Product No.: 96512510

Vertical, multistage centrifugal pump with suction and discharge ports on same the level (in-line)enabling installation in a horizontal one-pipe system. The pump head and base are in cast iron – allother wetted parts are in stainless steel. A cartridge shaft seal ensures high reliability, safe handlingand easy service and access. Power transmission is via a split coupling. Pipework connection is viaoval flanges with internal Rp threads.

The pump is fitted with a 1-phase, fan-cooled asynchronous 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 theperformance to a given requirement.

Further product detailsAn external sensor can be connected if controlled pump operation based on for example flow,differential pressure or temperature is required.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 control panel has indicator lights for "Operation"and "Fault".

Communication with the pump is possible by means of the Grundfos GO Remote or the R100remote control (accessories). The remote controls enable further settings as well as reading out of anumber of parameters such as "Actual value", "Speed", "Power input" and total "Powerconsumption".

Steel, 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 electricalfield around the products ensures deposition of paint particles as a thin, well-controlled layer on thesurface. An integral part of the process is a pretreatment. The entire process consists of theseelements:

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 pump head has acombined 1/2" priming plug and air vent screw.

The pump is fitted with a balanced O-ring seal unit with 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 ofthis material 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 surface,and the shape of the blades ensure a high efficiency.

The base is made of cast iron. The oval flanges are bolted to the base. The discharge side of thebase has a drain plug. The pump is secured to the foundation by four bolts through the base plate.

Motor

2/8



The motor is a totally enclosed, fan-cooled motor with principal dimensions to IEC and DIN standards. The motoris 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 requires no external motor protection. The motor control unit incorporates protectionagainst slow- and quick-rising temperatures, e.g. constant overload and stalled conditions.

The terminal box holds terminals for these connections:- pump start/stop input (potential-free contact)- remote setpoint setting via analog signal, 0-10 V, 0(4)-20 mA- 10 V voltage supply for setpoint potentiometer, Imax = 5 mA- one analog sensor input, 0-10 V, 0(4)-20 mA- 24 V voltage supply for sensor, Imax = 40 mA- one analog output- three digital inputs- one potential-free fault signal relay with changeover contact, reporting "Fault", "Operation" or

"Ready"- RS-485 GENIbus connection.
