Product No.: 96496701

Vertical, multistage centrifugal pump with suction and discharge ports on same the level (in-line)enabling installation in a horizontal one-pipe system. Pump materials in contact with the liquid are inhigh-grade stainless steel. A cartridge shaft seal ensures high reliability, safe handling and easyservice and access. Power transmission is via a split coupling. Pipework connection is via PJE(Victaulic®) couplings.

The pump is fitted with a 1-phase, fan-cooled asynchronous motor.

Further product detailsSteel, 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 and flange for motor mounting is made in one piece (cast iron). The pump headcover is a separate component (stainless steel). The pump head has a combined 1/2" priming plugand air vent screw.

Position Qty. DescriptionThe 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 pump has a stainless steel base mounted on a separate base plate. The base and base plateare kept in position by the tension of the staybolts which hold the pump together. The discharge sideof the base has a combined drain plug and bypass valve. The pump is secured to the foundation byfour bolts through the base plate. The base is prepared for connection by means of PJE (Victualic®)couplings.

MotorThe motor is a totally enclosed, fan-cooled motor with principal dimensions to IEC and DINstandards. 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 has built-in thermal protection (PTO current and temperature sensors) in accordance withIEC 60034-11 and requires no further motor protection. The protection reacts to both slow- andquick-rising temperatures, e.g. constant overload and stalled conditions.As the thermal protection incorporates automatic reset, the motor must be connected in a way whichensures that the automatic reset cannot cause accidents.
