A liquid ring pump manifold, comprising:
- an integrated non-return valve, the integrated non-return valve being configured to permit flow of fluid through the liquid ring pump manifold in a first direction and to prevent or oppose flow of fluid through the liquid ring pump manifold in a second direction, the second direction being opposite to the first direction.
A liquid ring pump comprising:
- a housing defining a chamber therein;
- a shaft extending into the chamber;
- an impeller fixedly mounted to the shaft;
- and
- a liquid ring pump manifold comprising an integrated non-return valve, the integrated non-return valve being configured to permit flow of fluid through the liquid ring pump manifold in a first direction and to prevent or oppose flow of fluid through the liquid ring pump manifold in a second direction, the second direction being opposite to the first direction, the liquid ring pump manifold being fluidly connected to the chamber.
