Pump has insufficient flow rate for the combination with Hexler 37072-0092 recommended by JABSCO!!
I ordered this pump in combination with the JABSCO motor and pump unit 37072-0092 (item no. 24981) and installed it. Hoses and all check valves have been replaced and are new. The pump delivers the nominal output (11lm measured with a bucket and stop watch) BUT that is not enough for the flow rate of the rinse pump!! In WET mode (rinse & vacuum together) the hose runs dry and after the flushing process smelly tank air comes back through the hose into the toilet and rises with large bubbling bubbles. Smells very unpleasant, almost unbearable!
On the other side of the hull, however, the same rinse pump unit is installed, also brand new, with the old JABSCO rinse pump (PAR-MAX4 Rinse Pump Model No. 31631-1092) with a flow rate of 14.4lm instead of 11lm. Here the hose always remains filled with water and even after the flushing process stops no air comes back out of the tank.
...therefore we strongly recommend NOT buying this pump in combination with Hexer 37072-0092, as in my opinion it does not have sufficient flow capacity! (even if this is recommended by Jabsco)
