Vertical, multistage centrifugal pump
with suction and discharge ports on the same level.
Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). Pump materials in contact
with the liquid are in high-grade 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 DIN flanges.
Further product details
An external sensor can be connected if controlled pump operation based on for example flow, differential pressure or
temperature is required.
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
The motor stool connects the pump head and motor. 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 retained in the pump head by a cover and screws. It can be replaced without removing the motor.
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 pump has a stainless-steel base mounted on a separate base plate.
The base and base plate are kept in position by the tension of the staybolts which hold the pump together.
Both the inlet and the outlet side of the base have two pressure gauge tappings.
The pump is secured to the foundation by four bolts through the base plate.
The flanges are fastened to the base by means of locking rings.
Motor
The motor is a totally enclosed, fan-cooled motor with principal dimensions to IEC and DIN standards. Electrical
tolerances comply with IEC 60034.
