    7 the eh-hv series pumps require a flooded suction or pre-primed condition before operation. Flooded suction (mounting the pump below the level of liquid in the supply tank) is recommended for proper operation of high viscosity pumps. (see figure 1) these pumps are not designed to be self-priming. T...
