By-Pass Valve Connection
- A by-pass valve should be places over discharge pipe just after pump and before
adjustment valve or outlet flange of pump if there is a case that pump will operate in
conditions that pump discharge valve is completely closed(that is with zero flow rate)
or almost closed (that is with very small flow rate). If such valve is not used and
pumps operates with closed valve for a long time, power which is provided by motor
will completely transform into heat energy and pass into discharged liquid. This may
cause over heating and abnormal failures in pump.
ELECTRICAL CONNECTIONS
- Electrical connections should be done by authorized electricians National
instructions, regulations and instructions of motor manufacturers should be obeyed.
- Power cables should absolutely be installed as not having contact with pipe
installation, pump and motor body.
