switched off and the inlet and outlet are shut. 3.1 Dismantling and Assembly Dismantling the pump P002061A 1 Hexagon screw 6 Vane 2 Front flange/distributor 7 End flange 3 O-ring 8 Shaft seal ring 4 Stator 9 Hexagon screw 5 Rotor 1. Disconnect the suction and pressure pipes from the front flange/distributor (2)

37 3 Maintenance Feed Pump 2. Loosen and remove the four hexagon screws (1), securing the pump to the electrical motor. 3. Remove the pump from the electrical motor shaft. 4. Loosen and remove the three hexagon screws (9) on the end flange (7) that secure the front flange/distributor (2) to the end flange. 5. Be careful when taking out the rotor, the vanes are not fixed. Remove the stator (4) and the rotor (5) with vanes (6). 6. Remove the shaft seal ring (8) on the end flange (7) and clean the recess. 7. Remove the O-ring (3) on the front flange/ distributor and clean the groove. Assembling the pump P002061A 1 Hexagon screw 6 Vane 2 Front flange/distributor 7 End flange 3 O-ring 8 Shaft seal ring 4 Stator 9 Hexagon screw 5 Rotor 1. Apply oil to the new shaft sealing lip and the outer rim of the shaft sealing. 2. Press in the new shaft sealing, flush with the end flange (7)

38 Feed Pump 3 Maintenance 3. Fit the new O-ring (3) on the front flange/ distributor (2). 4. Fit the stator (4) onto the gauge peg on the front flange/distributor (2). 5. Place the rotor (5) with vanes (6) inside the stator (4). 6. Fit the end flange (7) and secure the front flange/distributor (2) to the end flange with the three hexagon screws (9). 7. Mount the pump on the electric motor shaft. 8. Tighten the four hexagon screws (2), securing the pump to the electric motor. 9. Connect the suction and pressure pipes to the front flange/distributor (2)
