Separators

Assembling the hose nozzle with union nut at the inlet and at the outlet:

Take the hose nozzle with attached compression ferrule and union nut out of the

round bottom flask and put onto inlet / outlet connection.

Tighten the union nut by hand until you can feel the stop. Then tighten an addi-

tional 1/4 rotation with an open-ended wrench size 17 for final installation.

Catchpots:

The catchpot at the inlet prevents droplets and particles from

entering the pump.

Lifetimes of diaphragms and valves are enhanced.

Improves vacuum in case of condensation.

Use the condensate separator (catchpot AK) at the outlet.

No draining of condensate back into the pump, controlled

recovery of condensate.

Both catchpots are coated with a protective layer to prevent

disintegration in case of breakage or implosion.

Assemble the catchpots at the inlet and at the outlet using

joint clips.

During operation

Vent and dispose of

potentially dangerous gases or vapours at the outlet of

the pump appropriately.

Due to the high compression ratio, the pump might generate overpressure at the

outlet. Check pressure compatibility with system components (e.g., exhaust tub-

ing or exhaust valve) at the outlet. Ensure that the pump outlet is neither blocked

nor restricted.

Maximum ambient temperature: 40 °C

Check the maximum temperatures, if installing the pump in a cabinet or a hous-

ing. Make sure ventilation is adequate, especially if the ambient temperature is

elevated.

• If the pump is installed at an altitude of more than 2000 m above mean sea

level, check compatibility with applicable safety requirements, and adopt suitable

measures. There is a risk of the motor overheating due to insufficient cooling.

• Check compatibility with the

maximally permitted pressure at outlet and the

maximum pressure difference between inlet and outlet ports.

Do not start the pump if the

pressure difference between inlet and outlet ports

exceeds max. 16.0 psi (1.1 bar). Attempts to start the pump at higher pressure dif-

ference may cause stalling and damage of the motor.

If pumping condensable vapours (water vapour, solvents, etc.), let the pump run with

gas ballast to help purge any condensation in the pump.

Prevent internal condensation, transfer of liquids or dust. The diaphragms and valves

will be damaged, if liquids are pumped in significant amounts.

Check the pump regularly for external soiling and deposits. Clean the pump if neces-

sary to avoid an increase of the pump’s operating temperature.
