Air- hydraulic pumps are extremely light and versatile. Tests results show how exceptionally reliable and suitable they are for the most difficult uses thanks to their unique design (series SA, MA, HA, TA, VA, made of plastic material outside and metal alloy inside). There are six multiplying factors: 19:1, 60:1, 122.1, 196:1, 278:1, 345:1 for maximum oil pressure values respectively of 80, 350, 700, 1000, 1500, 2100 bar. All the pumps (version KA excluded) have a maximum pressure valve non adjustable from the outside. The outward pressure can be adjusted varying the inward air pressure. The four basic version are: • MLP0 with P and T outlets, to be used with on-line valves. • MLP1 with Cetop 3 plate • MLP2 with three-way valve (with control pedal) for single acting cylinders • MLP4 with four-way valve (with hand lever) four double acting cylinders. A series of options can be added to the basic version to complete the pump action. See table page 57.
