Page 3 Notes: If you encounter any problems when using the Ailipu metering pump, please first refer to the operation and maintenance manual for trouble removal. If the problem can’t be resolved, please contact your local Ailipu sales representative or our Technical Services Department.
Page 4 appropriate protective equipment for operation, empty and clean the liquid end at the same time. All pumps are inspected with water before delivery. If the liquid transported reacts with water, make the pipes of the pump fully dry before use. When equipment doesn’t transfer liquid for a long time, please shut down the pump and cut off the power supply.

0.1 ㎜. Regular plunger metering pump are used in the temperature of -30~200℃ and a viscosity of 0.3~800mm2/s. (if exceed this range, please advice AILIPU company). Plunger metering pump has the characteristics of simple structure, convenient maintenance, and high cost-effectiveness, which can transport high viscosity medium.
Page 6: Product Code
1.1 Product Code II、 Pump Structure and Working Principle The metering pump generally consists of a pump motor, a driving end, and a hydraulic end (see Figure 1). Fig.1 Metering Pump Outside Drawing...
Page 7: Working Principle Of Driving End
Working Principle of Driving End The transmission box is composed of an arch cam mechanism, a stroke adjustment mechanism and a worm gear reduction mechanism. Working Principle A high-speed rotating motor shaft, which transmits torque through an elastic worm coupling (20), slows down by a worm (22) and a worm gear (8), and rotates the cam (6) on the worm gear bearing through the rotation motion of the worm wheel.

Page 9: Hydraulic End
2.2 Hydraulic End The structures of hydraulic ends for the plunger metering pump shown in Figure 3 ) mainly consists of the plunger, the pump head, the inlet and outlet valves and the seal packing. Working Principal： The plunger is mechanically connected with the cross head (arch prop head) and simultaneously makes the straight reciprocating motion together with the cross head.
Page 10: Flow Adjustment
2.3 Flow Adjustment Rotate the adjusting handwheel (30) and with the help of the stroke adjusting rod (34) and the adjusting rod sleeve (37) to change the distance between the front and rear prop blockers (2) and the center of the cam, thereby changing the stroke length of the cross head (plunger).

3.6 Safety valve and buffer tank of the pipe are important accessories of the metering pump. The pipe safety valve is usually installed in the discharge pipe behind the centralized liquid pipe, which has the function to prevent the pressure of the outlet pipe being too high, so as to protect the safe operation of the pump. The buffer tank is used to reduce the non-uniformity of the flow in the pipe and then to reduce the flow fluctuation.
Page 12: Operation
4.3. Operation Upon completion of the above preparatory work and confirmation, start the motor and put it into operation. The operation process should be stable, and there should be no abnormal noise, otherwise please shut down the pump to check. After finding the source of noise, please put it into operation again. 4.4 Flow Calibration Pump flow calibration test should be carried out in the initial pump operation, so as to confirm the exact flow under specific operating conditions.
Page 13: Disassembly And Reassembly
Before maintenance, stop the metering pump, release the system pressure, and close pump inlet and outlet valves connected to the system. During maintenance, avoid any action leading to an accident, post a notice of under maintenance on the power switch, and immediately disconnect power during operation in case of any fault 5.2 Disassembly and reassembly 5.2.1Disassembly of components for hydraulic end...
Page 14 Disassemble the coupling screws between the pump head bracket and the transmission box body, pull out the bracket horizontally. Pull out the arch prop 2 from the front of the box body, then complete the disassembly. 5.2.3Reassembly of the transmission box Clean and inspect all parts before assembly, and replace new parts for worn-out parts that cannot be repaired.
Page 15 5.2.4 Reassembly of the hydraulic end components Clean and inspect all parts before assembly, and replace new parts for worn-out parts that cannot be repaired. Reassemble the hydraulic end components in the reverse sequence according to the disassembly sequence. Please pay attention to the following things: Sealing inspection of the inlet and outlet valves Flow accuracy of the metering pump depends largely on the sealing contact accuracy between the valve balls and...
