Design cpkn-sx
Horizontal, long-coupled, single-stage volute casing pump in back pull-out design. Replaceable shaft protecting sleeves and casing wear rings.
Application pump cpkn-sx
Sprinkler systems to VdS and fire protection.
Casing pump cpkn-sx
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).
Desing Details pump cpkn-sx
Shaft Seal
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.
