Horizontal radially split volute casing pump in back pull-out design, with radial impeller, single-entry, single-stage, to ISO 2858 / ISO 5199. Also available as a variant with “wet” shaft, conical seal chamber and/or semi-open impeller (CPKNO). ATEX-compliant version available.
Application pump cpkn
Pumping aggressive liquids in the chemical and petrochemical industries, refinery systems, fire-fighting systems and for brine transport.
Fields of Application cpkn
For handling aggressive organic and inorganic fluids in the chemical and petrochemical industries.
They are also used in:
refinery off-sites, the paper and cellulose industries, the foodstuffs industry, the sugar industry, sea water desalination plants, absorption equipment in environmental engineering, power stations, etc.
Desing Details pump cpkn ksb
Radially split, consisting of volute casing (on CPKN-S with casing wear ring) and casing cover.
Double volute depending on pump size.
The casing cover and the bearing bracket lantern form a chamber which can be used for heating or cooling with superheated steam or water, respectively (except for pump design with conical seal chamber).
Axial thrust is balanced by back vanes, for impeller diameters
> 500 with sealing clearance on both sides.
The shaft seal can be designed as a gland packing or a mechanical seal.
Conversion from gland packing to single-acting mechanical seal and vice versa is possiblewithout any rework on the casing cover by using the relevant replacement parts.
The pumps use proprietary single or double seals. Preference is given to standardised mechanical seals of various makes to EN 12756 (type of construction L1K).
Single-acting mechanical seals can be fed with quenching media. A throttling bush, shaft seal ring or secondary mechanical seal can be fitted as outboard seal.
