Concentric Pumps Limited, a subsidiary of Concentric plc, has completed the installation of pressure pulsation testing facilities in the first of its manufacturing cells. The new equipment enables Concentric to screen all pumps emerging from the cell in preparation for cold engine testing at the end of the customer’s line, when they have been assembled into the complete engine. This facility is becoming increasingly desirable, as more engine manufacturers adopt cold testing. The test rig incorporates a silicone diaphragm pressure transducer which measures pulsing levels within each pump. The results are stored in an electronic database, providing full traceability of the performance of all finished product, together with the ability to correlate and analyse data across a large number of pumps.
