Pump Reliability

What’s the Problem?

Pumps left in Manual will overheat and destroy the seal.

On most pump starter panels, when the operator wants to start a pump, they use a Manual or Hand Start.  They switch the selector pump to Manual.  That is the operator’s only option.

The real problem happens when they leave the pump running in Manual.  Once the water level drops, the pump runs dry and the seal overheats and fails.

This is a frequent cause of failure of dewatering pumps.

What’s the Solution?

The SC10 supports a Start Pushbutton.  Give the Operator a Start Button so they don’t need to use a Manual Run.

On most starter panels the only way the operator can start the pump is to use the Manual Start.

With the SC10 you should connect a Start and, optionally, a Stop pushbutton.

The SC10 has Auto Start and Stop inputs.  When the Start pushbutton is pressed the SC10 will start the pump and, later, when the levels is pumped down, the SC10 will stop the pump normally.  So the damage is prevented.

Adjusting the Pump Stop Current in a Live Switchboard is not OK

Some dewatering pump controllers require the adjustment of the Stop Current to be made inside the starter panel / switchboard.  To adjust the stop current requires running the pump.  So with those controllers you need to work in a live switchboard.  This is not safe.  It is not acceptable.

What’s the Solution?

Using the SC10 you can use a pushbuttons on the starter door to adjust the Stop Current.

You can also provide current adjustment button on the door if you want.

With the SC10 you do not need to work inside the switchboard.

You can put adjustment pushbuttons on the door of the switchboard.

Or you can mount the SC10 through a cutout in the door.

A Guide to Designing a Starter for Safety and Reliability

I’ve created a guide to how to do best design a starter to maximise the benefits of the SC10.  You can find it on the 2iB SC10 page or download it right now.

You can, of course, use the SC10 without doing this, but these tips will help you to get better results.
