Selection of high-pressure oil pumps
Thread Content
Our company has 5 high-pressure reaction kettles, which require hydraulic oil pumps to circulate the oil under a pressure of 25 kilograms, that is 2.5 MPa. Could anyone give some suggestions regarding the model, manufacturer, price, and specifications? Thank you all
The pressure is relatively high, making internal gear pumps unsuitable. A standard external gear pump will suffice.
The parameters and requirements are incomplete, so it is impossible to resolve the original poster’s issue. Basic parameters: flow rate, inlet and outlet pressures, name of the medium, density of the medium, viscosity of the medium, operating temperature, etc. What type of pump do you want to use? Screw pump? Gear pump? Centrifugal pump?
A gear pump is more suitable; Hebei Hengsheng
The screw pumps produced by Tianjin Industrial Pump Factory are more than capable of meeting the requirements, as the oil system supporting these units has a proven track record of excellent performance. 25KG is not a very high pressure either; the outlet pressure of the seal oil pump in ammonia synthesis compressors is 145KG, and such systems have been in use since the 1970s.
Apart from the viscosity of the oil, the poster did not provide another key parameter: flow rate. However, I think using plunger pumps and screw pumps is no problem; gear pumps are not very suitable.
