What do make CTV Vertical Immersion Centrifugal Pumps different?

The CTV Vertical Immersion Centrifugal Pump is simple however very reliable in service. The pump has been specialised for the transfer and circulation of various fluids from containers, tanks and sumps. They are manufactured from PP, PVDF or Stainless steel AISI 316L.

In many cases the CTV replaces a self-priming pump as it is installed vertically with the motor above the liquid surface. This means that the pump doesn’t need a mechanical seal that usually is a source for leakage problems. Furthermore, the pump is designed to be safe from dry running.

The simple design without bearings or mechanical seals grants for a pump that is usually maintenance free. It is also insensitive of solids up to 6 mm in diameter (depending on the pump size).

The submersion depth of the CTV series varies from 419-425 mm (depending on model) but may also be equipped with a suction extension.

Typical Applications

The CTV Range is commonly used in a variety of immersion applications, for example:

Surface Treatment Transfer and Return pumping in galvanizing, hot zinc, pickling & oxidisation processes.
Water Treatment Transfer and Return Pumping of dirty and contaminated water
Heat Exchangers Return Pumping
Waste Disposal Emptying of dirty drains and sumps

CTV typical applicationCTV Vertical Immersion Centrifugal Pumps can also be commonly used in conjunction with our FT Filter units to complete a transfer & purification cycle of waste products within the aforementioned applications.

CTV Vertical Immersion Centrifugal Pumps Motor Options

The CTV units are fitted with a Safe Area IP55 Motors in Aluminium Casings as standard and are in line with all current Energy Efficiency Class legislation. Motor Powers vary from 0.55 kW up to 2.2 kW in 2 Pole 50 Hz and Single or 3 Phase. S1 Duty Class is standard. Tropicalised motors to IP55 or 56 are available as options

Hygienic Motor shrouds and Rain / Top Hats are available to protect motors in wash down or external operating conditions. External cooling options for variable speed operation are also available upon request.

Other Configurations & Options for CTV Vertical Immersion Centrifugal Pumps

Baseplates: Hendor & Babco styles are available on request as well as smaller sizes to allow for smaller sump and tank openings.

Bigger openings are also available for easily drying liquids.

FDA Compliant Wet Side Elastomers are also available when the pump is being used in hygienic applications.

 CTV Connection Options – 5A & 5D  Connection Options – 5A & 5D

BSP (Standard)

Flanged to DIN / ANSI 150 or EN 1092–1 Type B (Loose or one piece welded)

CAM Lock Male

 CTV Suction Extension & Strainer Options – 4E05, 4E10 & 4S  Suction Extension & Strainer Options – 4E05, 4E10 & 4S

The pump can be delivered with a suction extension pipe. It is a great solution when there is a need to empty a tank or sump from a lower level than the immersion depth of the pump.

A 500 mm and 1000 mm extension pipe is available as a standard. Customised lengths are available on request.

It is recommended to fasten long suction pipes to the wall of the tank. The supports need to be flexible and should not cause any vibration to the piping.

 A suction strainer is also a possible option where the liquid is dirty or contains solids larger than the capacity of the pump (up to 6 mm ø).

These are available in PP, PVDF and SS 316L

  As standard the pump cover is cut with a socket, however in applications where the liquid is particularly viscous a left handed thread on the cover can be provided to avoid unscrewing of the pump cover during operation.
 CTV Motor Mounting Screw Protecting Plugs Option – 8P  Motor Mounting Screw Protecting Plugs Option – 8P

In situations when there is a risk of liquid evaporation and damaging the motor mounting screws, protection plugs are available to ensure that no vapours will reach them.
