BVA Hydraulic Hand Pumps are engineered to meet most industrial standards for performance and safety. These pumps, P8701 and
P8701M have a unique two-stage hydraulic circuit which allows quick displacement of hydraulic uid under no load conditions and easy
pumping in loaded conditions. These lever operated pumps supply compressed hydraulic uid to compatible applications i.e. rams,
presses, spreaders, compactors and crimping machines, anywhere that 10,000 PSI of uid pressure is needed. Special skill, knowledge
and training may be required for a specic 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/herself and others in the work area.
WARNING: Always check connections before using. Alteration of these products is strictly prohibited. Use only those adapters
and attachments provided and approved by the manufacturer.
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

SET UP
WARNING: The pump’s maximum working pressure is
10,000 PSI. Make sure that all hydraulic equipment such as
cylinders, hoses, couplers and etc. used with this pump are
rated at 10,000 PSI operating pressure or more.
1. Setthepumponahardatsurface,i.e.aworkbench.Remove
theoilllerscrewfoundonrearendcaptocheckuidlevel.
Correctuidlevelisevenwiththeoilllerscrewhole.
2. Depressurize system by opening release valve counter-
clockwise, but no more than 2 full turns. Then carefully
remove the threaded plug on oil outlet port, and connect
3/8” NPTF hydraulic connection to oil outlet port, i.e.
coupler, gauge adapter, hydraulic hose etc. Ensure all uid
ports and thread connections are clean before connect.
For model P8701M:
The pump comes with a 4-way valve to use with double acting
cylinder. Connect two hoses: connect one hose from the
pressure port of the pump to the pressure port of the cylinder;
connect the other hose from the retract port of the pump to the
retract port of the cylinder.
If using on single acting cylinder, the valve needs to be
changed to 3-way valve. Consult with BVA Technical Service
888-332-6419
NOTICE: Always secure threaded connections with non-hardening
pipe thread compound. Take care not to introduce compound into
port orices. Tighten securely to prevent accidental removal of
components while in use.
3. Install a pressure gauge in-line from the pump for better control
and safety purpose.
NOTICE: It is recommended to use BVA ttings, gauge adapter
and guage.
4. Tighten securely to prevent accidental removal of components
while in use.
5. Checkforleaksinsystemandrepairbyqualiedpersonnelas

OPERATION
WARNING: ALWAYS monitor pressure, load or position
using suitable equipment. Pressure may be monitored by
means of an optional manifold and gauge (contact BVA
Hydraulics). 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. Remove the threaded plug, then connect the pump to
suitable application.
2. Ensure the oil level is correct and the system ttings and
connections are leak free before operating the pump.
CAUTION: NEVER operate pump with release valve closed
and disconnected from application. If operated in this
condition, the hose and connections become pressurized.
This increases burst hazard. Damage may occur to pump
and its components
3. For model P8701:
A. Close release valve by turning it clockwise. Finger tight
ONLY. Using tools on release valve can damage it and
cause the pump to malfunction.
B. Handle until desired pressure, load or position is reached.
C. Pressure will maintain until the release valve is opened.
D. To retract application, turn the release valve knob slowly
counterclockwise (never more that 2 full turns).
4. For model P8701M:
Use the control valve lever to control the direction of hydraulic
oil ow, refer to Figure 4a on page 5. Handle until desire
pressure, load or position is reached.
WARNING: Operate double-acting cylinder only when
both hoses are connected to the pump. If on coupler is left
unconnected, high pressure will build behind the coupler
which could cause personal injury and/or equipment damage.
5. Under no load or 1st stage condition, the pump operates in
high ow for rapid advance. When load is contacted, the pump
will automatically shift to the 2nd stage for building pressure.
When pump pressure reaches approximately 290 psi, you
must momentarily stop pumping and raise the handle to shift
to the high pressure stage. After the pump shifts, pumping
takes less effort.
NOTICE: operate pump handle at slower speed during the high
ow 1st stage to ensure the pump delivers maximum oil volume.
