1. The two key considerations when choosing a pump for oil transfer
When you choose a pump to transfer oil, you should pay attention to two things:
On the one hand, change the pump's materials to fit the oil. On the other hand, reduce the pump's rated power.
The first point is easy to understand. You should choose the proper materials to work stable with oil.
But what does the second point mean? Let me explain further below.
2. Why reduce the pump's max rated power?
You should reduce the pump's max rated power by asking the manufacturer to change the coil winding. And meanwhile, you should lower your expectations of the pump's performance.
When using a water pump to transfer oil, its load becomes larger due to the oil's viscosity. As a result, its head and flow become lower.
And at the same time, the pump's working current will increase because it is positively related to the pump's load.
The increased current will cause more heat and the pump's risk of burning out increases.
From all the above, you should reduce the pump's rated power to avoid the possible burnout caused by the increased current.
