Introduction
This handbook is intended to give the operator the basic instructions or the use and
maintenance o the pump. The air hydraulic pump operator must read this
handbook be ore putting the pump into operation. A ter correctly installing the
pump, keep this manual stored in a sa e place. I you have di iculty in
understanding any part o this handbook, contact Hydronic Corporation. Regular
servicing and correct use o the pump are undamental in obtaining optimum
per ormance over its li e. When contacting our service center, speci y the pump
model and serial number. This will help us to respond quickly and e ectively.
Guarantee
Hydronic pumps are guaranteed both or the quality o materials used and or
overall design. The warranty runs or six months o normal use at eight hours per day
and ive days per week. The warranty itsel does not cover seals or de ects arising
out o operating with unsuitable luids or at pressures above the speci ied maximum.
The guarantee cannot cover pumps that may have been tampered with. De ective
goods must be sent to Hydronic Corporation at Farmington Hills or to the distributor
covering the area, reight pre-paid in either case. Any pump returned to us must be
accompanied by a ull written description o such aults or de ects as have been
discovered. Please also ensure that the pump’s serial number is attached to the
paperwork.

Installation Guide
Pumps should be installed in a vertical position or optimum unctioning o suction
and delivery valves. The recommended minimum size or the suction line is 3/8”
bore, or the pressure line is ¼” bore and or the airline is ½” bore. It is also
recommended that pumps should be used with a hydraulic directional control
valve. The ollowing standard conditions are advised:
•Hydraulic oil having viscosity o 150 to 250 SSU
•Oil temperature 32º F to 150º F
•Air temperature 40º F to 120º F
•Room temperature 40º F to 120º F
Obstructive icing o the silencer may occur under certain temperature/humidity
conditions. This can be remedied by the addition o anti reeze oil or pneumatic
equipment to a mist lubricator.
Compressed Air ystem
It is strongly recommended that an air ilter/regulator/gauge unit having minimum
low capacity o 50 sc m is itted in order to ensure the pump has su icient air
energy to work correctly and provide the hydraulic per ormance you expect.
Hydraulic ystem
Valves, pipes, hoses and accessories should all correspond to maximum working
pressure o the pump used and be o a size that will ul ill low requirements. Bear in
mind the minimum o 3/8” bore or the suction line.
Application
Hydronic air driven hydraulic pumps are designed or operating oil hydraulic circuits
and to cover the widest range o requirements to the best advantage.
The pump itsel operates quite simply, using a well-known pressure intensi ication
principle. A piston with a large sur ace area is actuated by compressed air.
Attached to it is a piston with a smaller sur ace area and driven in a hydraulic
chamber generating a high level o hydraulic pressure. The continuous pumping
action is produced by the compressed air being switched by a special valve
assembly and timing mechanism. By regulating the compressed air supply pressure
rom 20 psi to 100 psi, the maximum hydraulic pressure can be adjusted by the ratio
o the pump used. As the hydraulic load o the circuit increases and the oil pressure
rises, the pump will slow down and eventually stop. In this way, the maximum load o
the circuit will be maintained without air consumption.

torage
I the pump is to be kept out o use or a long period, clean the pump in general
and drain the oil rom the tank. Cover the pump and store it in a dry, well-protected
place. It is advisable to wrap the pump in a plastic ilm. To put back into service,
check all parts, ill tank with oil and try the pump out to ensure that it working
properly. Quali ied personnel must carry out this operation.
Disposal
I the pump is to be scrapped, treat as a special type o waste. Dismantle it and
divide it into materials o the same type and dispose o them in accordance with
the local laws and regulations in your state or area.

Oil pressure can be determined by regulation o the inlet compressed air pressure
and bearing in mind the multiplication ratio pre-selected or the pump itsel .
The models are: P826-65 RATIO 1:65
P826-120 RATIO 1:120
P826-170 RATIO 1:170
P826-265 RATIO 1:265
P826-345 RATIO 1:345
It should be remembered that the action o the air/oil piston assembly is powered in
both directions by the compressed air. The single acting oil piston causes the suction
o oil through the suction valve only when the piston assembly is traveling upward.
When the piston assembly is traveling downward, oil is pushed out into the system
through the output check valve.
Having connected the compressed air supply at a low pressure (perhaps only 20
psi), allow the pump to operate slowly until ully primed and a steady low o oil
comes through to the output port. Now shut o the air supply to the pump and
securely connect the rest o the hydraulic circuit to the outlet port. Switch on the air
supply again and allow the pump to run in order to bleed any air out o the rest o
the hydraulic circuit. The system pressure can then be adjusted by means o the air
regulator.

Maintenance
Periodically release the condensation rom the air ilter. Replace the hydraulic oil
every 1,500 hours or whenever the oil is polluted.
Warning: Remember that repair work can only be made when pneumatic and
hydraulic pressure has been released and you are sure that no pressure remains in
the circuit.
Delivery of the pump
Transport
All the material shipped, including the detached parts, has been thoroughly
checked be ore being consigned to the orwarding agent. The pump is shipped in
double corrugated cardboard packaging which assures protection o the product.
Unpacking
On receipt o the product, open the packaging and remove the pump. Take care
not to damage any part o the pump. Make an initial check on the pump or
damage in transit. In case o damage or i in doubt, do not use the pump and
contact Hydronic Corporation or your distributor. The packaging [plastic bags,
expanded polystyrene, nails, screws, wood, etc.] must not be le t within reach o
children since they are potential source o danger. Be sure to dispose o pollutant or
non-biodegradable materials in the correct way. Materials must be disposed o in
accordance with the local, national and ecological laws in orce.
