Description
3.5

Gas ballast

When condensable vapours are pumped, they may be compressed above the saturated va-
pour pressure and condense.
Opening the gas ballast valve (1) in the
suction line of the last pump stage allows
air to flow into the pump chamber. This
prevents condensation and flushes the
pump clear.
Operation leads to:
- Increasing the ultimate pressure and
- Increasing the operating temperature.
The gas ballast valve is only provided as standard for MPC type diaphragm pumps. The fit-
ting into other pump types is an option or must be specified in the supply contract.
