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 may be installed in a horizontal or vertical position or optimum unctioning o
suction and delivery valves. The round reservoir may be used horizontally and it is
advised that the breather and sight glass be interchanged and/or the reservoir rotated
to allow the breather to remain uppermost. The suction and return tubes inside the
reservoir may also be rotated to ensure luid is taken rom, and returned to, the bottom
o the reservoir in any given position.
The air inlet connection can be rotated at 90 º and piping o not less than 3/8” bore
should be used. 1/2” should be used i the pump is to be run at higher speeds or
greater lows.
It is advisable to use or maintain:
•Hydraulic oil having viscosity o 150 to 250 SSU
•Oil temperature 32º F to 150º F
•Air temperature 40º F to 100º F
•Room temperature 40º F to 100º 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 will be advisable to it an air ilter/regulator unit having minimum low capacity o 50
sc m with an air pressure gauge 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.

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 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, which is 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 sealless spool valve. By regulating the
compressed air supply pressure rom 30 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. This operation
must be carried out by qualified personnel.
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.

Oil pressure can be determined by regulation o the compressed air, bearing in mind
multiplication ratio pre-selected or the pump itsel .
The models are: P820 RATIO 1:5
P820 RATIO 1:10
P820 RATIO 1:20
P820 RATIO 1:30
P820 RATIO 1:40
For instance, when supplied with compressed air at 80 psi, the P820-5 will produce oil
pressure o 80 x ratio, 400 psi. It should be remembered that actual e iciency produced
by the pump is slightly less than given by the above theoretical calculation. This
di erence will not be noticed by a hydraulic gauge.
Having connected the compressed air supply at a low pressure, allow the pump to
operate slowly until primed and oil comes through to the oil output port. Now shut o
the air supply to the pump and securely connect the hydraulic circuit. Switch on the air
supply again and allow the pump to run in order to bleed any air out o the hydraulic
circuit.
Pump eatures:
•Standard mani olds and subplates are available with various con igurations o SAE
threaded ports or output and return as well as D03 inter aces.
•Optional rotation o the 1/2” NPT air inlet elbow in our positions.
•The pump itsel works automatically and operates by way o an integral valve.
•The pneumatic drive section has graphite illed seals or minimum riction, no
lubrication requirement and long li e.
•The hydraulic section comprises an alloy steel pump casing, hard chrome plated
piston rod and bronze illed seals.
•The suction side o the pump is equipped with a spring-loaded check valve. A
spring-loaded outlet ball type check valve is incorporated in the hydraulic piston.

Maintenance
Periodically release the condensation rom the air ilter. Replace the hydraulic oil every
1500 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.
