PT High pressure hose pumps
The Tapflo Hose Pump range is a series of pumps for industrial and hygienic applications. The pumps are designed to be safe, simple and easy to use and maintain. The pumps are suitable for almost all different liquids used by the industry today. The pumps are powered with an electric motor which is coupled with the rotor. To decrease the motor rotational speed a gearbox is used.
The Tapflo hose pump is driven by a gear-motor. The rotor is installed directly on the shaft. It is equipped with shoes or has a special shape itself. The shoes compress the hose creating vacuum on the suction side of the pump and pressure on the discharge to transfer the liquid.
Typical applications: industrial, paint, waste water treatment, food, paper mills, chemical, biogas, recycling, mining, building

The pump generates friction and heat, while compressing the hose, therefore constant lubrication with glycerin is needed to dissipate the heat. This design allows the pump to operate within higher discharge pressure up to 15 bar, avoiding any blockage and optimising therefore the lifetime of the hose.
The Tapflo hose pump is driven by a gear-motor. The rotor is installed directly on the shaft. It is equipped with shoes or has a special shape itself. The shoes compress the hose creating vacuum on the suction side of the pump and pressure on the discharge to transfer the liquid. The rotary movement of the shoes compresses the hose along the casing wall, constantly sucking/pushing the liquid through the hose. Flow is reversible as pumping direction depends on motor rotation. Pump casing is filled with lubricant to reduce the friction between the hose and the shoes. The hose and the pump inserts (connections) are the only parts of the pump that are in contact with the pumped liquid.

Features & Benefits
At Tapflo we have focused on reducing hose wear, and our dedicated engineers are fully immersed in this important mission.
As a result, our newly upgraded Tapflo hoses outperform the competition, lasting approximately 30% longer than any other hoses in the market.
New Tapflo hoses are characterized by a non- machined external surface, which revolutionizes the lubrication of our reinforced hoses. This feature ensures a superior grip for the lubricant, reducing friction and significantly lowering heat generation.

The outcome? An unprecedented extension in hose lifetime that sets our products apart.
Less friction and lower heat build-up between the shoes and the hose.
Hose pump can pump abrasive, corrosive, aggressive liquids with particles.
To optimise the lifetime of the hose you need to enhance varoius factors that act together:
These parameters combined with a precise tolerance lead to a better hose lifetime of 30% then other hoses on the market.
Certificates may vary depending on the material execution of a particular product.

The use of pulsation dampers in the discharge line guarantees a number of advantages, such as: significant reduction of discharge pulsations, vibrations and noise. This solution protects not only the pump, but also the piping and instrumentation.
The rupture of the hose, which is a wear part, creates a leakage of the pumped liquid. As a result, the level of the medium in the pump casing rises and is detected by a capacitive sensor, which immediately stops the pump.
Built-in frequency inverters are a solution for comfortable pump speed control. Allows easier exchange of the hose. The unit is equipped with a IP66 programmed frequency inverter and all necessary equipment such as wires and plugs.
The main advantage of this solution is that the inverter is mounted directly on the pump, which makes the whole unit compact and ready to use.
Trolleys are designed to enable mobility and ease of use, while maintaining proper pump stability. Thanks to these new accessories, pumps can be easily transported and the most important, used in many applications and locations.
The revolution counter allows to monitor the number of rotor revolutions. This accessory can be equipped with a control cabinet. Based on the volume per revolution data, this allows to calculate and batch products according to customer needs.
Revolution counter can be also equipped with external digital display for easy monitoring of the pump speed and capacity.
The vacuum system is utilized in applications where viscous products are handled (above 10 000 cP) or with a negative suction lift. Because of the liquid viscosity the hose does not return to initial shape fast enough and the capacity decreases.
By installing a vacuum system, efficiency drops are eliminated, as the pressure inside the pump is reduced and the hose is expanding quicker.
