looks like a bespoke powerpack for a specific application, A look on Sara's website shows some hydraulic loading bay levellers and scissor lifts.
Although the power pack is rated at 210 bar and 3.7 lpm, I suspect the applications are not in constant use. A fully enclosed motor and pump without a cooling system would not be suitable for a continuous use application.
Likely the ports are just an internal manifold to allow multiple connections, perhaps to two cylinders - easy to check with an air line.
Looking at the SWL on the item, it is likely off a loading bay/dock leveller. As above, it would low duty cycle - to level up the dock to the lorry that's just pulled up and maybe occasional tweaks as the lory rises or falls as the goods are loaded or unloaded.
We design, supply and install tailored and high quality loading bay solutions, either individually or as part of multiple applications. | sara LBS | Loading Bays
