Please check following points immediately after receiving the product.
If the defect in the product is found, please report details to CHEONSEI or local distributor.
We ll take care of it promptly.
Is specification correct as ordered?
Is there any missing parts?
Is there any visible damage caused by vibration or shock during transport?
Reciprocating pump has a peculiar pulsation which cause vibration of piping and overfeed phenomena.
Air chamber will be used to solve such problems caused by pulsation.
According to the conditions of the piping, the discharge rate may be excessive or the pumping liquid
may be continuously leaked in spite of stopping the pump which is caused by overfeed or siphon
phenomena. The back pressure valve is for preventing such things.
When the discharge pressure increases to more than a setting point due to choking the valve with
debris or closing the valve, the safety valve will open automatically to relieve the pressure. Relief valve
prevents pump and piping from damages.

The applicable pump models may vary depending upon the piping condition.
Note) H.P : High Pressure

Wear suitable protective clothing(gloves, mask, goggles, working clothes, & etc.) during repair & maintenance.
Before repair & maintenance, release pressure & drain liquid in the piping.
In case of Air Chamber, In case of use for some liquids reacted to oxygen or moisture, be cautious
because the air is filled in the air chamber(example: deoxidating agent, deoxidant, antioxidant, & etc.)
In case of PVC material, if possible, please be careful that the operating pressure does not exceed 5 bar.
In case of PVC material, avoid the direct rays of the sun because PVC material is deteriorated
with UV rays and, if possible, put a protective cover on it in order to prevent damage from impact by a sharp
object
In case of PVC material, we recommend replacement of air chamber every three years.
It is impossible to reduce the pulsation extremely by itself. Therefore it is necessary to install Control Valve or
Back Pressure Valve on the discharge side of Air Chamber in order to make a resistant to the piping. It is
also necessary to adjust the resistance according to flow rate in order to minimize the pulse rate.
Every time flow rate of metering pump is adjusted, need to adjust the resistance to the suitable
resistance by Control Valve.
Air is contained in the Air Chamber. Air in the Air Chamber is dissolved into the liquid and air
decrease little by little because air is constantly contacting the liquid. If air in the Air Chamber
decrease, pulsation will be bigger.
Therefore, supplement air into the Air Chamber periodically.
Pay attention to the liquids reacted to oxygen or moisture because the air is filled in the air chamber.
When pumping the liquids contains slurry or the crystalloid liquid, clean the inside of piping after stop of
operation.
Install the Air Chamber at the close range
within 1~2 meters from the metering
pump.
Fix the Air Chamber with support.
For safety, do not install a valve between
the metering pump and the Relief Valve .
Make sure that the inlet/outlet direction of
the BV and RV is not installed reversely.
Install the pressure gauge on the
discharge piping
Install the pipe & valve for draining
certainly.
Take precautionary measures against the
freezing of the liquid in winter

When the needle of the pressure gauge is swayed over twice as wide as the usual one or
vibration occur in the piping or the pulsation of the discharge side becomes bigger, should
supplement air into the Air Chamber
Weekly inspection is recommended
If the operating pressure exceeds 5 bar, the dissolution speed of the air into the liquid will be
accelerated and the function of air chamber cannot be maintained. At this situation, should
supplement air into the Air Chamber frequently
When supplementing air into the Air Chamber,
please keep the following procedures
After stop of pump, close both front valve and
rear valve of the Air Chamber.
Slowly unfasten the upper plug and drain the
air. When the air is completely drained, fasten
upper plug.
Unfasten the lower plug and unfasten the
upper plug again in order to drain the liquid.
Fasten the upper & lower plug firmly, when the
flow of liquid comes to a stop.
Open both front valve and rear valve of the Air
Chamber.
In case of dangerous liquid, install valves
instead of a plug, together with a drain pipe.
If the pressure gauge should be installed, use
Union.
Setting pressure of Back Pressure Valve and Relief Valve is set at our factory with the clean water.
So you have to readjust it according to actual flow rate & actual pressure, if necessary.
If you want to adjust setting pressure, unfasten the housing cap counterclockwise and, if you fasten the
valve guide(rear) & the control bolt clockwise, setting pressure will get higher. On the contrary, if you
unfasten the valve guide(rear) & the control bolt counterclockwise, setting pressure will get lower.
Adjust setting pressure by watching the pressure gauge on the piping while the pump is working.
If the setting pressure is correctly adjusted, fasten the housing cap.
If you want to remove foreign substance from the valve or change a diaphragm, close the front piping of
the valve and drain the liquid.
Then, unfasten the bolts and disassemble the housing& the diaphragm from the valve.
After removing the foreign substance, make sure that you re-assemble the diaphragm in such a way that
the PTFE-coated side of the diaphragm faces the main body .
