• Description:
  The Bureau of Mines conducted a series of tests to determine how well the Bendix BDX 60, the Gilian HFS 113u, the MSA Fixt-Flo, and the Spectrex PAS-3000 dust sampling pumps control the flow rate at 2 l/min. These tests were performed because users need to know the performance characteristics of sampling pumps to select the pump that best satisfies their sampling requirements. Long-term (6- to 8- h) flow stability at various backpressures was examined in relation to the flow control tolerance of +-5% of the flow, the level imposed by federal regulations; four of the five Bendix pumps did not meet the criterion for this test, which was passed by all other pumps tested. Flow control recovery times were measured at transient backpressures; all pumps evaluated met the criterion for this test. The low-flow indicators of the sampling pumps were tested; only two Bendix pumps and one Gilian pump met the criterion of indicating a flow change greater than +-5%. In the pulsation flow measurement test all of the pumps passed, with pulsating flows greater than 20 hz. The Bureau also evaluated the manuals accompanying the sampling pumps. All were judged adequate except the Spectrex manual, which was judged poor. [Description provided by NIOSH]
