Poor-quality pump

Is it necessary to install a forced lubrication system for the lean methanol pump?
There is no need to install a forced lubrication system for the lean methanol pump. Our company uses methanol-poor pumps from United Pumping Company in the United States; all that is required is to fill the oil filler bottle with oil of the correct grade, maintain an appropriate liquid level, keep the housing clean, and regularly check the viscosity of the oil.
Forced lubrication mainly depends on the pressure requirement of the pump for the lubricating oil. For forced lubrication, it is also related to the size of the pump; if the pump is larger, the weight of the rotor increases, and a higher oil pressure is required to support the rotor.
“Forced lubrication is also related to the size of the pump; if the pump is larger, the weight of the rotor increases, and a higher oil pressure is required to support the rotor. ”What was said upstairs is correct: the lean methanol pump of the Xin Ao Da Qi model has a flow rate of nearly 500 m3/h and a head of over 900 meters, and it is equipped with a rare-type station; whereas the lean methanol pump of the Xin Ao Feng Huang model has a flow rate of only about 300 m3/h, with a head of also over 900 meters, but it does not have such a station. Both pumps use technology from United Pumps Corporation in the United States.
I consulted relevant manufacturers; one of them said it was not necessary to set it up, while another required it. Personally, I think adding a forced lubrication system means adding more points of failure, which will increase maintenance costs.
