VARIABLE SPEED PUMP SYSTEM INTRODUCTION
THEORY OF OPERATION
The variable speed pump controls out going variable pressures of the water for
better equipment operation by maintaining a constant pressure on the system.
The pump is capable of producing 26 GPM or more at a minimum of 30 PSI.
The variable speed pump system is controlled by a VFD controller mounted to
the motor. The unit is set to stop at the set pressure if there is no flow. The
electronics will look at the pressure but will not try to start the motor until it sees
pressure drop.
INSTALLATION
The following guidelines should be met at installation.
1. Mount the variable speed booster pump system on a firm level foundation
by using bolts through the .50 dia. pre drilled holes in the unistrut channel.
2. To insure sufficient cooling of motor and electronics, the following must be
observed:
Place the pump in such a way that sufficient cooling is ensured.
The temperature of the cooling air must not exceed 40 degrees C.
Cooling fins and fan blades must be kept clean.
3. The size of the inlet water supply piping should be 1”.
4. The size of the outlet piping from the variable speed pump system should
be 1”.
5. Follow all local plumbing and electrical codes. The pump is 220-230 volt
single-phase.
Warning : All electric supply circuits must be interrupted before
working in the pump terminal box. Never make any
connections in the pump terminal box unless the
electricity supply has been switched off for at least
5 minutes.
6. A blade or service disconnect isn’t provided. It must be installed. The
pump must be connected to an external all-pole mains switch with a
contact separation of at least 3 mm in each pole according to IEC 364.
Warning : The pump must be earthed and protected against indirect
contact in accordance with national regulations.
