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 compatible with pump component
materials (that is, liquids that will not attack the pump).
4. Make sure plumbing is adequate to handle system
pressure.
5. Periodically perform maintenance inspection on pump
and system components.
6. 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
Maximum Ambient Temperature ........................... 104°F (40°C)
Liquid Temperature Range .......................................5°F to 250°F
(–15°C to +121°C)
Maximum Permissible
Operating Pressure Curves .......................................See Figure 4
Maximum Inlet Pressure: .........................................See Table III
Table III shows the maximum permissible inlet pressure.
However, the actual inlet pressure plus the pressure when
the pump is running against a closed valve must always be
lower than the Maximum Permissible Operating Pressure.
Electrical Data ............................................. See motor nameplate
Dimensions and Port-to-Port Lengths ......... See Figures 2A, 2B,
3A and 3B
Danger: Warns about hazards that will cause
