ABSTRACT:
A pump for medium consistency suspensions (e.g. 6-15%), such as paper pulp, simultaneously pumps and degasses the suspension. A common shaft mounts a fluidizing impeller and a vacuum pump impeller and a common wall with gas exhaust passageways is disposed between the fluidizing pump housing and vacuum pump housing. Gas separated from the suspension flows through the gas passageways in the common wall, through the vacuum pump, past the vacuum impeller, and is expelled out the opposite side of the vacuum pump from the gas inlet passageways. A pressure responsive valve provides make-up air to the vacuum pump if the vacuum pulled is too strong, to prevent suspension from being pulled through the vacuum pump. A liquid inlet supplies liquid in the vacuum pump to define a liquid ring, the inner periphery of the ring defined by the expelled gas outlet.
