Key benefits
Advantages of Tapflo hygienic diaphragm pumps 1. Quick disassembly
Tri-clamp system ensures quick and easy disassembly without the use of additional tools.
2. Variety of connections
The pump is supplied as standard with SMS3017/ISO2037 clamp connections. However, the pump can be equipped with almost any type of connection used in the hygienic industry – DIN 11851 thread, SMS 1145 thread, DIN 11864 aseptic connections and others.
3. Environmentally friendly pneumatic drive
The air distributor features an oil-free design, leaving the pumped medium and the environment free from contamination.
4. Homogeneous surfaces
Multi-layer diaphragms have a homogeneous surface, which eliminates the problem of bacteria build-up. The diaphragms are made of food-grade materials: PTFE (FDA and USP VI), PTFE 1705B (FDA and USP VI)
5. Perfect finish
Both the wetted and external sides are electropolished for a perfect finish and hygiene. Special surface finish on customer request.

Emptying the Tapflo pump by rotationEasy drainage

Empty the pump by turning it on the stand

To completely disassemble the pump, simply unclip the clamps securing the nozzles and unscrew the bolts connecting the housing. Then simply rotate the pump to pour out the remaining medium.

The design of the pumps in this series allows for full visual inspection of the parts in contact with the pumped medium. There are no hidden spaces where bacteria could grow. The pump can also be cleaned and sterilized directly in the installation (CIP and SIP).

EHEDG Certificate
Aseptic Diaphragm Pumps with EHEDG Certification

The EHEDG (European Hygienic Motorering & Design Group) certificate guarantees that the design complies with hygienic guidelines. Moreover, the pump has successfully passed the cleanability test, which means that bacteria do not develop in the pump after it has been cleaned and emptied.

Operation principle

The Tapflo diaphragm pump is powered by compressed air. Two diaphragms work alternately, pushing liquid into the pumping system. Ball valves act as check valves, directing the liquid in the right direction.

During each cycle, the air pressure behind the discharge diaphragm is equal to the liquid lift height on the medium side. This means that Tapflo diaphragm pumps can operate with a closed discharge valve without negatively impacting diaphragm life.

SUCTION

The retracting diaphragm creates a vacuum, and thus the phenomenon of medium suction.

DISCHARGE

The second diaphragm simultaneously transfers air pressure to the medium in the second diaphragm chamber, pushing it towards the discharge port.

Construction
Magnetic Ball Valve Lifters

The ability to empty the pump contents is crucial in most hygienic applications. The Tapflo ball valve lifting system allows the pump to be emptied without having to dismantle it from the installation when other types of emptying are not possible. This way, the pump can be emptied without having to be turned.

Operating principle:

The ball valve, made of AISI 420 or PTFE with a steel core, is lifted by a magnetic lifter attached to the manifold.

Extended Life Diaphragms

Tapflo diaphragms are composite constructions, ideal for operation in harsh conditions, providing a completely uniform surface in contact with the medium. This avoids leakage through the diaphragm and keeps it clean.

Diaphragms are available in various materials and colors to suit all needs.

Available material versions: EPDM, NBR, FKM, PTFE, PTFE TFM 1705b, white EPDM, PTFE with white EPDM backing, white NBR.

Diaphragms in Tapflo diaphragm pumps
Composite diaphragm construction

The advanced manufacturing, curing, trimming, and finishing process ensures a long service life for the composite diaphragm, which will last for many millions of strokes. The component materials are specially made and adapted to the composite diaphragm technology and the molding process with pressing.
The elements are joined using chemical agents and adhesives.

Air distributors in Tapflo diaphragm pumps Economical Power Supply – Air Distributors

The air distributor, which redirects compressed air to the chambers behind the diaphragms, is the heart of the pump. The distributor is located in the center of the pump between the diaphragms to minimize the air path and dead spots. This design is key to reliable and economical operation. Thanks to a special sealing system, the distributor does not require lubrication. This not only saves money but also protects the environment.

Available material versions: brass, PET, and AISI 316L stainless steel

Ball Check Valves

Tapflo pumps are equipped with four check valves to ensure that the liquid is pumped in the right direction.
Ball valves are the simplest and most reliable check valve design. They are characterized by tightness and ease of cleaning and replacement.

Available material versions: EPDM, NBR, PTFE, PTFE TFM 1635, PE1000, FKM, PU, Ceramic, SiC, AISI 316L.

Alarm system | GuardianTM

The GuardianTM system is an energy-saving device designed to protect an air-operated double diaphragm pump from inefficient operation, which consumes unnecessary energy and shortens the life of parts. It also increases work safety in high-risk applications.

The GuardianTM system monitors the liquid pressure, changing it if the pressure value rises or falls below the set value. It thus controls pumps in the following cases:

  • Barrier protection – Tapflo double diaphragm pumps (TB series barrier pumps) have an additional set of backup diaphragms. In the event of a leak, the liquid remains inside the pump instead of leaking through the air outlet. The system monitors the pressure between the main and backup diaphragms, stopping the pump if the pressure exceeds the set point.
  • Dry start and stop – the system monitors the pump’s liquid discharge pressure. It stops the pump if the pressure drops below the set point, caused by a lack of medium at the suction and air being drawn into the pump.
  • Pump blockage and restart – the system monitors the pump’s liquid discharge pressure. It stops the pump if the pressure rises above the set point, caused by a closed valve or overpressure in the discharge line. If the pressure drops below the set point, the pump automatically resumes operation.

Pneumatic dosing control

The dosing control unit allows you to set any air-operated diaphragm pump to transfer a precisely defined and repeatable amount of medium.
These devices are fully programmable and allow you to set a specific amount (TPUK-BP) or a specific operating time (TPUK-BT).

Pneumatic medium level control

A fully pneumatic automatic system used to maintain a set liquid level in a tank.

Stroke counter/low pressure VFC

A volt-free contact (VFC) stroke counter is available for integration with PLC systems.

Lifetime counter

Indicates the total number of strokes made by the pump throughout its operating life. A compact, easy-to-use system will allow you to control servicing and implement planned preventive maintenance.
