Hygienic diaphragm pump T825 ST

To fulfill the process requirements, Tapflo proposed a hygienic air-operated diaphragm pump T825 ST equipped with flap valve design that enables gentle handling of large, soft solids compared to standard ball valve configurations. The low-shear pumping principle of diaphragm pumps helps preserve the structure of delicate solids such as mushrooms.

The hygienic design with smooth product-contact surfaces facilitates cleaning and reduces product residues.Tapflo flap valves provide improved hygienic features compared to traditional flap valve designs. They offer a good balance between solids handling, performance and hygiene.

The largest T825 air-operated hygienic pump, equipped with flap valves, allows pumping particles up to approximately 100 mm, depending on their shape and hardness. As a standard, the T825 pump is a 3” pump but when utilizing flap valves the pumps internal clearances are critical therefore the pump size was increase to 4” in the flap valve design.

RESULT

The solution was tested at the customer’s site under real operating conditions. The results confirmed that 95% of the mushrooms remain undamaged after passing through the pump. The pump’s performance is excellent for mushrooms with a diameter of approximately 70-80 mm as well as smaller ones. Smaller particles generally allow for more stable and efficient pump operation.

Due to changes in the way we think about our impact on the environment, we are proud to present EODD – Electric Diaphragm Pumps. The product follows a modern approach but is still based on the original diaphragm pump technology, which has proven to be very effective. We consulted with our customers, who expressed a need for the features and benefits of a traditional diaphragm pump, but with the added advantage of lower operating costs. The pump is powered by a high-efficiency electric motor (IE3 class) and there is no chance of hydraulic fluid leakage, as the pump simply does not need it.

A Filter Press Pump is a specialized type of pump designed to fill a filter press with a slurry or suspension from an external storage or disposal facility, typically used in solid-liquid separation processes, typically at high pressures reaching 24 bar.

Tapflo Filter Press Pumps are known for their robust construction, reliable performance, and ability to handle high-pressure applications with ease. They are equipped with a non-return valve to prevent backflow and are available in various materials to suit different process requirements. Air operated filter press pumps have the unique feature that when the filter press is full, they stop and no additional safety systems are required to shut down the pump (like in case of electrically operated filter press pumps).

Tapflo offers a wide range of centrifugal pumps made of stainless steel and PP and PVDF plastics, including horizontal or vertical pumps, as well as magnetically driven pumps. Available in hygienic and industrial designs, Tapflo centrifugal pumps are among the most versatile pumps currently available on the market.

Hose pump is a type of positive displacement pump that can be used to pump a wide variety of liquids. Tapflo industrial hose pumps use the principle of peristalsis, whereby the deformation and compression of a soft elastomer hose allows the liquid to pass through the device.

Pumps of this type are the best solution for delicate, corrosive, abrasive or dry media, including those containing solid particles. The special design, in which only the hose comes into contact with the pumped product, reduces operating costs by reducing wear on internal components and allows operation in very demanding conditions.

The SOMA SINUSOIDAL Positive Displacement Pump works according the Sinusoidal PUMP principle, which was developed by Manfred Sommer in 1982. The Sinusoidal curve shaped rotor is fitted on a pump shaft. Due to the design, four chambers are created in which the product will be transferred very gently – without any shear or damage to the product.
A scraper divides the suction and the pressure side. The rotor does not run against the housing or the cover. That means, that the housing and the cover will never wear out. SOMA offers an unlimited guarantee for the cover and the housing.

SLES* is an organic chemical compound with excellent cleaning and foaming properties. For this reason, it is commonly used in the production of cleaning agents, soaps, shampoos, and household chemicals. SLES is typically supplied to manufacturers of these liquids at a 70% concentration, and due to its physical properties, such a concentrated solution is difficult to process and must be diluted below 27% before being used in the production line. Our system enables continuous dilution with maximum efficiency and safety, reducing costs for the company in the long term.

Achieving precise mixing of ingredients to obtain the desired final product—while maintaining strict proportions, accuracy, and sequence—poses a major challenge for industrial manufacturers. The mixer was created specifically for this purpose. It is based on a system for diluting concentrated ingredients such as SLES. However, it has been designed in a modular way, allowing us to easily configure the system to meet actual production needs. The ingredients of the final product can be drawn from various types of tanks.
