PumpThe CRN-SF pump is a non self-priming, vertical multi-stage centrifugal pump fitted with a Grundfos standardmotor.

The pump consists of a base and a pump head. Thepump body and the outer sleeve are fixed between thebase and the pump head by means of clamping plates.

The direction of rotation is opposite to that of the otherpumps, and the pump body is upside-down, thus givingthe opposite direction of flow of liquid.

The base, the pump head cover as well as vital pumpcomponents are made from stainless steel. The basehas in-line suction and discharge ports.

Pumped LiquidsThin, non-explosive liquids, not containing solid parti-cles or fibres. The liquid must not attack the pump ma-terials chemically.

When pumping liquids with a density and/or viscosityhigher than that of water, motors with correspondinglyhigher outputs must be used, if required.

Whether a pump is suitable for a particular liquid de-pends on a number of factors of which the most impor-tant are chloride content, pH value, temperature andcontent of solvents, oils etc.

Please note that aggressive liquids (e.g. sea water)may destroy the oxide film which protects the stainlesssteel and thus cause corrosion.

CR, CRNFor liquid transfer, circulation and pressure boosting ofcold or hot clean water.

CRN In systems where all parts in contact with the liquidmust be made of stainless steel, CRN pumps must beused.

MotorThe motor is a totally enclosed, fan-cooled, 2-poleGrundfos standard motor with principal dimensions inaccordance with the IEC and DIN standards.

Electrical tolerances according to IEC 34/EN 60034.

Mounting:– up to 4 kW: V 18,– from 5.5 kW: V 1

Insulation Class: F.Enclosure Class: IP 55, On request: IP 44 and IP 54.50 Hz Standard-Voltages: 3 x 200/346 V,

3 x 200-220/346-380V,3 x 220-240/380-415V,3 x 380-415∆ V,1 x 220-230/240 V,1 x 110/220 V.

Motors for other voltages are available on request.

Single-phase motors have a built-in thermal overloadswitch.

Three-phase motors must be connected to a motorstarter in accordance with local regulations.

Three-phase Grundfos motors from 3 kW upwards havea built-in thermistor (PTC) according to DIN 44082.

Max. Operating Pressure and Liq-uid Temperature for the Shaft SealThe actual operating range depends on the operating pressure, pump type, the type of shaft seal and the liq-uid temperature.

The following curves apply to clean water and water containing glycol.

Performance CurvesThe guidelines below apply to the curves shown on thefollowing pages:

1. Tolerances to ISO 2548, Annex B, if indicated.

2. The motors used for the measurements are stan-dard Grundfos motors.

3. Measurements were made with airless water at atemperature of 20°C.

4. The curves apply to a kinematic viscosity of υ = 1 mm2/s (1 cSt).

5. Due to the risk of overheating, the pumps shouldnot be used at a flow below the minimum flow rate.

The curve below shows the minimum flow rate as apercentage of the nominal flow rate in relation tothe liquid temperature.

Dimensioning Vertical Multistage Centrifugal Pumps

Selection of CR, CRN PumpPump SizeSelection 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 sucha way that the velocity of the liquid does not exceed 1to 1.5 m/sec.

EfficiencyIf the pump is always to operate in the same duty point,select a pump where this duty point coincides with thehighest efficiency.

In case of controlled operation or varying consumption,select a pump whose highest efficiency falls within theduty range representing the highest power consumpti-on, i.e. typically the duty range covering the greater partof the duty time.

NPSHIf the pressure in the pump is lower than the vapourpressure of the pumped liquid this may cause cavitati-on. To avoid cavitation, make sure that there is a mini-mum pressure on the suction side of the pump. Themaximum suction lift “H” in metres head can be calcu-lated as follows:

H = pb x 10.2 – 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 thehighest flow the pump will be delivering).

Hf = Friction loss in suction pipe in metres head(at the highest flow the pump will be deliver-ing.)

Hv = Vapour pressure in metres head.

Hs = Safety margin = minimum 0.5 metres head.

If the calculated “H” is positive, the pump can operateat a suction lift of maximum “H” metres head.

If the calculated “H” is negative, an inlet pressure of mi-nimum “H” metres head is required.

The pump must be able to fulfil the flow andpressure requirements.

Check that the highest efficiency falls withinthe marked duty range.

Check that the pump does not have and willnot be exposed to cavitation.

Dimensioning Vertical Multistage Centrifugal Pumps

MaterialThe material variant (CR/CRN) is to be selected on thebasis of the liquid to be pumped. The product rangecovers 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 page 64).

Shaft SealThe shaft seal is to be selected on the basis of liquidtemperature and max. pressure.

For other liquids than water, the chemical resistance ofthe materials - incl. seal face, seat and rubber compo-nents of the shaft seal - must be taken into account.

Parallel OperationIt may be an advantage to install a number of pumpsconnected in parallel instead of one big pump. Amongthe 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.

MiscellaneousIn case of liquid viscosity and relative density differentfrom that of water, motor size and pump performancemust be taken into account.

The material variant must be suitable for thepumped liquid (CR or CRN).

The shaft seal material and variant must besuitable for the pumped liquid.

In case the duty profile varies, consider theinstallation of two or more pumps in parallel.

General Data Vertical Mulitstage Centrifugal Pumps

List of Pumped LiquidsA number of typical liquids are listed below.

Other pump versions may be applicable, but thosestated in the list are considered to be the best choices.

The list is to be used as a guide only.

NotesD Often with additives.

E Density and/or viscosity differ from that of water. Al-low for this when calculating motor output and pumpperformance.

F Pump selection depends on many factors. Pleasecontact Grundfos.

G Temperature must be below boiling point.

2 Corrosion. The pumped liquid attacks all standardmetals. Use a shaft seal with no metal componentsin contact with the pumped liquid.

4 Poor lubricating properties. The pumped liquid hasso poor lubricating properties that dry running shouldbe avoided.

7 The pumped liquid is easily ignited.

8 The pumped liquid is flammable.
