Abstract
A mobile pump system for pumping water for extinguishing with an auxiliary agent, and a method therefor. The mobile pump system includes a frame for housing the pump system, a booster pump arranged in the frame, a metering pump arranged in the frame for the purpose of adding an auxiliary agent to a water flow, and a drive configured to drive the booster pump and the metering pump. The metering pump is provided with a displaceable metering pump frame and coupling means for connecting the metering pump to a container of the auxiliary agent.
Claims16
A mobile pump system for pumping water and/or an extinguishing agent, the mobile pump system comprising:
- a frame for housing the mobile pump system;
- a container-type housing enclosing the frame, the container-type housing comprising a plurality of walls, the plurality of walls comprising sound insulation for reducing noise emissions from within the housing;
- a booster pump arranged in the frame for the purpose of pumping a water flow;
- a metering pump arranged in the frame for the purpose of adding an auxiliary agent to the water flow, the metering pump comprising a displaceable metering pump frame and coupling means for connecting the metering pump to a container of the auxiliary agent;
- a drive configured to drive the booster pump and the metering pump;
- and
- a controller configured to control the booster pump and the metering pump;
- wherein the controller is configured to continuously monitor and control the booster pump and the metering pump to achieve a desired mixing ratio of the auxiliary agent in the water flow;
- wherein the coupling means comprise a first connection for a first container and a second connection for a second container;
- wherein the first and second connections are provided with separate shut-off valves;
- wherein the first container is a container of the auxiliary agent;
- and
- wherein the second container is a container of the auxiliary agent.
