1721-m4 Spec. Hydraulic Power Pump
Introduction
The1721 Spec. No. 60 pump is a high pressure hydraulic
power pump of extremely durable construction, simple to
operate and capable of delivering 10,000 psi.
This power pump has a built-in high volume / low pressure
pumping feature which gives fast approach ram action and
automatic changeover to low volume / high pressure when
pressure exceeds 200 psi. The pumping unit consists of a
one-piston radial-type capable of delivering 30 cubic inches
at 10,000 psi. The pump also contains a relief valve which
permits the motor to be shut off and restarted with load held
at any desired pressure up to 10,000 psi. This pump has
been pre-set at the factory for the desired pressure specifi-
cations to suit the compression machine model purchased.
Before attempting to adjust any valves (#1, 2, or 53), please
consult the factory first.
This power pump is equipped with an externally mounted
control valve which can be adjusted to vary the rate of
loading over a wide range to meet the specifications for
different specimens. For repetitious testing, the rate of
loading can be pre-set exactly according to specification.
A rapid traverse feature is included so that specimens can
be preloaded as rapidly as desired. The control valve has
a flow adjustment from 3 cubic inches per minute to 500
cubic inches per minute and can be easily adjusted by
turning the micrometer adjusting knob located on top of
the valve. Refer to Bulletin IM-711-B attached for further
operating instructions and parts on the flow control valve
and mounting plate.
The symbol above is used to call your attention

SAVETHESE INSTRUCTIONS
Additional copies of this manual are available upon request at no charge.
IMPORTANT SAFETY INSTRUCTIONS
• Do not connect the pump to any system or
system component other than those supplied by
Greenlee and rated at less than 10,000 psi
(68,950 kPa).
• Do not alter the internal high-pressure relief
valve setting.
• Do not use this pump in a hazardous environment.
Hazards include open flame and flammable liquids
or gases.
Failure to observe these warnings will result in
severe injury or death.
Electric shock hazard:
• Do not expose power tools to rain.
• Do not immerse the pendant
switch in water or other liquid.
Skin Injection Hazard:
High pressure oil easily punctures
skin causing serious injury, gangrene
or death. If injured seek medical help
immediately to remove oil.
Do not use fingers or hands to
check for leaks.
Depressurize hydraulic system
before disconnecting the hose.
•I nspect pump, hoses, couplers and fittings for wear
or damage. Replace worn, damaged or missing
components with Greenlee replacement parts.
• Do not twist, kink, curl, paint or cut the
hydraulic hoses.
• Wear eye protection when operating this
equipment.
• Disconnect the pump from the power supply,
rotate the release valve lever to AUTO RELEASE
and disconnect the hose from the ram and the
pump before performing any service.
Failure to observe these warnings could result in
severe injury or death.
• The pump is heavy, weighing up to 75 lbs. Follow
NIOSH work practices for manual lifting. If in
doubt, get help.
• Unplug pump when not in use and when changing
accessories.
• Do not use the hose to pull, lift, or carry the
equipment.
• Always work in an area providing good footing
and support.
• Keep work area well-lit, free of clutter, and dry.
Failure to observe these precautions could result in
injury or property damage.

1721-m4 Spec. Hydraulic Power Pump
Power
The power unit is equipped with a General Electric
one HP, 1725 rpm, 115/230 volt, single-phase, 60-cycle,
totally enclosed, fan-cooled, 15 min. 55˚C rise motor
and rotates in a clockwise direction. This is standard
equipment unless otherwise ordered.
For your protection, ground unit before using.
The electric motor is equpped with an approved
3-conductor cord and 3-blade grounding-type
attachment plug to be used with the proper
grounding-type receptacle, in accordance with the
National Electrical Code. The green-colored
conductor in the cord is the grounding wire, which
is attached to the metal frame of the unit inside the
housing and to the longest blade of the attachment
plug cap. A special grounding adapter is supplied
(except in Canada or for use above 150 volts) to
permit using two-wire receptacles until the correct
receptacle is installed. The green grounding wire
extending from the side of the adapter must be
connected to a permanent ground such as a
properly grounded outlet box, conduit or water
pipe, before plugging in the unit. (If extensions are
used, they should have sufficient rated capacity
and a properly connected grounding circuit.)
Operating Instructions
This pump is designed to operate at 10,000 psi
intermittently. For continuous service, as production
work, the pressure should not exceed 6,000 psi. (This
limitation is for motor protection only.)
Before operating pump, check the following to assure
proper service:
1. Check for proper power connections and for tight-
ness of hose connections before starting pump.
2. Check hydraulic oil with dipstick (54). Oil should be
within 1/2" of reservoir top.
3. Start motor and allow pump to idle a few minutes.
This will allow the hydraulic oil to work into the
moving parts and give prime to pump.

Never use synthetic fluids or fluids with poor
lubricating qualities, i.e., brake fluids, etc., as
permanent injury to the pump will result.
Eight quarts are required of which 6-1/4 quarts are
usable. A minimum of 1-3/4 quarts must be at the
bottom of the reservoir at all times during operation.
Be sure that your complete operation does not require
more than the usable amount of oil.
To refill or add oil to the reservoir, proceed as follows:
1. Remove vent unit from top of reservoir.
2. Add oil to within 1/2" of top of reservoir when ram is
retracted.
3. Install vent unit securely in place.
Check to see that vent unit is not clogged before
attempting to operate pump.
Draining Oil Reservoir. Unscrew and remove 3/8 inch
pipe plug (68) from side of pump base. Turn pump on its
side to drain all oil from reservoir. Be sure to replace
plug before refilling reservoir with oil.
Servicing Instructions
Filling Oil Reservoir. The oil reservoir must be kept
filled with a good grade of light hydraulic oil. Flushing System. As long as these pumps are used as
outlined in the operating instructions, long, trouble-free
performance can be expected. To maintain this perform-
ance, it is absolutely essential that dirt or other foreign
matter be kept out of the system as this is the most
common cause of hydraulic system failure. Therefore,
when opening up the pump for any reason, such as
making pipe connections, adjusting pressure or any
repair, be sure to exercise extreme care in cleanliness
and to use clean tools and cloths. If, at any time, dirt is
suspected to have found its way into the system, the
entire oil system should be flushed as follows:
1. Drain oil from reservoir.
2. Fill reservoir with any recommended flushing oil or
clean kerosene and operate pump. Work the control
handle back and forth several times during flushing
to wash all foreign particles from the control valve
unit.
Note: Do not operate pump for a very long time as
system is not designed to operate with flushing
oil or kerosene.
3. Drain flushing oil or kerosene from reservoir and
refill with new oil.
Motor Maintenance
The 1721-M4 Spec. No. 60 pump motor, when in need
of repairs, should be repaired by the manufacturer of
the motor or at one of the qualified GE Service Stations.

Minor HydraulicTrouble Chart
The hydraulic unit should be observed constantly for
out-of-the-ordinary performance and unusual noises.
If any of these are present, shut off pump and take
corrective steps immediately to avoid possible expensive
repairs later on. In most cases, a minor repair will solve
the problem but it is suggested that, if trouble continues,

the unit should be returned to the factory or to a qualified
service center for the proper repair. Under no conditions
allow unqualified personnel to attempt to repair the pump,
particularly the pump block unit, as serious, irreparable
damage may result.
If the above corrective measures fail to make the pump function, it is recommended that you send the pump back to
the factory or to a qualified service center.
