Hello, I hope, here in the forum is someone who knows a little about hydraulics. I have a fairly old pneumatic hydraulic lifting platform of the brand Grazia, Italian factory. The pneumatics is simple-acting and housed in a separate container with hydraulic oil and is defective, I fear, because of lack of spare parts also no longer to repair. My question: can I probably connect to the pressure hose of the lifting platform any hydraulic pump if pressure (1 90 bar) and oil volume (5 liters) match? On the market there are cheap electrohydraulic pumps for 230V, 2.2 kw. Still cheaper would be 12 V tipper pumps, but they would have to pull a lot of current strength after my consideration. For suggestions I am very grateful greetings Georg
