The graphic shows a comparison of the
suction volumes of both pump versions.
In the single-stage ABS return pump, the
entire suction volume must be drawn in and
flow through the suction line during one
piston stroke (piston stroke from TDC to BDC). The suction pressure is correspondingly high
and increases with increasing viscosity.
Cavitation and the associated drop in
performance on the pressure side, are the
results.
