Lances are arranged in groups, each with its own fluid supply. An Independent claim is included for the corresponding method of grouped distribution of pumps and pumping power. Preferred features: There is a common pump (26) and drive, for each group in the tank (1). A suitable pump and drive is provided for each single-lance group. Each lance (10) used in the arrangement, has a pump delivering fluid through its interior, a pump connection and a pump drive. Pump and drive are directly connected to the lance. Direct connection obviates individual couplings. Nozzles and/or screws(s) on the lance, generate flow. |
