Tapflo CTV

Tapflo Vertical Pumps

CTV is a single stage vertical centrifugal pump that is simple but very reliable in duty. The pump is specialized for transfer and circulation of various liquids from containers, sumps and tanks. 

How they work

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. Further on the pump is designed to be dry running safe.

The simple design without bearings or mechanical seals grants for a pump that is usually maintenance free. CTV is also insensitive of solids, up to ?? mm are allowed (depending of pump size).

In many installations the CTV pump replaces a self priming pump. The pump head of the CTV is submersed in the liquid. The pump operates more reliable compared with a self priming pump. The submersion depth is 419-425 mm (depending on model) but may also be equipped with a suction extension.


CTV is manufactured from PP (polypropylene), PVDF or stainless steel AISI 316L.

PP (polypropylene) is suitable for most type of chemicals at temperatures up to 70°C. Ideal for pickling baths and acid degrease solutions etc.

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 in special applications like hot sodium hydroxide.

All wetted metal components are made from corrosion resistant stainless steel AISI 316L.

For special applications like handling of chromium nickel, electro polished models are available.

Typical applications
