Dunno. Try ringing the manufacturer, who alone can tell from their records whether the current shaft-end seal fitted to that serial-numbered pump is suitable for pressure reversal, if indeed it doesn't already say one way or the other in the user manual they supplied with it.

No they are not, you will ruin the shaft seals and bearings.

Do you mean Archimedean screw, eccentric screw or something else?
