4. MAINTENANCE
3. OPERATION
When the pump has been pumping corrosive media, we recommend to perform any possibly
planned maintenance work immediately in order to prevent corrosion of the pump.
After maintenance is completed and reconnect the power of 3 phase pump,
recheck the pump rotationdirection.
Do not reuse o-ring and seals if they are damaged
.

MaintenanceFrequency
The plan shown in the below Table details the routine maintenance operations necessary to
maintainthe pump innormal use
.
More frequent maintenance may be required if the pump is used to process corrosive or abrasive
gases and vapors; in these circumstances, we recommend that you replace the pump seals every
year. Ifnecessary, adjust the maintenanceplanaccordingtoyour experience
.
Whenyou maintainthe pump, use WASspares andservice kits;
there contain all of the components necessary to complete maintenance operations successfully.
The Item Numbers ofthe spares and kits are givenin Section7.1.
* WSA provides 2 kinds of Service kits(Repair kits)
‘
Minor Repair Kit
is for the general use for overhaul and consists of various metal and rubber
parts. It contains mainly disposable parts which need to be periodically replaced.
‘
Major Repair Kit
contains major parts(ex.vanes) which should be replaced for repair process in
addition to all Minor parts.(refer sec 7.1)

Safety Guide
WARNING
Obey the safety instruction given below.
If you do not, you can cause personal injury and property damage
Allow the pump to cool to a safe temperature before you start maintenance work
.
WARNING
Disconnect the electrical connection before disassembling the pump.
Make absolutely sure that the pump cannot be accidentally started.
(pull the main plug)
A suitably trained and supervised technician must maintain the pump
.
Obey your local and national safety requirements
.
If the pump has pumped harmful substances, ascertain the nature of hazard and take adequate
safety measures
.
CAUTION
When disposing of used oil,
you must observe the applicable environmental regulation.

3. Decontamination of Oil
As the oil is gradually contaminated during operation by dissolved gases and vapors, the degas
process is necessary to prevent corrosion of the pump. Allow the pump to continue operating with
inlet port closed and gas ballast control open until the oil is free of condensedvapors.
It is recommended to leave the pump being operating in this mode for about 30 min after finishing
the process. To attain the ultimate pressure, close the gas ballast after this process.
4. Switching Off & Shutdown
You can simply switch off to stop the pump, under normal circumstances.
*
When motor is switched off while the gas ballast is open, the system pressure can be risen slowly.
(Close the gas ballast to maintain vacuum level.)
If the pump is to be shutdown for an extended period after pumping aggressive or corrosive media
or if the pump has tobe stored, proceed as follows;
①
Drain the oil through oil drain-plug.
②
Add clean oil until the oil-level is at the H mark and let the pump operate for some time
.
③
D
rain the oil again and add clean oil until the oil level is at the H mark.
④
Seal the connectionports.
WARNING
When pumping harmful substance, take adequate safety precautions.
