Product No.: On request
Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). The pumphead and base are in cast iron – all other wetted parts are in stainless steel. A cartridge shaft sealensures high reliability, safe handling, and easy access and service. Power transmission is via a rigidsplit coupling. Pipe connection is via oval flanges with internal Rp threads.
The pump is fitted with a 1-phase, fan-cooled, permanent-magnet, synchronous motor.The motor efficiency 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. An operating panel on the motor terminal box enables setting of required setpointas well as setting of pump to "Min." or "Max." operation or to "Stop". The Grundfos Eye indicator on theoperating panel provides 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 terminal box has a number of inputs and outputs enabling the motor to be used in advancedapplications where many inputs and outputs are required:
• two dedicated digital inputs• three 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 analog output, 0-10 V, 0(4)-20 mA• two configurable digital inputs or open-collector outputs• two Pt100/Pt1000 inputs• LiqTec, dry-running protection sensor input• 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 detailsAn external sensor can be connected if controlled pump operation based on for example flow,differential pressure or temperature is required.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).

Position Qty. DescriptionSteel, cast iron and aluminium components have an epoxy-based coating made in a cathodicelectro-deposition (CED) process. CED is a high-quality dip-painting process where an electrical fieldaround the products ensures deposition of paint particles as a thin, well-controlled layer on the surface.An integral part of the process 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.
PumpA standard split coupling connects the pump and motor shaft. It is enclosed in the pump head/motorstool by means of two coupling guards.
The pump head, pump head cover and flange for motor mounting is made in one piece. The pumphead has a combined 1/2" priming plug and vent screw.
The pump is fitted with a balanced O-ring seal unit with a rigid torque-transmission system. This sealtype is assembled in a cartridge unit which makes replacement safe and easy. Due to the balancing,this seal type is suitable for high-pressure applications. The cartridge construction also protects thepump shaft from possible wear from a dynamic O-ring between pump shaft and shaft seal.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 shaft seal is screwed into the pump head.
The chambers and impellers are made of stainless-steel sheet. The chambers are provided with aPTFE neck ring offering improved sealing and high efficiency. The impellers have smooth surfaces, andthe shape of the blades ensure a high efficiency.
The base is made of cast iron. The oval flanges are bolted to the base. The outlet side of the base hasa combined drain plug and bypass valve. The pump is secured to the foundation by four bolts throughthe base plate.

MotorThe motor is a totally enclosed, fan-cooled motor with principal dimensions to IEC and DIN standards.The motor is flange-mounted with tapped-hole flange (FT).Motor-mounting designation in accordance with IEC 60034-7: IM B 14 (Code I) / IM 3601 (Code II).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 has a number of inputs and outputs enabling the motor to be used in advancedapplications where many inputs and outputs are required:
• two dedicated digital inputs• three 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 analog output, 0-10 V, 0(4)-20 mA• two configurable digital inputs or open-collector outputs• two Pt100/Pt1000 inputs• LiqTec, dry-running protection sensor input• 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.
