Product No.: 97513426

Compact, reliable, horizontal, multistage, end-suction centrifugal pump with axial suction port andradial discharge port. Pump materials in contact with the liquid are in stainless steel. Themechanical shaft seal is a special designed, unbalanced O-ring seal. Pipework connection is viainternal 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 lowbase plate, 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 deliveryand are 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 hydraulicparts from the pump side. The inlet and outlet port are integrated in the pump sleeve. The inletpart, chambers and discharge part are held together by four staybolts and a retaining flange.

The pump is fitted with an unbalanced O-ring seal with a rigid torque transmission system. It has afixed seal driver ensuring a reliable rotation of all parts. The dynamic secondary seal is an O-ring.

Primary seal:- Rotating seal ring material: Aluminium oxide (alumina)- Stationary seat material: Carbon graphite, resin-impregnated

Carbon graphite against alumina is a good all-round seal for not too demanding applications. Thecorrosion resistance is often limited in water to a range between pH 5 and pH 10. Usage in liquidsabove +90 C is not recommended. The seal can handle dry-running conditions for short periods.

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 cannotbe dismantled.

Motor

1/7



The motor is a totally enclosed, fan-cooled motor with principal dimensions to EN 50347. Electrical tolerancescomply with EN 60034.

The motor efficiency is classified as IE2 in accordance with IEC 60034-30.The motor does not incorporate motor protection and must be connected to a motor-protectivecircuit breaker which can be manually reset. The motor-protective circuit breaker must be setaccording to the rated current of the motor (I1/1).

An installation indicator is fitted to the motor fan cover. Based on the motor cooling air, it indicatesthe direction 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 anyduty point. Grundfos CUE offers a range of variable speed drives. Please find more information inGrundfos Product Center.
