Pumping chemically aggressive or toxic gas-

es and vapors

➨

Avoid explosive conditions when compressing explo-

sible and flammable substances/mixtures. In such in-

stances, use inert gas for gas ballast.

Attention: The gas ballast of the diaphragm pump is

permanently connected to the system.

Implement special protective measures to protect per-

sonnel, pump, and environment.

• Install a cold trap (see ”Accessories”, pg. 39), if the

thermodynamic conditions of the application are such

that vapors could condense in the rotary vane pump.

Wait until the pump has reached its operating temper-

ature before connecting it to the vacuum system.

Before switching off, allow the pump to run for a few min-

utes, initially with the rotary vane pump‘s gas ballast valve

open and then with the gas ballast valve closed, after the

pump has been isolated from the vacuum application.

Prevent internal condensation, transfer of liquids or dust.

The pump requires regular inspection and maintenance.
