Device (1) for facilitating the circulation of fluid coolant having, in compact form, a circulating pump (7), a settling cascade (17) and a negative-pressure pump (20) for suctioning a workpiece (54) onto a worktable (21). The transfer pump (7) and a negative-pressure pump (20) are connected to operate with one another in the coolant cycle and to prevent loss of coolant.

A fluid coolant circulation device for a workpiece processing means, comprising: a storage and collection tank, an injector pump for transferring and pressurizing the coolant, at least one fluid-jet negative-pressure pump, a settling cascade for cleansing the coolant, a heat exchanger, and pipes for transferring the coolant, including a first transfer pipe, one end of which is connected to an inlet of the injector pump and whose other end extends under the planned operational fluid level in the storage and collection tank, a second transfer pipe connecting an outlet of the injector pump with a coolant outlet of the device, a third transfer pipe connecting a coolant return flow inlet of said device to said settling cascade, a fourth transfer pipe connecting the outlet of the injector pump with an operational inlet of the fluid-jet negative-pressure pump, a fifth transfer pipe connecting a negative-pressure inlet of said device with a negative-pressure inlet of the fluid-jet negative-pressure pump, and a sixth transfer pipe extending from an outlet of the fluid-jet negative-pressure pump to under the planned operational fluid level in the storage and collection tank.
