In order for standard centrifugal pumps to, the casing has to be filled with liquid before start-up and have a positive suction head to operate efficiently. The NPSHr (Net Positive Suction Head Required) can be provided during the selection and assessment of the pump for your intended application.
Upon start-up, the liquid enters the centrifugal pump casing axially onto the eye of the impeller. The rotating impeller generates a centrifugal force accelerating the liquid through the pump casing and into the discharge piping. As the fluid is accelerated by the impeller and thrown towards the discharge outlet a low-pressure point is generated at the eye of the impeller effectively drawing fluid from the suction side to the pump and continuing the pumping cycle.
The CTH units are fitted with Safe Area IP55 Motors in Aluminium Casings as standard and are in line with all current Energy Efficiency Class legislation.

[/tm_tab] [tm_tab title="OPERATING PRINCIPLE"]
Operating Principle of CTM Centrifugal PumpsIn order to start the pump, the casing has to be filled with liquid before start-up and have a positive suction head to operate efficiently. The NPSHr (Net Positive Suction Head Required) can be provided during the selection and assessment of the pump for your intended application. Upon start-up, the liquid enters the pump casing axially onto the eye of the impeller. The rotating impeller generates a centrifugal force accelerating the liquid through the pump casing and into the discharge piping. As the fluid is accelerated by the impeller and thrown towards the discharge outlet a low pressure point is generated at the eye of the impeller effectively drawing fluid from the suction side to the pump and continuing the pumping cycle. Unlike standard close coupled centrifugal pumps where the impeller is connected to the motor shaft directly, in a CTM Magnetically Driven Centrifugal Pump, the torque from the motor shaft is transmitted to the impeller by means of a magnetic coupling. The drive magnet is fixed on the motor shaft. The magnets installed in the drive magnet and in the impeller/magnet assemblies have different polarities. When the pump is at rest, the magnets of both parts are aligned. When the motor is started and the drive magnet starts to rotate, the magnets create an attraction and repulsion force thus forcing the impeller to rotate. If the impeller gets blocked or the pumped liquid will be too dense and too much torque will be generated on the motor shaft, the magnet will de-couple and no damaged will be done to the motor. When the pump will come to a stop, the magnets will re-couple. Between both magnet assemblies there is an isolation shell that separates the liquid side from the motor side and from entering the atmosphere. [/tm_tab] [tm_tab title="APPLICATIONS"]

CTV Vertical Immersion Centrifugal Pumps (2)[tm_tabs style="5"] [tm_tab title="PRODUCTS"] [/tm_tab] [tm_tab title="INTRODUCTION"]
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. [/tm_tab] [tm_tab title="APPLICATIONS"]
Typical ApplicationsThe CTV Range is commonly used in a variety of immersion applications, for example:

Sealing OptionsStandard Single Mechanical Seals are provided with a range of face materials, Ceramic / Graphite / SiC and O-Rings are available in EPDM / FKM / FFKM or FEP or alternatively the seal can be provided with an OP-Ring (Square O-Ring). This increases the friction between the O-Ring and the back casing and therefore lowering the chances of the static parts of the seal from sticking together. Lubricated & Externally Quenched Mechanical Seals can also be provided upon request and are ideally used when there is the potential for dry running or where there is a chance for the product to solidify or crystalize. An Oil Pot is connected to the seal chamber and continually lubricates seal during operation. SAE grade 20 Oil is recommended however you must use a fluid compatible with the pumped medium and materials within the pump. As an alternative, the CTHs can be supplied with ports to facilitate an external quench system. This provides the added benefit of removing heat build-up from the seal face and doesn’t require changing of the lubricating fluid. The max pressure of the quench circuit is 0.5 bar and it is recommended to install a thermo-syphon circulation into the quench circuit. [/tm_tab] [/tm_tabs]
