Handling hoses and starting transfer of chemical from tanker trucks or isotainers to the bulk storage tanks is difficult with high density fluids such as H3PO4 or fluids that have high propensity for outgassing such as H2O2. Explain how transfer pumps are primed and tankers unloaded efficiently but without stressing chemicals. Carefully consider pump location and potential suction height of dry piping from ISO-containers, drums/IBCs and bulk storage tanks.
