How to Maintain and Clean a Manual Rotary Oil Pump?

Daily maintenance and cleaning are crucial to keep the manual rotary oil pump in optimal working condition.After each use,clean the residual oil and liquid inside the pump body,suction tube and discharge hose to prevent liquid residue from solidifying,blocking the pipeline or corroding internal components.Regularly inspect the sealing rings,gaskets and rotating parts,check for aging,deformation and wear,and replace vulnerable parts in time to avoid liquid leakage.For long-term unused pumps,conduct regular trial rotation to prevent internal mechanical rust and jamming.Keep the equipment dry and clean during storage,avoid humid,high-temperature and corrosive environments.Do not place heavy objects on the pump body to prevent structural deformation.When switching different transfer liquids,thoroughly clean the pump interior to avoid liquid mixing and contamination.
