CTH hygienic Pumps

Overview

The CTH series is dedicated for hygienic duties mainly within food, beverage and pharmaceutical industries. With casing and impeller in <0.8 Ra electro polished stainless steel AISI 316L, draining possibilites and hygienic shroud option it meets the demands of clean ability and high finish. Elastomers are approved according to FDA article177.2600.

Various sealing materials

Standard single mechanical seal provides a wide range of seal face materials – ceramic, graphite, SiC and o-rings in FDA approved EPDM or FEP.

Insensitive for solids

The open impeller is insensitive for solids (max 6 mm). Semi open impeller for heavy duty applications is available as option.

Hygienic connections

Hygienic connections DIN 11851 (thread) are standard on the CTH series. It is also available with clamp connections (DIN or ISO), SMS or RJT threads.

Heating jacket

Great protection for the mechanical seal in cases where there
is a risk for solidification of the product. The heating jacket is
also used when the pumped product has to maintain a specific temperature, high or low.
A heating or cooling medium is continuously circulated in the jacket.
Chocolate glaze, paraffin, starch, glucose syrup, margarine and
eatable oil are some application examples.

Certificates

USP logo vertical RGB

USP VI approved materials (OPTION)

U.S. Pharmacopeial Convention (USP) class I to VI defines how a plastic or rubber material may be exposed of human tissue. Class VI requires the most stringent testing and such materials may be used for example in implant devices.

fda

FDA §21 CFR 177 materials

FDA (U.S. Food and Drug Administration) §21 CFR 177 lists polymers, e.g. rubber and plastic materials approved for equipment in contact with food products.

EN 10204

EN 10204 material traceability

The EN 10204 norm gives you a checklist and traceability of materials used in the equipment. 2.1 is a general statement of compliance with material specifications, while 3.1 provides specific track records all the way to the steel mill batch (normally only on metals in contact with the product).

EC 1935/2004 regulation

This EU regulation applies to all food contact materials, e.g. metals, plastics and rubber materials. It requires that these materials are safe, are labeled with the glass-and-fork symbol, are traceable throughout the production chain (according to above EN 10204) and that they are produced according to good manufacturing practice (GMP).

CE conformance

A product classified as machinery that carries the CE mark fulfill the essential health and safety requirements of the EC Machinery Directive 2006/42/EEC.
