stream of each pump. Flow or pressure will
protect the pump by tripping the pump on
PAHH, FALL or PALL.
It can be done with one or more VFD, as
per below schematic diagram: Image 3 here
For zero flow control, you just need to set a
protection in SoftPLC code if the torque percentage is less than a value (e.g. 20%) and

motor is at certain speed. All of the auxiliary
pumps such as lube oil pump can be programmed in VFC softPLC. Hence costly control valves, flow transmitters can be removed
and the same for additional hook-up, cables,
JB, tray, etc.

Control of Air Flow
/Pressure with Fan
If built-in SoftPLC with VFD is used, you can
connect the pressure or flow sensor to VFD
and set internal PID controller to control the
fan speed with respect to the the set pressure
or flow rate. As VFD has DI, AI, you can have
a lots of interlocks for safety and similar to

Pump Genius Multiplex application for four pumps in parallel controlled by CAN communication interface.
