A commercially built pump and engine unit will either be designed to prevent overloading, or it will have instructions with it, showing maximum operating time at full discharge. The pump casing shown above has a built-in well on the inlet side, for priming the pump. A centrifugal pump for weed spraying may also be primed (1) by mounting the pump below the water level in the supply tank, or (2) by addition of an exhaust- driven aspirator which will hold enough liquid to prim

NOTE: Neither centrifugal nor regenera- tive turbine pumps are positive dis- placement types, and no harm is done by closing the discharge while the pump is in operation. ii].
