I believe it is a constant displacement pump, not peristaltic.
Peristaltic pumps do not have

Further support for a lower net flow rate during the October 6 testing
is given by the measurement performed by Mats near the end of the
run. He very carefully measured a rate of .9 grams per second being
careful not to disturb the plumbing. This value coupled with the

It may be possible to replace the peristaltic tube and thus get a result
which exceeds the maximum for a standard tube.
I have been trying to understand the unusual behavior of the ECAT water input
pump. It appears that the same pump was used in both of the recent
demonstrations. Mats Lewan made excellent notes during his September test that
accurately measured the pump output at several points in time. The
