- Pump bearings are shipped from the factory as being filled with grease which will be
enough for one year.
- Before first start of pump, bearings should be checked whether there dirt has
entered into it during shipment and installation. If bearings are dirt they should be
completely be cleaned and greased again.
- If pump has waited before installation for a long time (more than 6 months), new
grease should be inserted into bearings.
-Be sure that there is liquid in liquid tank and/or liquid source
- Be sure that pump and suction pipe is completely filled with liquid.
ATTENTION!
Never let pump run in dry conditions.
Determination of Rotation Direction
- BTKF-K type pumps rotates in clockwise direction when you look from
clutch towards pump. This direction is shown with an arrow in pump body.
Pump is operated for a short while and checked whether it rotates in correct
direction. If protection guard is uninstalled during this operation, it should
immediately be installed after this operation.
Starting Pump
- Check that suction valve is open and discharge valve is closed.
- Close the circuit breaker and start the motor.
- Wait motor to reach full speed. (Wait motor to pass delta in motors operation with
star-delta)
- Observe the ammeter in panel and slowly open discharge valve. (If discharge pipe
is empty in first start, do not open discharge valve completely and open in controlled
way by controlling that value in ammeter is lower than motor rated values.)
-After valve is completely opened control the value which is read from ammeter
whether it is same with the value at operational point. If the ammeter value is less
than operational value adjust it by closing the valve. If it is greater check the
installation and static height.
ATTENTION: If any of following problems occur while pump operates in nominal
speed; pump should immediately be stopped and trouble should be eliminated.
1) Pump operates with over vibration.
2) Pump and motor connection bearings have over temperature.
3) Pressure is not enough.
