Position Qty. Description1 CRN 120-2 A-F-A-V-HQQV

Product No.: On request

Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). Pumpmaterials in contact with the liquid are in high-grade stainless steel. A cartridge shaft seal ensures highreliability, safe handling, and easy access and service. Power transmission is via a rigid split coupling.Pipe connection is via DIN flanges.

The pump is fitted with a 3-phase, fan-cooled asynchronous motor.

Further product detailsSteel, cast iron and aluminium components have an epoxy-based coating made in a cathodicelectro-deposition (CED) process. CED is a high-quality dip-painting process where an electrical fieldaround the products ensures deposition of paint particles as a thin, well-controlled layer on the surface.An integral part of the process is a pretreatment. The entire process consists of these elements:1) Alkaline-based cleaning.2) Zinc phosphating.3) Cathodic electro-deposition.4) Curing to a dry film thickness 18-22 my m.The colour code for the finished product is NCS 9000/RAL 9005.

PumpA long split coupling connects the pump and motor shaft. It is enclosed in the motor stool by means oftwo coupling guards. The long coupling makes it possible to replace the shaft seal without removing themotor from the pump.

The motor stool connects the pump head and motor. The pump head has a combined 1/2" priming plugand vent screw.

The pump is fitted with a balanced O-ring seal unit with a rigid torque-transmission system. This sealtype is assembled in a cartridge unit which makes replacement safe and easy. Due to the balancing,this seal type is suitable for high-pressure applications. The cartridge construction also protects thepump shaft from possible wear from a dynamic O-ring between pump shaft and shaft seal.Primary seal:

• Rotating seal ring material: silicon carbide (SiC)• Stationary seat material: silicon carbide (SiC)

This material pairing is used where higher corrosion resistance is required. The high hardness of thismaterial pairing offers good resistance against abrasive particles.Secondary seal material: FKM (fluorocarbon rubber)

1/13


Position Qty. DescriptionFKM has excellent resistance to oils and chemicals. Above 90 °C, FKM should only be used in mediawithout water.

The shaft seal is retained in the pump head by a cover and screws. It can be replaced without removingthe motor.

The chambers and impellers are made of stainless-steel sheet. The chambers are provided with aPTFE neck ring offering improved sealing and high efficiency. The impellers have smooth surfaces, andthe shape of the blades ensure a high efficiency.

The pump has a stainless-steel base mounted on a separate base plate. The base and base plate arekept in position by the tension of the staybolts which hold the pump together. Both the inlet and theoutlet side of the base have two pressure gauge tappings. The pump is secured to the foundation byfour bolts through the base plate. The flanges are fastened to the base by means of locking rings.

MotorThe motor is a totally enclosed, fan-cooled motor with principal dimensions to IEC and DIN standards.The motor is flange-mounted with free-hole flange (FF).Motor-mounting designation in accordance with IEC 60034-7: IM B 5 (Code I) / IM 3001 (Code II).Electrical tolerances comply with IEC 60034.The motor efficiency is classified as IE3 in accordance with IEC 60034-30-1.The motor has thermistors (PTC sensors) in the windings in accordance with DIN 44081/DIN 44082.The protection reacts to both slow- and quick-rising temperatures, e.g. constant overload and stalledconditions.Thermal switches must be connected to an external control circuit in a way which ensures that theautomatic reset cannot cause accidents. The motors must be connected to a motor-protective circuitbreaker according to local regulations.The motor can be connected to a variable speed drive for adjustment of pump performance to any dutypoint. Grundfos CUE offers a range of variable speed drives. Please find more information in GrundfosProduct Center.
