Rugged, Service-Proven
and Virtually Maintenance Free
A variety of EPD Products hydraulic
pumps is offered for various liquid output pressure up to 33,500
psi
(2311
bar).
EPD
Products
pumps service water, oil and most corrosive chemicals. EPD
Products pumps are rugged, service-proven and virtually maintenance-free.
The EPD Products positive-displacement type pump converts
air inlet pressure to hydraulic output pressure. The pump uses
low pressure air to act on a large area piston to produce high
hydraulic pressure with a small area piston.
In operation, the
EPD Products pump reciprocates rapidly until the system liquid
pressure nears the desired level, then
slows to a stop when the liquid pressure equals or balances
the air pressure. This liquid-air pressure balance is maintained
indefinitely in a holding condition with minimal energy consumption
and with no increase in fluid temperature or parts movement.
In
contrast, a motor-driven pump in a holding condition must continue
to operate to maintain a pressure level. Excess liquid
must be bypassed or recirculated back to the reservoir, resulting
in energy-loss, heat build-up, and the need to bypass components
and a larger reservoir.
The EPD Products pump is efficient
in operation and simple in design, providing the user with
cost-effective and energy-saving
benefits for many industrial and research applications when
compared to other types of hydraulic pumps.
The EPD
Products air-driven pump offers economical advantages for the
pressure testing of hoses, pipes, valves, fittings
and other hydraulic vessels and products. The time-saving and
performance advantages offered by EPD Products pumps allow
routine production testing to be converted from tedious hand-pump
methods to automatic and precision testing methods.
The EPD Products air-driven pump delivers high pressure
liquids required by production machinery for holding, clamping,
forming, shearing, punching, etc. Example of application is
a hydraulic press where long holding cycles are necessary or
where the work stroke is short and a high force is required.
High and low volume EPD Products pumps can be combined
to produce a combination of high speed and high force at low
cost.
Because
EPD Products air-driven pumps are relatively small, they
can be installed directly on individual machines or test
equipment in several or separate locations as direct power
sources. Pumps so mounted eliminate need for a central power
system, long plumbing runs and excess hydraulic power capacity.
Unlike motor-driven
pumps, EPD Products air-driven pumps are non-arcing and
non-sparking, and can be used safely in
hazardous or confined areas.
EPD Products
pumps do the same job as other air-driven pumps but with fewer
parts and seals, and therefore less maintenance
