What happens if the pump’s medium is changed?
Thread Content
I have an acid water pump installed; it’s not in use now. Can it be converted into a gasoline pump to transport gasoline? Will the pump get empty? Please discuss topic 2, thank you, extra points
The type of pump isn’t specified either; how can we determine the suction height?
What is the model of the pump, its flow rate and head? What is the motor power? What are the diameters of the inlet and outlet pipes, and what are the flow rate and head required to transport gasoline?
The head will change; is safety guaranteed?
It depends on whether the parameters of the pump meet the requirements for transporting gasoline. Water does not vaporize, but gasoline does; once it vaporizes, the system becomes vacuumed. There are also issues related to the motor and other components. For reasons of safety, it is better to choose a new pump – do not use an inappropriate old pump just to save money, as such actions pose serious safety risks
For transporting gasoline, a sliding vane pump can be chosen; it has an extremely high self-priming capacity, is not affected by cavitation issues, and is safe and efficient
Please specify the detailed parameters. Please be thorough and careful. Please check my signature. Please provide further clarification
The design of a pump is based on specific parameters such as flow rate, head, specific gravity, viscosity, and other chemical properties of the fluid; materials are selected accordingly, and then the motor power is calculated. If these parameters change, the effects will be significant, unless the properties of the fluid remain similar.

The viscosity of gasoline should be similar to that of water; the viscosity of the fluid has a significant impact on the performance of centrifugal pumps, while density has almost no effect. The viscosity of gasoline should be similar to that of acidic water; as long as the inlet pressure is higher than the vaporization pressure of gasoline at the same temperature, there should be no major problems. I just made that up regarding the viscosity; I didn’t check it. What I mainly want to say is that viscosity affects the performance of centrifugal pumps, while density does not; density only affects power.
