CTN

Product catalog summary

Product Introduction
The document introduces the CTN series of chemical shaft-driven sump pumps, designed for handling chemically aggressive liquids, including those slightly contaminated or with low solids content. The CTN-H variant is suitable for liquids that require warm or hot conditions for pumping.

Fields of Application
These pumps are applicable in the chemical and petrochemical industries.

Design Specifications
The CTN pumps are vertical, radially split shaft-driven sump pumps with a double volute casing. They can be installed in wet or dry conditions and feature a radial impeller, available in single-flow, single- and double-stage configurations. The shaft seal is designed to avoid contact with the pumped product.

Operating Data

Capacities: Up to 220 l/s (800 m3/h)
Heads: Up to 93 m
Pump sizes: DN 25 to 250
Operating pressures: Up to 16 bar
Operating temperatures: -70°C to +300°C

Certification
The pumps are certified under ISO 9001 quality management standards.

Materials
The document lists materials used for various components of the CTN and CTN-H pumps, including options for different material variants depending on the pumped liquid.

Design Features

Thrust bearing with minimal axial movement, adjustable rotor.
Discharge pipe designed for easy installation.
Pressure-retaining components manufactured with corrosion allowance.
Shaft seal options include gland packing or mechanical seal.
Interchangeable soleplate design for certain pump sizes.
Modular design allows variable installation depth.
Product-lubricated plain bearings.
Replaceable casing wear rings.
Double volute design reduces load on bearings.
