Overview
The CT pumps are open or semi open impeller single stage centrifugal pumps. They are manufactured in high finish and mechanically strong material - AISI 316L stainless steel. The pump range meets the demands from a variety of today’s industries. Having said that, CT is still available at a very appealing price level.
The hygienic series CTH is supplied with electro polished pump casing and internals. This series is dedicated for hygienic duties in food, beverage and pharmaceutical industries, where clean and drain-ability are important factors.
Standard single mechanical seal provides a wide range of seal face materials - ceramic, graphite, SiC and EPDM, FKM, NBR, FEP O-rings compliant with FDA and EC1935 requirements
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.

The open impeller is able to handle solids up to 6 mm. Semi open impeller for heavy duty applications is available as an option.

Options
Options and special executions
Hygienic shroud
The hygienic motor shroud in polished AISI 316L protects the motor from spraying water during pump cleaning procedure.
Buffer fluid system
A great option when the product tends to solidify or crystalize. A lube reservoir is connected to the air side of the mechanical seal.
Long coupled execution
The perfect solution when pumping hot products like oil at temperatures up to 180°C. Complete pump unit mounted on baseplate, with coupling and cover.
Casing drainage
Plug at the bottom of the pump casing allows draining of the pumped liquid.
Heating jacket
Great protection for the mechanical seal in cases where there is a risk for solidifying 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.

Certificates
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 §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 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.
ATEX Directive 94/9/EC
Equipment intended and approved for safe operation in potentially explosive atmospheres. The equipment is divided in main groups, categories, apparatus groups and temperature classes to define its suitability in the actual zone.
Key components
Impeller types
Semi-open impeller
Slightly contaminated liquids or non-aggressive wastewater. Efficiency almost as good as closed impeller.
Open impeller
Possibility of pumping contaminated liquids without adversely affecting pump operation.
Big choice of sealing solutions
The CTI & CTH pump range features top brand mechanical seals in a variety of materials to suit most type of liquids. They are available in combinations of ceramic, graphite and SiC. For special duties, flushed and lubricated seals are available.
