Hydropneumatic Tank Control Systems

Well pumps and booster pumps work with pressure tanks to maintain a consistent pressure range in the system. The pressure tank maintains the pumping-cycle rate required to avoid overheating the pump motor and premature motor failure. Hydropneumatic tanks work best with an air cushion of ¼ to ½ the tank capacity. This cushion decreases as

Concrete for Pumping| Concrete Construction Magazine

Feb 01, 1973 · Experience has shown that gradation of both fine and coarse aggregate is often the most important factor in determining the pumpability of a concrete mixture, although other mix design characteristics also contribute. If gradation is poor, the excess of some aggregate sizes or efficiency of others will produce voids in the mix that permit the water to escape from it under pumping pressure.
