The pumps are designed to provide full performance
down to a level of A inches above the bottom of the
strainer.
At a liquid level between A and B mm above the
bottom of the strainer, the built-in priming screw will
protect the pump against dry running.
Note: MTR(E) 32, 45 and 64 pumps have no priming
screw.
