Vertical, multistage centrifugal pump with suction and discharge ports on the same level. The pump head and base are in cast iron – all other wetted parts are in stainless steel (EN 1.4301)
Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). 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 access and service. Power transmission is via a rigid split coupling. Pipe connection is via
combined DIN-JIS flanges.
The pump is fitted with a 3-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 vent screw.
The pump is fitted with a balanced O-ring seal unit with a 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.
Seal faces:
• 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 surfaces, and the shape of the blades
ensure a high efficiency.
The base is made of cast iron. The flanges and base are cast in one piece. The outlet side of the base has a drain
plug. 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 efficiency is classified as IE3 in accordance with IEC 60034-30-1.
The motor has thermistors (PTC sensors) in the windings in accordance with DIN 44081/DIN 44082. The protection
reacts to both slow- and quick-rising temperatures, e.g. constant overload and stalled conditions.
Thermal switches must be connected to an external control circuit in a way which ensures that the automatic reset
cannot cause accidents. The motors must be connected to a motor-protective circuit breaker according to local
regulations.
The motor can be connected to a variable speed drive for adjustment of pump performance to any duty point.
