Position Qty. Description1 CME25-2 A-R-A-E-AQQE

Product No.: 99077767

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, fan-cooled, permanent-magnet, synchronous motor. The motorefficiency is classified as IE5 in accordance with IEC 60034-30-2.The motor includes a frequency converter and PI controller in the motor terminal box. This enablescontinuously variable control of the motor speed, which again enables adaptation of the performance toa given requirement.

A control panel on the motor terminal box enables setting of required setpoint as well as setting ofpump to "Min." or "Max." operation or to "Stop". The Grundfos Eye indicator on the control panelprovides visual indication of pump status:

- "Power on": Motor is running (rotating green indicator lights) or not running (permanently greenindicator lights)

- "Warning": Motor is still running (rotating yellow indicator lights) or has stopped (permanentlyyellow indicator lights)

- "Alarm": Motor has stopped (flashing red indicator lights).

Communication with the pump is possible by means of the Grundfos GO Remote (accessory). Theremote control enables further settings as well as reading out of a number of parameters such as"Actual value", "Speed", "Power input" and total "Power consumption".

The terminal box holds terminals for these connections:- one dedicated digital input- two analog inputs, 0(4)-20 mA, 0-5 V, 0-10 V, 0.5 - 3.5 V- 5 V voltage supply to potentiometer and sensor- one configurable digital input or open-collector output- Grundfos Digital Sensor input and output- 24 V voltage supply for sensors- two signal relay outputs (potential-free contacts)- GENIbus connection- interface for Grundfos CIM fieldbus module.

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.

Frequency converter operation offers these functions:- controlled operation, i.e. consumption flucturates- constant pressure- communication with the pump.

Adaption of performance through frequency-controlled speed offers obvious benefits such as:- energy savings- increased comfort

Position Qty. Description- control and monitoring of the application and pump performance.

A control panel on the motor terminal box enables setting of required setpoint as well as setting ofpump to "Min." or "Max." operation or to "Stop". The Grundfos Eye indicator on the control panelprovides visual indication of pump status:

- "Power on": Motor is running (rotating green indicator lights) or not running (permanently greenindicator lights)

- "Warning": Motor is still running (rotating yellow indicator lights) or has stopped (permanentlyyellow indicator lights)

- "Alarm": Motor has stopped (flashing red indicator lights).

Communication with the pump is possible by means of the Grundfos GO Remote (accessory). Theremote control enables further settings as well as reading out of a number of parameters such as"Actual value", "Speed", "Power input" and total "Power consumption".

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 IE5 in accordance with IEC 60034-30-2.The motor requires no external motor protection. The motor control unit incorporates protection againstslow- and quick-rising temperatures, e.g. constant overload and stalled conditions.

The terminal box holds terminals for these connections:- one dedicated digital input- two analog inputs, 0(4)-20 mA, 0-5 V, 0-10 V, 0.5 - 3.5 V- 5 V voltage supply to potentiometer and sensor- one configurable digital input or open-collector output- Grundfos Digital Sensor input and output- 24 V voltage supply for sensors- two signal relay outputs (potential-free contacts)- GENIbus connection- interface for Grundfos CIM fieldbus module.
