Pump heads in twin-head pumps
The twin-head pump housing has a flap valve on the
outlet side. The flap valve seals off the port of the idle
pump housing to prevent the pumped liquid from
running back to the inlet side. See fig. 2. Due to the
flap valve, there is a difference in the hydraulics
between the two heads. See fig. 3.
