What the Air Hydraulic Pump Changes on a Press
The pump is what turns a press from a two handed job into a one footed one. Both hands come free for the bag and the parchment. Pressure then moves while you are watching the plate rather than while you are looking at a lever. Output reaches ten thousand PSI when the air supply is at a hundred PSI. Control runs through a two stage mechanism with an internal relief valve built in. That gives pump, hold and release all on the pedal. Pressure can be brought up in stages and held at a chosen point rather than jumping to maximum. Anyone who has worked a hand pump through a long session will recognise what is being removed here. The air inlet is a quarter inch NPT fitting and the oil port is three eighths inch NPT. It fits every Triminator TRP rosin press.
Sizing a Compressor Before This Reaches the Rosin Press
The manufacturer is unusually direct about the requirement, and it is the thing to settle before anything is ordered. The pump wants a minimum of five CFM at a hundred to a hundred and twenty PSI working pressure. That is the figure at pressure, not the optimistic number printed on the side of a small compressor at zero PSI. Triminator state plainly that an undersized compressor makes this pump slower than pumping by hand. That is a rare piece of honesty and a costly one to ignore. Check the compressor plate for its delivery at a hundred PSI and compare. Duty cycle matters as much as flow, because a pancake compressor that meets the figure briefly will spend a pressing session recovering. The pump itself measures roughly twenty-eight by sixteen by fourteen inches and weighs about twenty-five pounds. It sits on the floor beside the press rather than on the bench. Keep the air line out of the walking route.
