1. Product introduction
This data booklet covers Grundfos CR and CRN
pumps with these nominal flow sizes:
• CR, CRN 95
• CR, CRN 125
• CR, CRN 155.
Fig. 1 CR, CRN 95-155
CR, CRN pumps are vertical multistage, centrifugal
pumps. The in-line design of the pumps enables
installation in a horizontal one-pipe system where the
inlet and outlet ports are in the same horizontal level
and have the same pipe dimensions. This design
provides a more compact pump design.
The pumps are available in various sizes and various
numbers of stages to deliver the flow and pressure
required.
CR, CRN pumps are designed for a variety of
applications ranging from the pumping of potable water
to the pumping of chemicals. The pumps are therefore
suitable for a wide diversity of pumping systems where
the performance and material of the pump meet
specific demands.
A CR, CRN pump consists of two main components:
the motor and the pump unit.
The pump unit consists of optimized hydraulics,
various types of connections, a sleeve, a pump head
and various other parts. See Construction, page 8.
CR, CRN pumps are available in various material
versions according to the pumped liquid.
CR pumps with ANSI/NSF 61 and ANSI/NSF 372
listing are available. FKM variants are only available
with ANSI/NSF 372 listing. See UL file MH24600 or
contact Grundfos.
Applications
The new CR, CRN range is suitable for numerous
applications identical to the applications which the
current CR, CRN pumps handle today. The following
applications are some typical examples.
Water supply:
• Filtration and transport water works
• Distribution from water works
• Pressure boosting of mains.
Industrial:
• Pressure boosting
• Process water transfer
• Boiler feed
• Cooling and air conditioning
• Firefighting systems
• District energy systems
• Special liquids transfer.
Water treatment:
• Filtration
• Brackish water reverse osmosis.
Pumped liquids
Thin, non-explosive liquids, not containing solid
particles or fibers. The liquid must not attack the pump
materials.
CR pumps are suitable for non-corrosive liquids and
are to be used for liquid transfer, circulation and
pressure boosting of cold or hot clean water.
CRN pumps are suitable for industrial liquids and are
to be used in systems where all parts in contact with
the liquid must be made of high-grade stainless steel.
