General Data 

Pumped Liquids 

Thin, non-explosive liquids, not containing solid particles 

or fibres. The liquid must not attack the pump materials 

chemically. 

When pumping liquids with a density and/or viscosity 

higher than that of water, motors with correspondingly 

higher outputs must be used, if required. 

Whether a pump is suitable for a particular liquid depends 

on a number of factors of which the most important 

are chloride content, pH value, temperature and 

content of solvents, oils etc. 

Please note that aggressive liquids (e.g. sea water) 

may destroy the oxide film which protects the stainless 

steel and thus cause corrosion. 

CR, CRN 

For liquid transfer, circulation and pressure boosting of 

cold or hot clean water. 


In systems where all parts in contact with the liquid 

must be made of stainless steel, CRN pumps must be 

used. 

Motor 

The motor is a totally enclosed, fan-cooled, 2-pole 

Grundfos standard motor with principal dimensions in 

accordance with the IEC and DIN standards. 

Electrical tolerances according to IEC 34/EN 60034. 

Mounting: 

–upto4kW: V18, 

–from5.5kW: V1 

Insulation Class: F. 

Enclosure Class: IP 55, On request: IP 44 and IP 54. 

60 Hz Standard- 

Voltages: 3 x 220-255/380-440 V, 

3 x 220-277/380-480V, 

3 x 380-480 Δ=V, 

1 x 110-127/220-240 V. 

Motors for other voltages are available on request. 

Single-phase motors have a built-in thermal overload 

switch. 

Three-phase motors must be connected to a motor 

starter in accordance with local regulations. 

Three-phase Grundfos motors from 3 kW upwards have 

a built-in thermistor (PTC) according to DIN 44082. 


Max. Operating Pressure and Liquid 

Temperature for the Shaft Seal 

The actual operating range depends on the operating 

pressure, pump type, the type of shaft seal and the liquid 

temperature.

containing glycol.

Dimensioning 

Selection of CR, CRN Pump 

Pump Size 

Selection of pump size should be based on: 

• consumption pattern, 

• highest possible flow and pressure (peak values), 

• economy. 

As a rule of thumb pipes should be dimensioned in such 

a way that the velocity of the liquid does not exceed 1 

to 1.5 m/sec. 

Efficiency 

If the pump is always to operate in the same duty point, 

select a pump where this duty point coincides with the 

highest efficiency. 

In case of controlled operation or varying consumption, 

select a pump whose highest efficiency falls within the 

duty range representing the highest power consumption, 

i.e. typically the duty range covering the greater part 

of the duty time. 

NPSH 

If the pressure in the pump is lower than the vapour 

pressure of the pumped liquid this may cause cavitation. 

To avoid cavitation, make sure that there is a minimum 

pressure on the suction side of the pump. The 

maximum suction lift “H” in metres head can be calculated 

as follows: 

H=pb x10.2–NPSH–Hf –Hv –Hs pb = Barometric pressure in bar. 

(Barometric pressure can be set to 1 bar). 

In closed systems, pb indicates the system 

pressure in bar. 

NPSH = Net Positive Suction Head in metres head 

(to be read from the NPSH curve on at the 

highest flow the pump will be delivering). 

Hf = Friction loss in suction pipe in metres head 

(at the highest flow the pump will be delivering.) 

Hv = Vapour pressure in metres head. 

Hs = Safety margin = minimum 0.5 metres head. 

If the calculated “H” is positive, the pump can operate 

at a suction lift of maximum “H” metres head. 

If the calculated “H” is negative, an inlet pressure of minimum 

“H” metres head is required.

Dimensioning 

Material 

The material variant (CR/CRN) is to be selected on the 

basis of the liquid to be pumped. The product range 

covers two basic types. 

• CR is suitable for clean, non-aggressive liquids such 

as potable water, oils, etc. 

• CRN is suitable for clean, slightly aggressive liquids 

such as salt water, acids, etc. (see list of pumped 

liquids). 

Shaft Seal 

The shaft seal is to be selected on the basis of liquid 

temperature and max. pressure. 

For other liquids than water, the chemical resistance of 

the materials - incl. seal face, seat and rubber components 

of the shaft seal - must be taken into account. 

Parallel Operation 

It may be an advantage to install a number of pumps 

connected in parallel instead of one big pump. Among 

the advantages are for instance: 

• adaptation to the required duty point in systems with 

varying flow profile, 

• increased reliability of supply as only part of the 

system capacity is affected in case of pump failure. 

Miscellaneous 

In case of liquid viscosity and relative density different 

from that of water, motor size and pump performance 

must be taken into account. 


The material variant must be suitable for the 

pumped liquid (CR or CRN).

General Data 

List of Pumped Liquids 

A number of typical liquids are listed below. 

Other pump versions may be applicable, but those 

stated in the list are considered to be the best choices. 

The list is to be used as a guide only. 

Continued on next page 

Notes 

Vertical Mulitstage Centrifugal Pumps 

D Often with additives. 

E Density and/or viscosity differ from that of water. Allow 

for this when calculating motor output and pump 

performance. 

F Pump selection depends on many factors. Please 

contact Grundfos. 

G Temperature must be below boiling point. 

2 Corrosion. The pumped liquid attacks all standard 

metals. Use a shaft seal with no metal components 

in contact with the pumped liquid. 

4 Poor lubricating properties. The pumped liquid has 

so poor lubricating properties that dry running should 

be avoided. 

7 The pumped liquid is easily ignited. 

8 The pumped liquid is flammable.
