Position Qty. Description1 CM3-3 A-R-G-V-AQQV

Product No.: 96806823

Compact, reliable, horizontal, multistage, end-suction centrifugal pump with axial suction port and radialdischarge port. Pump materials in contact with the liquid are in high-grade 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 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 and outlet port are integrated in the pump sleeve. The inlet part, chambers anddischarge part are hold 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 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: FKM (fluorocarbon rubber)FKM has excellent resistance to oils and chemicals. Above 90 °C, FKM should only be used in mediawithout water.

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 does not incorporate motor protection and must be connected to a motor-protective circuitbreaker which can be manually reset. The motor-protective circuit breaker must be set according to therated current of the motor (I1/1).

An 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.
