CR 3-8 A-A-A-E-HQQE
Note! Product picture may differ from actual product
Product No.: 96511543
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 – all
other wetted parts are in stainless steel. A cartridge shaft seal ensures high reliability, safe handling
and easy service and access. Power transmission is via a split coupling. Pipework connection is via
oval flanges with internal Rp threads.
The pump is fitted with a 1-phase, fan-cooled asynchronous motor.
Further product details
Steel, cast iron and aluminium components 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 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.
Pump
A standard split coupling connects the pump and motor shaft. It is enclosed in the pump head/motor
stool 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 a combined 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 seal type 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 the pump 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
this 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 a
PTFE 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 the
base has a combined drain plug and bypass valve. The pump is secured to the foundation by four
bolts through the base plate.
Motor
The 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 has built-in thermal protection (PTO current and temperature sensors) in accordance with
IEC 60034-11 and requires no further motor protection. The protection reacts to both slow- and
quick-rising temperatures, e.g. constant overload and stalled conditions.
As the thermal protection incorporates automatic reset, the motor must be connected in a way which
ensures that the automatic reset cannot cause accidents.
