How to handle off-center flow in a pump setup with two operating pumps and one standby pump
Thread Content
Ladies and gentlemen: How should we handle the issue of flow deviation in the operating pump when there are two pumps in operation with one as a backup? Please talk about it.
The degree of flow deviation is determined by measuring temperature and outlet pressure, and adjustments are made by controlling the oil outlet valve or control valve； If variable-frequency control is available, it can be adjusted using variable frequency
During the design phase, the inlet and outlet pipes should be arranged as symmetrically as possible for the three pumps. If it has already been installed, adjustment can only be done through the outlet valve.

Adjust the opening degree of the inlet valve according to the outlet pressure to maintain a consistent outlet pressure.
