A system for the transfer of reactive resins components from a remote source to the point of application

摘要

The dispensing assembly for transferring at least two liquid components from a remote source to a metering device and for replenishing component accumulators independently of whether the unit is metering or not, comprises a metering device (1A) for at least two components (31A, 31B) with a metering pump (2, 3) and a remote bulk container (32A, 32B) for each component, whereby for each component the bulk container is connected via a low pressure transfer pump (33A, 33B) and low pressure transfer hose (6A, 6B) to a pump inlet adaptor (5A, 5B) of the metering pump (2, 3) as well as to an accumulator assembly (9, 10) situated immediately before the inlet of the metering pump. This allows the use of low pressure transfer and low pressure metering systems instead of high pressure metering and high pressure transfer systems and hence lower cost dispensing assemblies.
