  1. Tapflo CTM magnetic drive pumps

    Type: CTM pumps 

    Description: CTM pumps are used in most industries where liquids are pumped. The pumps handle many types of low and normal viscous clean liquids such as chemical aggressive and toxic.

    How they work: The power from the motor is transmitted to the centrifugal impeller by means of a magnetic coupling. A so called isolation shell between the drive magnet and the impeller magnet separate the liquid side from the drive.

    Flushed seal, Ideal when abrasive or sticky particles are present. This system where a small amount of the pumped product is recirculated from the discharge side to the seal chamber, will save the mechanical seal and seal chamber from being worn

    Features & Benefits:

    Made from stainless steel- Strong and durable

    Open impeller- Can handle solids up to 6 mm

    Few components- Easy to maintain

    Closed coupled motor- Compact and space saving

  4. Tapflo Diaphragm Pumps PE & PTFE Series

    Type: Air Operated Diaphragm Pumps

    Description: PE & PTFE series pumps

    Tapflo pumps made from polyethylene (PE) or virgin PTFE plastics are suitable for handling almost any kind of liquid whether it is viscous, chemically aggressive or with solids.

    Few components and a simple but ingenious design is peculiar for all Tapflo pumps. It is a compact pump, easy and quick to maintain, keeping your service costs and process down time to a minimum.

    Polyethylene (PE HD) has a superior wear resistance which is 6 – 7 times better than for polypropylene (PP). This fact makes the pump suitable for handling abrasive slurries etc. PE is resistant to most kind of aggressive chemicals such as concentrated acids and alkalis. Maximum liquid temperature is 70°C.

    PTFE (virgin polytetrafluorethylene) is a thermoplastic polymer with superior chemical resistance. The PTFE pump will handle even the most aggressive acids, for instance concentrated nitric acid. Maximum liquid temperature is up to 100°C.


    Chemical: Acids, alkalis, alcohol, solvents, latex, emulsions
    Food: CIP fluid, flavouring, pigments
    Pulp & Paper: Glue, slurries, adhesives, dispersions, resins, sodium silicate, titanium oxide

  6. Tapflo Vertical Pumps CTV

    Type: Tapflo Vertical Pumps

    Description: 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.

    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.

    Materials:  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 are 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

    Industry   Example of application
