Total ink pumped per day per pump (gal)
Total ink used per day
CFM of air per gallon of ink
Total CFM = CFM/gal x total ink used per day
Horsepower (hp) = total cfm ÷ 4
Daily power consumption (kW/hr) = total hp ÷ 7.46
Energy cost = daily power consumption x kW rate

Gallon of oil per gallon of ink
Total oil = gallons of oil per gallon of ink x total ink used per day
Horsepower = (maximum oil pressure x total oil) ÷ (1714 x 0.85)
Daily power consumption (kW/hr) = total hp ÷ 7.46
Energy cost = daily power consumption x kW rate

A. Hydraulic power pack – Consists mainly of oil reservoir,
electric motor and variable volume/pressure-compensated
hydraulic pump.
B. Supply and return lines – Supplies high pressure oil to the
hydraulic ink pump and returns the used oil.
C. Hydraulic regulator and flow control – Controls the
pressure and flow of oil to the hydraulic motor which, in
turn, controls the outlet pressure and cycle rate of the
ink pump.
D. Hydraulic motor – The Viscount II uses a controlled
volume of oil, at a specific pressure, to duplicate the fluid
flow and pressures in a pneumatic system. The controlled
oil is then circulated back to the power pack for reuse.
Note: Pneumatic motors exhaust the compressed air into
the atmosphere after cycling the pump.
Kilowatt rate of $0.06 is used in calculation

CHOOSE HYDRAULIC AND SAVE!
Unlike pneumatic, hydraulic motors continually reuse the oil required to cycle the motor,
making hydraulic technology the most efficient solution for pumping ink!
