Series PSV: Special vertical axis pumps for conveying abrasive mixtures-sludge from sawmills work-shops, tile factories, etc. with cantilever shaft without stuffing box, vertical position of electrical motor to avoid risks of contact with pumped liquid, coupling through VEE-belts.
Series PGM: Special pumps for conveying metal shot mixtures to granite gang-saws. Vertical axis, with cantilever shaft without stuffing box, vertical position of motor with direct coupling through elastic joint.
