This unit can be used with spherical vessels of 50, 100 and 200 liters capacity and cylindrical vessels of 20, 30, 50 and 100 liters capacity.
Shaft seals are designed to operate either with vacuum in the vessel or at pressures up to the maximum recommended for the vessel in question. Where circumstances demand, special seals can be supplied, for example flushed seals for use when working with poisonous gases.
