If the seals are worn so severely that the oil has leaked out and only
water mixed with mud and sand remains, the pump must be dis-
mantled for a complete overhaul.
Maintenance
Inspection at regular intervals and preventive maintenance should be
performed in order to reduce the number of functional troubles and to
avoid serious break-down of the pump unit. During normal opera-tion
service is not required until a reduction of the pump capacity is noted.
Inspection must be performed once a year, or 2000 operating hours.
When the pump is taken out of service for seasonal storage, a full
maintenance service should be carried out. Special attention should
be paid to the following points.
Cleaning and Removal of Lime Deposits
At a construction site the pump is often working in water mixed with
clay, concrete, lime, etc. When it is taken out of service it should be
flushed out in fresh water and fully inspected before it is put into
storage.
Hard and solid lime deposits are easily removed if the pump is fully
submersed in a vessel with a mixture of one part formic acid (HCOOH)
and 15 parts water.
Remove the pump after 5 minutes and flush it in fresh water. Some
deposits may remain, and a second treatment may be necessary. Not
all deposits may be removed.
Inspection of Shaft Seals
Check the condition of the shaft seal by inspection of the oil in the oil
chamber. Proceed as follows:
Remove base plate and outer casing. If it is difficult to remove the
casing due to deposits or build-up on the inside, the diffuser can be
removed together with the casing.
Unscrew the oil plug and drain the oil into a clean can and inspect it.
If the oil is clean and contains no water, the primary seal is free from
defects and can be used again. If the oil contains water and appears
”milky”, the seals must be changed and ball bearings checked. After
inspection and possible change of shaft seals new oil should be filled
into the oil chamber.
