Frequently asked questions
What pressure do HiP T-Series pumps reach?
The T6000 series reaches 58,000 psi (4,000 bar), the T7500 68,000 psi (4,690 bar). There are 18 models with ratios from 32:1 to 900:1, for pressures from 3,200 psi (230 bar) upwards.
What is the difference between a T-Series pump and a power pack?
The pump is the pumping unit alone. The power pack supplies it already assembled with air filter, regulator, gauges, on/off valve, release valve and lines, pressure-tested and ready to connect to compressed air.
Is lubricated air or another power supply needed?
No. T-Series pumps do not require lubricated air: the power pack runs on unlubricated compressed air only, up to 6.9 bar (5 bar for models T7568 and T7557).
Which fluids and seals are available?
Power packs are designed for water and oil. Seals are NBR as standard, EPR on request; FKM is available from models T6025 and T7525 towards the lower pressures, FFKM from T6016 and T7516.
How long does it take to receive price and availability? Can I rent the unit?
A technician will reply within 24 working hours. Units for testing with liquids are also available for weekly or monthly rental, with delivery throughout Italy and technical support for the whole duration.
