PRODUCT DESCRIPTION
BVA Hydraulics Double Acting Air Hydraulic Pump is
engineered to meet most industrial standards for Performance
and Safety. It is an air hydraulic pump with 4-way valve.
It’s unique hydraulic circuit allows quick displacement of
hydraulic fluid under no load conditions and easy pumping
in loaded conditions. Pump supplies compressed hydraulic
fluid to compatible double-acting cylinder, anywhere that
10,000 PSI of fluid pressure is needed. It is suited for plant
maintenance, production, bolting, vehicle repair, and any task
that requires hydraulic pressure from air input. Special skill,
knowledge and training may be required for a specific task
and the product may not be suitable for all the jobs described
above. Unsuitable applications would include applications
that call for a device to move, level or support persons,
animals, hazardous materials, mobile homes/ dwellings in
general, mirrors and/or plate glass, and/or to connect/secure
hatches, components, etc. between bulkheads. The user
must ultimately make the decision regarding suitability of the
product for any given task and assume the responsibility of
safety for himself and others in the work area.
WARNING: To reduce the risk of personal injury and/or
property damage, ensure that the rated working pressure of
each pressurized attachment be equal to or greater than the
rated working pressure developed by the hydraulic pump.
Always check connections before using. Alteration
of these products is strictly prohibited. Use only those
adapters and attachments provided and approved by the
manufacturer.

• Study, understand, and follow all
instructions provided with and on this
device before use.
• All WARNING statements must be
carefully observed to help prevent
personal injury.
• No alteration shall be made to this
device.
• Always wear protective gear when
operating hydraulic equipment.
• Keep hydraulic equipment away from
flames and heat. Hydraulic fluid can
ignite and burn. Do not operate if
leaks are detected.
• Crush Hazard. Keep hands and feet
away from loading area. Avoid pinch
points or crush points that can be
created by the load, cylinder, or any
equipment of system.
• To avoid crushing and related injuries:
NEVER work on, under or around
a lifted load before it is properly
supported by appropriate mechanical
means. Never rely on hydraulic
pressure alone to support load.
! WARNING
HYDRAULIC PUMPS
• The user must be a qualified operator familiar with the
correct operation, maintenance, and use of pumps. Lack of
knowledge in any of these areas can lead to personal injury.
• Do not exceed rated capacity of the pump or any equipment
in the system.
• Never attempt to lift a load weighing more than the capacity
of the cylinder.
• Burst hazard exists if hose or connection pressure exceeds
rated pressure.
• Do not subject the pump and its components to shock
loads.
• Inspect pump, cylinder, hoses and connections before each
use to prevent unsafe conditions from developing. Do not
use if they are damaged, altered or in poor condition. Do
not operate the system with bent or damaged coupler or
damaged threads.
• Never hold or stand directly in line with any hydraulic
connections while pressurizing.
• Use gauge or other load measuring instrument to verify load.
• Never attempt to disconnect hydraulic connections under
pressure. Release all line pressure before disconnecting
hoses.
• Use only approved accessories and approved hydraulic fluid.
• Never attach ANY component not authorized by manufacturer.
• Always ensure that the chosen application is stable to work
on and around.
• Do not connect to application which can return more oil to
the reservoir than the pump reservoir can hold.
• Do not connect pump to hydraulic system powered by
another pump.
• This device is not suitable for use as support device! As
the system load is lifted, use blocking and cribbing to guard
against a falling load.
• All personnel must be clear before lowering load or
depressurizing the system.
• Never try to disassemble a hydraulic cylinder, refer repairs
to qualified, authorized personnel.
HYDRAULIC HOSES & FLUID TRANSMISSION LINES
• Avoid short runs of straight line tubing. Straight line runs
do not provide for expansion and contraction due to
pressure and/or temperature changes.
• Reduce stress in tube lines. Long tubing runs should be
supported by brackets or clips. Before operating the pump,
tighten all hose connections with proper tools. Do not
overtighten. Connections should only be tightened securely
and leak-free. Overtightening can cause premature thread
failure or high pressure fittings to burst.
• Should a hydraulic hose ever rupture, burst or need to be
disconnected, immediately shut off the pump and release
all pressure. Never attempt to grasp a leaking pressurized
hose with your hands. The force of escaping hydraulic fluid
can inflict injury.
• Do not subject the hose to potential hazard such as fire,
sharp objects, extreme heat or cold, or heavy impact.
• Do not allow the hose to kink, twist, curl, crush, cut or bend
so tightly that the fluid flow within the hose is blocked or
reduced. Periodically inspect the hose for wear.
• Do not pull, position or move setup by the hose.
• Hose material and coupler seals must be compatible with
hydraulic fluid used. Hoses also must not come in contact
with corrosive materials such as battery acid, creosote-
impregnated objects and wet paint. Never paint a coupler
or hose.
• FAILURE TO HEED THESE WARNINGS MAY RESULT IN
PERSONAL INJURY AS WELL AS PROPERTY DAMAGE.

OPERATION
To reduce the risk of personal injury and/or property
damage, Hydraulic connections must be securely fastened
before building pressure in the system. Release all system
pressure before loosening any hydraulic connection in the
system.
Always monitor pressure, load or position using
suitable equipment. Pressure may be monitored by means of
an optional manifold and gauge. Load may be monitored by
means of a load cell and digital indicator. Correct application
position can only be determined by the operator of the
equipment.
1. Connect air supply to the 1/4” NPT air nipple.
2. Remove manifold plug, connect to hydraulic hoses and
suitable application.
3. Shift the valve to desired position. There are three positions
available, refer to Figure 2 on below for the flowpath.
4. After shifting the valve, press on the foot pedal until desired
pressure, load or position is reached. Always monitor
pressure, load or position using suitable equipment.
Pressure may be monitored by means of optional
manifolds and gauges (contact BVA Hydraulics). Load
may be monitored by means of a load cells and digital
indicators.
Note. Do not continue to operate pump after cylinder plunger
is fully extended or retracted.
5. Release the foot pedal will stop the pump flow.
Note: Both air input ports use a 1/4 NPT air nipple (not
included). It is recommended to install an inline air filter
upstream from the pump to provide clean, lubricated air.
