Note:
A pump with a single-phase motor is shown in this gure. The motor shown in this gure
is not representave of the motor used on the E1/E2M18 pumps with Item Numbers
A34317984 and A36317984. On these pumps, Cable-gland/Amphenol connector posion
and On/O switch are transposed, with Cable-gland/Amphenol connector posion being
an IEC60320 16-20 Amp socket.
2.4 Gas-ballast
When using the pump with high vapour throughputs, the gas-ballast facility should be
used to prevent condensaon of the vapours inside the pump. The condensates will
contaminate the oil, will cause performance to deteriorate and may cause corrosion of
the pump mechanism.
Air (or an inert gas) can be introduced into the pump mechanism through the gas-ballast
control (Figure: General view of the pump on page 11).
