Position Qty. Description1 CM15-4 A-R-A-E-AQQE

Product No.: 97516582

Compact, reliable, horizontal, multistage, end-suction centrifugal pump with axial suction port and radialdischarge port. The shaft, impellers and chambers are made of stainless steel. The inlet and dischargeparts are made of cast iron. The mechanical shaft seal is a special designed, unbalanced O-ring seal.Pipework connection is via internal Whitworth pipe threads, Rp (ISO 7/1).

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

Further product detailsPump and motor are integrated in a compact and user-friendly design. The pump is fitted to a low baseplate, making it ideal for installation in systems where compactness is important.The state-of-the-art design and materials of the shaft seal ensure high wear resistance, improvedsticking and dry-running capabilities and long operating life.Servicing the pump requires no special service tools. Service parts are in stock for quick delivery andare available as kits, single parts or bulk. Service videos are available on www.youtube.com.

PumpA combination of a stop ring and a Nord-lock® washer secures a tight and reliable fixation of theimpeller spacing pipes to the splined pump shaft. It is possible to remove and fit the hydraulic parts fromthe pump side. The inlet part, chambers and discharge part are hold together by four staybolts.

The pump is fitted with an unbalanced O-ring seal with a rigid torque transmission system. It has a fixedseal driver ensuring a reliable rotation of all parts. The dynamic secondary seal is an O-ring.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: EPDM (ethylene-propylene rubber)EPDM has excellent resistance to hot water. EPDM is not suitable for mineral oils.

The pump shaft is connected to the motor shaft through a left thread and tight fit. The shaft cannot bedismantled.

MotorThe motor is a totally enclosed, fan-cooled motor with principal dimensions to EN 50347. Electricaltolerances comply with EN 60034.

The motor efficiency is classified as IE2 in accordance with IEC 60034-30.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.

Position Qty. DescriptionAn installation indicator is fitted to the motor fan cover. Based on the motor cooling air, it indicates thedirection of rotation of the motor. The motor is fitted with a directional sticker.

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.
