AIR CONNECTION
The air pressure should not be in excess 7 bars.The pump should be
provided with the air supply at such pressure and flow to achieve
desired performance.When the airsupply line is solid piping, use a
short length of fl
exible hose not less than ½"in diameter between the
pumpand the piping to reduce strain to thepiping. The weight of the
air supply line, regulators and filters must be supportedby some
means other than the airinlet cap. Otherwise, unsupportive weight
may result in damageto the pump. A pressure regulatingvalve should
be
installed to insureair supply pressure does not
exceedrecommended limits.
WARNING If the size of air connection is
smaller than the pump supply port, the
pump will not be able to provide the air
required so, it will not perform properly.
AIR VALVE LUBRICATION
The air distribution valve and the pilot valve are designed to operate
without lubrication. This is the preferred modeof operation. In regard
to anticipated practice or inferior air quality, it is likely include
lubrication oil into the compressed air. The pump air system will
operate withproperly lubricated compressed airsupply. Proper
lubrication requires theuse of an airline lubricator system to deliver
one drop of SAE 10 oil for every 10 liters/sec. of airconsumed by the
pump at the operation point.For better determination of the mixing
ratios, see the performance curves provided for the pump.
AIR LINE MOISTURE
Water in the compressed air supply might give rise to problem like
freezing of the water or icing in the discharge line thatcausethe pump
to cycle erratically or stopoperating.These problems might be
removed by using a point-of-use
air dryer to supplement the user’s
airdrying equipment.The air drying equipment will removes the water
andalleviates problems like, freezing or icing.
AIR INLET AND PRIMING
Before operating the pump, turn the air supply valve at about 1/2 or
3/4 of a turn.Afterthe pump primes, the air valve can be opened to
increase air flow as desired.. If opening of the valve increases of the
reciprocating frequency without increase in air flow, then it means
that the pump operates under cavitation. In such cases, the
valveshould be closed slightly to obtain themost efficient air flow to
pump flowratio.
