Position Qty. Description1 CM3-5 S-R-I-E-AQQE
Product No.: On request
Compact, reliable, horizontal, multistage, end-suction centrifugal pump with axial suction port and radialdischarge port. The pump is self-priming and can create a suction lift of up to 4 m metres. Pumpmaterials in contact with the liquid are in stainless steel. The mechanical shaft seal is a specialdesigned, unbalanced O-ring seal. Pipework connection is via internal Whitworth pipe threads, Rp (ISO7/1).
The pump is fitted with a 1-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 pump can create a suction lift of 4 m metres in less than five minutes.Compared to other self-priming pumps, the CM pump offers lower noise level, higher reliability as wellas compactness and customised solutions.The pump is made of stainless-steel components (EN 1.4301 / AISI 304) and is thereforecorrosion-proof.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: 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 has built-in thermal protection (PTO current and temperature sensors) in accordance with IEC 60034-11and requires no further motor protection. The protection reacts to both slow- and quick-rising temperatures, e.g.constant overload and stalled conditions.
As the thermal protection incorporates automatic reset, the motor must be connected in a way whichensures that the automatic reset cannot cause accidents.
