Conclusion

MR74 Bearing： When using MR74 bearing for pump starting power, the motor starts relatively slow, which will have some effect on the back and forth oscillation pulse of the diaphragm and is affected by the environment. As the temperature drops, the starting current will rise.

Sleeve Bearing：The performance of the pump with sleeve bearing is more stable and less influenced by the environment. The starting current hardly bi due to temperature drop.
