I repeat this message annually… no, monthly. No matter the manufacturer; the majority of all pumps do NOT come from the factory ready to start up.
The pump will require oil to be added to the bearing housings.
The impeller clearance must be determined and set for the fluid temperature. The direction of rotation should be ascertained and matched to the phase rotation on the motor driver (you must do this step with the coupling removed).
The driver will need to be aligned to the pump. When I tell people that they should align their pump nine times, I get some funny looks, but allow me to explain. Yes, the alignment may have been performed in the factory, but the very second the unit was moved for transport the alignment was lost. You will need to recheck the alignment when the unit is installed and leveled, again when the base is grouted, again after the piping is installed and again after the pump has been running up to temp.
The mechanical seal will need to be set after the above steps are completed.
Finally… please understand that most manufacturers do not install the coupling at the factory because it will just need to be removed for all the above reasons.
Be ready to complete these items, so you look like a pump professional.
