Note! Product picture may differ from actual product
Product No.: On request
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.
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.
