High self locking nuts with nylon in material to high resistance R=700/800 N/mm2. Self locking and normal ring-nuts.
Components’ kit to realize hydraulic cylinders constituted from: guinding head in hydraulic cast iron G25-UNI 5507, pistons realized in steel C 43 or UNI CF 9S MnPb 28 and high self locking nuts UNI CF 35 SMn Pb 10.
Anterior and back linkages for cylinders realized in steel C 43 for anterior threaded terminal and Fe 510 C/D for the back linkages to weld. Accurate mechanical workmanships guarantee an elevated squareness between the holes and the threads with tolerances from 0,2 to 0,05 mms. The holes for the pins are in tolerance H7 and H8. These components can have employed on the hydraulic cylinders and they can also be submitted to heavy jobs.
The vane pumps distribuited by ARPI are built with bodies in aluminium and hydrulic cast iron. The flows to disposition go from 2 to 195 lts. for 1000/rpm for the single pumps and 313 lts. for 1000/rpm for the double versions. Good performances, low sound level, ease of maintenance and possibility of variation of the sense of rotation are some characteristics of our pumps. The particular drawing of the hydraulic balancing reduces the wear and it eliminates the lbearing loads. This line of pumps is in two solutions: the models for industrial application BHS and VS and those for the mobile use BHP and VK. The speed ranges from 600 to 2500 rpm. The maximum pressure varies from 175 to 275 Bar. The sound level has contained in range of 69-78 dBs (A) to 1500/rpm and 140 Bar. Some types are interchangeable with some foamous multinational Houses also for what it concerns the cartridges, the shafts etc., similar VICKERS and DENISON.
A triple vane pump of an unique versatility is also built that can join in the third stadium gear pumps and piston pumps, and vane pumps, etc, with possibility of innumerable versions. Our pumps are prompt in stock for delivery in 24/48 hours.
Hydraulic vane motors with displacement by 9 cm3/rev. to 220 cm3/rev, they are interchangeable with DENISON..
Also we can provide genuine Bosch-Rexroth axial piston pumps with variable displacement for any application.
On request we project Motor Pump Integrated Units, also with special electric motors.
