摘要： The apparatus consists of a plurality of piston pumps having preset displacement ratios. A motor mechanism is connected to each of the pumps. In addition, there is a control mechanism connected to each pump ensuring that all pistons execute their previous stroke completely before being reversed and that they all start their following stroke at exactly the same moment. Furthermore there is another control mechanism controlling the speed of each piston so that all pistons complete their respective strokes simultaneously. A mechanism for adjusting and varying the pump displacement is also provided.

摘要： The invention relates to new single use volumetric pump meeting the stringent requirements for use in sterile environments like in the pharmaceutical and/or biomedical industry. A kit comprising a single action pump 1 with inlet 21 and outlet 31 connecting lines 2, 3 wherein the connecting lines are made with a flexible material allowing the line to be obturated upon pinching. A driving system adapted to operate the kit is also provided where pinching means are arranged to alternatively pinch the connecting line fastened to the inlet and the connecting line fastened to the outlet in synchronization with the piston translation.

摘要： A liquid feeding device includes a discharge channel, a pump part, a feeding pressure sensor, a non-discharge pressure sensor, a pre-compression part, and a pre-compression speed determination part. The pump part has a plurality of plunger pumps connected in series or in parallel to each other. At least one of a plurality of the plunger pumps of the pump part is a closed pump in which communication with the discharge channel is disconnected during a non-discharge time, in which a discharge process for discharging liquid to the discharge channel is not executed. The pre-compression part is configured to cause the closed pump that is after the suction process for sucking the liquid into a pump chamber is completed and during the non-discharge time to execute a pre-compression process to perform a discharge operation until a non-discharge pressure is substantially the same as a feeding pressure based on output of the feeding pressure sensor and output of the non-discharge pressure sensor. The pre-compression speed determination part is configured to determine a pre-compression speed of the closed pump in the pre-compression process.
