Product No.: On request

Non-self-priming, single-stage, centrifugal volute pump designed according to ISO 5199 withdimensions and rated performance according to EN 733 (10 bar). Flanges are PN 16 with dimensionsaccording to EN 1092-2. The pump has an axial suction port, radial discharge port, horizontal shaft anda back pull-out design enabling removal of the motor, motor stool, cover and impeller without disturbingthe pump housing or pipework.

The unbalanced rubber bellows seal is according to DIN EN 12756.The pump is close-coupled to a fan-cooled, permanent-magnet synchronous motor.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.

Further product detailsThe product's minimum efficiency index (MEI) is greater or equal to 0.70. This is by the CommissionRegulation (EU) considered as an indicative benchmark for best-performing water pump available onthe market as from 1 January 2013.

An external sensor can be connected if controlled pump operation is required for flow, differentialpressure or temperature control.An operating 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 operating 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 Grundfos GO Remote (accessory). The remotecontrol enables further settings as well as reading out of a number of parameters such as "Actualvalue", "Speed", "Power input" and total "Power consumption".

The back pull-out design means that the pump can be serviced by a single person without disturbingthe pump housing or pipe work.

Cast-iron parts have an epoxy-based coating made in a cathodic electro-deposition (CED) process.CED is a high-quality dip-painting process where an electrical field around the products ensuresdeposition of paint particles as a thin, well-controlled layer on the surface. An integral part of theprocess is a pretreatment. The entire process consists of these elements:1) Alkaline-based cleaning.2) Zinc phosphating.3) Cathodic electro-deposition.4) Curing to a dry film thickness 18-22 my m.The colour code for the finished product is NCS 9000/RAL 9005.

Pump

Position Qty. DescriptionThe pump housing has both a priming and a drain hole closed by plugs.The impeller is a closed impeller with double-curved blades with smooth surfaces. The impeller isstatically balanced according to ISO 1940-1 class G6.3 and hydraulically balanced to compensate foraxial thrust.Wear rings used in pump housing and for impeller are made of bronze/brass or cast iron.

Motor stool and pump cover are made of cast iron (EN-GJL-250). Coupling guards are fitted to themotor stool. The pump cover is provided with a manual air vent screw for venting of the pump housingand the shaft seal chamber.

The pump is fitted with an unbalanced rubber bellows seal with torque transmission across the springand around the bellows. Due to the bellows, the seal does not wear the shaft, and the axial movementis not prevented by deposits on the shaft.Primary seal:

• Rotating seal ring material: carbon graphite, metal-impregnated• Stationary seat material: silicon carbide (SiC)

This material pairing has a very good corrosion resistance and is especially suitable for water up to 120°C. However, seal life will be reduced at temperatures above 90 °C. The material pairing is notrecommended for liquids containing particles as this will result in heavy wear on the SiC face.Secondary seal material: EPDM (ethylene-propylene rubber)EPDM has excellent resistance to hot water. EPDM is not suitable for mineral oils.

MotorThe motor is a totally enclosed, fan-cooled motor with principal dimensions to IEC and DIN standards.Electrical tolerances comply with IEC 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.
