Safe Operation Rules
Cut off the power and relieve the pressure at the hydraulic end before repairing or moving the pump.
When connecting or disconnecting the metering pump, make sure that the valve between the system pipe and the
pump is closed.
When inspecting the liquid end, if harmful or unknown liquid is measured at the liquid end, please wear
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.
If the liquid is easy to crystallize and solidify, please promptly clean up the liquid pump end.
Before starting up the metering pump, ensure that the valve between the system pipe and the pump is open and the
whole pipe is in a smooth state.
Install an appropriate number of filters at the end of the inlet pipe of the metering pump to avoid the pipe blockage
or pump valve blockage.
To ensure the accuracy of measurement, calibration must be performed in any service environment.
