摘要
A system allows pumps to run in parallel and preventing back flow through a non-operational pump. The system includes a first pump in parallel with a second pump. The system further includes a check valve in fluid communication with the first pump for preventing flow through the first pump when the first pump is not operating. The system further includes a sensing valve in fluid communication with the first pump and the second pump. The system also includes a load sharing valve in fluid communication with the check valve, the sensing valve, and the second pump for controlling a system flow, wherein the system flow is provided by the first pump when the second pump is not operating, and wherein the system flow is provided by the second pump when the first pump is not operating, and wherein the system flow includes a portion of flow from both the first and second pumps when both pumps are operational.
