Overview
CTV is a single stage vertical centrifugal pump that is simple but very reliable in duty.
It is manufactured from:
- plastic (PP or PVDF)
- stainless steel (AISI 316L).
The pump is specialized for transfer and circulation of various liquids from containers, sumps and tanks.
Features & benefits
Leakage free and dry running safe
CTV is installed vertically with the motor above the liquid surface. In this way the pump does not need any mechanical seal that usually is a source for leakage problems. Furthermore the pump is designed to be dry running safe.
Replacing self priming pumps
In many installations the CTV pump replaces a self-priming pump. The CTV pump head is submersed in the liquid. The pump operates more reliably compared to a self-priming pump. The submersion depth is up to 425 mm (depending on model), but may also be equipped with a suction extension.
Maintenance free
The simple design without bearings or mechanical seals grants for a pump that is usually maintenance free. CTV is also insensitive of solids, particles up to Ø 6 mm are allowed.

Certificates
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).
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.
Key components
PP
PP (polypropylene) is suitable for variety of chemicals at temperatures up to 70°C. Ideal for pickling baths and acidic degreasing solutions.
PVDF
PVDF (polyvinylidene fluoride) has superior chemical and mechanical features. Ideal with hot acids up to 100°C, for example hot hydrofluoric acid.
Stainless steel pumps
The stainless steel version is ideal at higher temperatures, up to 100°C and for special applications like transfer hot sodium hydroxide. All wetted metal components are made of corrosion resistant stainless steel AISI 316L.
