region where you want to launch it.
In India, everyone will have to come
up to speed on air flow devices,
so vistronics is the next one for the
country followed by control fluid
pumps,” he added.

BorgWarner launched control fluid
pumps in Europe this year – a heavy
duty control coolant pump which
is basically a water pump with a
viscous mechanical device that
changes the drive from mechanical
to an electronically controlled one.
The pump can be fully modulated to
reduce parasitic losses.

Answering a question about the
possibility of its replacement by a
variable frequency electric motor,

Wagner said that “we see that trend in

passenger cars because of the power

requirements on the pump; for trucks,

medium and heavy duty, currently the

pump is only a mechanical or electro-

mechanical one. Moving forward, we

see potential in off-highway, buses

and tractors also. The main trend is

further electrification of our products,

new technology on the fan drive

side, introduction of coolant flow

devices like controlled pumps and

electromechanical ones. The first step

for any improvement is getting the fan

drives into vistronics – that is the first

optimisation. Then it is extended to

coolant-controlled fluid pumps. Not

much in it for BS-IV but there is for

BS-VI”.

Vistrionic Vs Viscous Fan

Drive

“The viscous comes out of the silicon

fluid. We have improved the product

parameters to get quicker response.

The key difference in the product

between the previous and this

generation is the bimetal drive of the

old version being replaced with an

electronic actuator that gets several

inputs from the ECU. This gives it

highly versatile functionality with a big

cost difference and 1.5 to 3% savings
