Product No.: 96935411
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: 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 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.
