Abstract: The invention relates to a mobile pump system for pumping water and/or extinguishing agent and an associated method therefor. The mobile pump system comprises: a frame for housing the pump system; a booster pump arranged in the frame; one or more submersible pumps arranged in the frame; a booster pump motor drive configured to drive the booster pump; a hydraulics motor drive configured to drive the one or more submersible pumps and wherein the hydraulics motor drive is configured to function as auxiliary drive for the booster pump; and a coupling for coupling the booster pump to the hydraulics motor drive such that the hydraulics motor drive can function as auxiliary drive for the booster pump.

Abstract: An extinguishing system and method for extinguishing fires. The extinguishing system includes—a pump system for pumping extinguishing agent; one or more nozzles connected operatively to the pump system for the purpose of spraying extinguishing agent at a source of fire; a supply or inlet arranged on the pump system for the purpose of supplying extinguishing agent to the pump system; an extinguishing conduit with an extinguishing length arranged on the pump system for the purpose of supplying extinguishing agent to the at least one nozzle; and an extinguishing controller provided with an input system for inputting system data, including data about the extinguishing conduit, the pump system and the at least one nozzle. The extinguishing controller is configured to determine with the system data an operating pressure at or close to the at least one nozzle and thereby control the pump system.

Abstract: A retracting device and method for retracting a hose, the device comprising: a frame; at least one drive roller connected to the frame for driving the hose for retraction; a first and a second pressing element operatively connected to the at least one drive roller and suitable for pulling the hose upward in co-action with the at least one drive roller; an activating element operatively connected to the two pressing elements and suitable for activating the pressing elements such that no more than one pressing element presses against the drive roller.
