IDENTIFICATION OF "A" QUOTA.
To obtain the "B" quota value it is necessary to refer to the manufacturer's catalogue
specific to the cardan shaft used.
The choice of the most appropriate safety cone must be effected on the basis that "S"
(overlap) = A ÷ B (
≥
50 mm).
When two safety cones are available for the same pump model, both guaranteeing the
minimum overlap value, the shorter version is preferable in that this facilitates the fitting of
the cardan shaft.
