PumpThe CR pump is a non-self-priming, vertical multistagecentrifugal pump.

The pump consists of a base and a pump head. Thechamber stack and the outer sleeve are securedbetween the pump head and the base by means ofstaybolts. The base has suction and discharge portson the same level (in-line).

All pumps are equipped with a maintenance-freemechanical shaft seal.

Motor protectionSingle-phase motors have a built-in thermal overload switch.

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

Ambient temperature

Maximum 104 F [40 C].

If the ambient temperature exceeds +104 F [+40C]or if the motor is located 3,280 ft. [1000m] above sealevel, the motor output (P2) must be reduced due tothe low density and consequently low cooling effect ofthe air. In such cases, it may be necessary to use amotor with a higher output.

Example of operating and inlet pressuresThe values for operating and inlet pressures shownin the tables must not be considered individually butmust always be compared, see the followingexamples:

Example 1:The following pump type has been selected:CR 3-10 U-A-AMax. operating pressure: 232 psi [16 bar]Max. inlet pressure: 145 psi [10 bar]Discharge pressure against a closed valve: 139 psi[9.6 bar], see page 28.

This pump is not allowed to start at an inlet pressureof 145 psi [10 bar], but on the other hand at an inletpressure of 232 psi less 139 psi = 93 psi [16.0 less9.6 = 6.4 bar].

Example 2:The following pump type has been selected:CR 3-2 U-A-AMax. operating pressure: 232 psi [16 bar]Max. inlet pressure: 87 psi [6 bar]Discharge pressure against a closed valve: 27 psi[1.9 bar], see page 28.

This pump is allowed to start at an inlet pressure of87 psi [6 bar], as the discharge pressure against aclosed valve is only 27 psi [1.9 bar], which results inan operating pressure of 87 psi + 27 psi = 114 psi[6.0 + 1.9 = 7.9 bar]. On the contrary, the max.operating pressure of this pump is limited to 144 psi[7.9 bar], as a higher operating pressure will requirean inlet pressure of more than 87 psi [6 bar].

In case the inlet or operating pressure exceeds thepressure permitted, see Custom-built Pumps,page 45.

Operating range of the shaft sealThe actual operating range of the shaft seal dependson operating pressure, pump type, type of shaft sealand liquid temperature. The following curves apply toclean water and water containing glycol.For other liquids, see recommended shaft seals in theList of pumped liquids, page 41.In case of extreme temperatures, i.e. low temperatures down to -40 F [-40 C] or high temperatures up to +356 F [180 C]see Custom-built pumps, page 45.

Performance curves

The guidelines below apply to the curves shown onthe following pages:1. The motors used for the measurements are

standard Grundfos motors.2. Performance may vary based on motor selection.3. Measurements have been made with airless water

at a temperature of 68 F.4. The curves apply to a kinematic viscosity of

u = 1 cSt (1 mm/s).5. Due to the risk of overheating, the pumps should

not 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 to theliquid temperature.

The power curvesindicate pump inputpower per stage.

The NPSH curve is an averagecurve for all the variants shown.When sizing the pumps, add asafety margin of at least 1-1/2 ft.


13

Selection of CR, CRI, CRN pumps

Pump sizeSelection of pump size should be based on: Required flow and pressure at the draw-off point. Pressure loss as a result of height differences. Friction loss in the pipework.

It may be necessary to account for pressure loss inconnection with long pipes, bends or valves, etc.

Best efficiency at the estimated duty point.

EfficiencyIf the pump is expected always to operate at thesame duty point, select a pump which is operating ata duty point corresponding with the best efficiency ofthe pump.

In case of controlled operation or varying consump-tion, select a pump which best efficiency falls withinthe duty range representing the highest powerconsumption, i.e. typically the duty range covering thegreater part of the duty time.

MaterialThe material variant (CR, CRI, CRN) should beselected on the basis of the liquid to be pumped. Theproduct range covers three basic types. The CR, CRI pump types are suitable for clean,non-aggressive liquids such as potable water, oils,etc. The CRN pump type is suitable for industrial liq-uids (see List of pumped liquids, page 41).

For saline or chloride-containing liquids such as seawater, CRT pumps of titanium are available. Seeseparate data on CRT.

Pump connectionSelection of pump connection depends on rated pres-sure and pipework. To meet any requirement the CR,CRI and CRN pumps offer a wide range of flexibleconnections such as: Oval flange (NPT) ANSI flange PJE coupling FlexiClamp Other connections on request.

Shaft sealAs standard, the CR range is fitted with a Grundfosshaft seal suitable for the most common applications.

The following three key parameters must be takeninto account, when selecting the shaft seal: type of pumped liquid liquid temperature maximum pressure.Grundfos offers a wide range of shaft seal variants tomeet specific demands (see List of pumped liquids,page 41).

Inlet pressure and operating pressureIt should be checked whether the pressure conditionsare fulfilled.

The limit values stated on pages 10-11 must not beexceeded regarding... maximum inlet pressure maximum operating pressure.


15

Minimum inlet pressure - NPSHCalculation of the inlet pressure H is recommendedwhen ... the liquid temperature is high

the flow is significantly higher than the rated flow water is drawn from depths water is drawn through long pipes inlet conditions are poor.

To avoid cavitation, make sure that there is a mini-mum pressure on the suction side of the pump. Themaximum suction lift H in feet of head can becalculated as follows:

H = PB NPSHR Hf Hs Hv

PB = Barometric pressure in feet absolute.(Barometric pressure can be set to33.9 ft @ sea level).In closed systems, PB indicates the systempressure in feet.

NPSHR = Net Positive Suction Head in feet of head.(To be read from the NPSHR curve at thehighest flow the pump will be delivering).

Hf = Friction loss in suction pipe in feet of head. (At the highest flow the pump will be delivering.)

Hv = Vapour pressure in feet of head.(To be read from the vapour pressure scale. Hv depends on the liquidtemperature Tm).

Hs = Safety margin = minimum 1-1/2 feet of head.

If the H calculated is positive, the pump can operateat a suction lift of maximum H feet of head.If the H calculated is negative, an inlet pressure ofminimum H feet of head is required.

Check that the pump is not and will not be exposed tocavitation.
