5- START UP / SHUT DOWN
5.1- Preparation
5.1.1- Lubrication control
• The bearings of SDS type pump are always lifetime grease lubricated. Lifetime grease lubricated
bearings are maintenance-free.
5.1.2- Venting and priming
• Make sure that the pump and suction pipes are completely filled up with water. There is no problem
for the pumps which have positive suction head. If there is a valve on suction line, it must be opened
and air taps are loosened to enable the water replaces air in the pump, until it is completely full with
water.
Make sure the pump never runs dry.
5.1.3- Checking the direction of rotation
• SDS type pumps rotate in clockwise when it is looked from coupling to the pump. This direction is
already indicated on the pump by an arrow. Check this by switching the pump on, then off again
immediately. Fit the coupling guard back in place if you took it out.
5.2- Start Up The Pump
• Check if the shut off valve in the suction line is open.
• Switch on the circuit breaker and run the motor.
• Wait until the motor reaches the full speed (on star-delta running motors wait until it switches on
delta).
• Pump doesn’t deliver any water,
• Pump doesn’t deliver enough water,
• Flow is going down,
• Discharge pressure is not enough,
• Driver overloaded,
• Vibration on pump,
• High noise level,
• Bearing overheating.
ATTENTION
The pump should be shut down at once and the trouble should be corrected if the pump
is running at its rated speed and found any of the following faults:
