Carefully read and follow all safety instructions in this 

manual or on pump.

 This is the safety alert. When you see this symbol on your 

pump or in this manual, look for one of the following signal 

words and be alert to the potential for personal injury.

The word NOTICE indicates special instructions that are 

important but not related to hazards.

To avoid serious or fatal personal injury and possible property 

damage, carefully read and follow the safety instructions.

  1. Install pump according to all code requirements.

 2. Compare pump nameplate data with desired operating 

range.

 3. Pump only liquids that are compatible with pump 

component materials (that is, that will not attack the 

pump). For liquids other than water, consult chemical 

compatability charts.

  4. If in any doubt about chemical compatability with the 

pump, consult the factory for further information.

  5. Do not pump strong acids or caustics with this pump.

  6. Make sure plumbing is adequate to handle system 

pressure.

 7. Periodically perform maintenance inspection on pump 

and system components.

  8. Wear safety glasses at all times when working on pumps.

INSPECT THE SHIPMENT:

The vertical multistage centrifugal in-line pump has been 

carefully inspected and packaged to assure safe delivery. Inspect 

the pump and fittings and report to the carrier any items that are 

damaged or missing.

CONFIRM THAT YOU HAVE THE RIGHT PUMP:

APPLICATIONS AND OPERATING RANGES:

Pentair multistage in-line centrifugal pumps are designed for 

liquid transfer, circulation, and pressure boosting of hot or cold 

clean water or other thin, nonexplosive liquids, not containing 

solid particles or fibers, which will not chemically attack the 

pump materials.

Typical applications include:

  • Municipal water supply and pressure boosting

  • Boiler feed and condensate systems

  • Cooling water systems

  • Irrigation

  • Fire fighting
