A small oil pump for transporting hot diesel?
Thread Content
Based on the following conditions, what pump is suitable? I heard that oil pumps are prone to leakage when exposed to high temperatures. Medium: diesel; Temperature: 180 degrees (some posts state that heat oil pumps should be used at temperatures above 200 degrees). Pressure: It is connected to a small pressure reduction tower (2.5 meters tall), so good sealing performance is required. Since it is a small experimental setup, the flow rate is not high, around 2 m3/h (33.3 L/min) :)
Inlet and outlet pressure? Given its small size, for a testing setup it is advisable to choose any plunger pump; such pumps are sufficient for low flow rates, do not require consideration of cavitation, and are generally inexpensive with easy installation and maintenance
The inlet pressure is around 5 KPa, while the outlet pressure is 0.1 MPa. Since the fluid needs to be returned to a vacuum tank, piston pumps are likely to be more expensive, right? Will a centrifugal pump work fine at 180 degrees in temperature? Will it leak? :) This post was last edited by calb on 2009-2-26 21:05 ]
