General
How Tapflo pumps workThe Tapflo diaphragm pump is driven by compressed air. The two diaphragms, connectedby a diaphragm shaft, are pushed back and forth by alternately pressurising the airchambers behind the diaphragms using an automatically cycling air valve system.
First cycle... Second cycle...
Suction (1)One diaphragm creates asuction action when beingpulled back from thehousing.
Discharge (2)The other diaphragmsimultaneously transmits theair pressure to the liquid inthe housing, pushing ittowards the discharge port.
During each cycle the airpressure on the back of thedischarging diaphragm isequal to the head pressure onthe liquid side. Tapflodiaphragm pumps cantherefore be operated againsta closed discharge valve withno adverse affect to the lifeof the diaphragms.

General
How to install Tapflo pumpsThe Tapflo pumps are flexible in their ease of installation. The in- and outlet ports areinfinitely turnable more than 180° in to fit your piping system (PE & PTFE and metalseries pumps).
FloodedThe piping system is designed with a positive suctionhead. This is the best way of installtion where it isnecessary to completely evacuate all liquid from thecontainer, or where viscous (thick) products aretransfered.
SelfprimingThe Tapflo pump is designed to pull a high vacuum. It isable to evacuate an empty suction pipe without anydamage to the pump. The suction lift is up to 5 meter(16.4 ’) from an empty suction pipe and up to 8 meter(26.2’) from a wetted pipe. The suction capabilitydepends on the pump size (see pages 17, 24, 29)
SubmergedAll Tapflo pumps may be submerged into the liquid. It isimportant to make sure that all components which arein contact with the liquid are chemically compatible.The air exhaust must be led to the athmosphere by meansof a hose.

General
Key components of the Tapflo pumpThree major components are especially vital for the function of the pump...
Long life diaphragmsThe two diaphragms are doing the work to primeand push the liquid through the pump system.Tapflo diaphragms are of sandwich compoundconstruction, superior for continuous heavy dutyservice. The solution with an integrated metalcore, provides a completely smooth surface incontact with the liquid, without any nuts orwashers. This results in no leak through and adiaphragm which is easy to keep clean. Thediaphragm is available in PTFE(food grade), EPDM, whiteEPDM (food grade), NBR(nitrile) and FKM (viton,on certain modelsonly).
Pollution free air valveThe air valve is the driving heart of the pump,distributing the compressed air to the chambersbehind the diaphragms. It is made formaintenance free duty with no lube air, thanksto the ingenious sealing system. It will not onlysave your money for lubrication, it will also saveyour environment from pollution. The Tapflo airvalve has no deadlock position – the pump willalways start automatically when air is suppliedto the pump. The valve body is made from brassor optional stainless steel AISI 316.
Ball check valvesThe Tapflo pump is fitted with four check valves,making sure that the liquid is transferred in theright direction through the pump. The valve isof ball valve type, the most simple and reliablevalve design. It has a good sealing capabilityand is easy to keep clean and to replace ifnecessary. The valve ball is available in EPDM,NBR (nitrile), PTFE, AISI 316, polyurethane andceramic to suit any kind of liquid.

PE & PTFE series
Pe & PTFE series pumpsTapflo pumps made from polyethylene (PE) or PTFE are suitable for handling almostany kind of liquid whether it is viscous, chemically aggressive or with solids.
Polyethylene pumpsPolyethylene (PE HD) has a superior wear resistance which is 6 – 7 times better than forpolypropylene (PP). This fact makes the pump suitable for handling abrasive slurriesetc. PE is resistant to most kind of aggressive chemicals such as concentrated acids andalkalis. Maximum liquid temperature is 70°C.
PTFE pumpsPTFE (virgin polytetrafluorethylene) is a thermoplastic polymer with superior chemicalresistance. The PTFE pump will handle even the most aggressive acids, for instanceconcentrated nitric acid. Maximum liquid temperature is up to 100°C.

PTFE coated pumpsAluminium pump include allwetted parts coated with PTFE, isequipped with stainless steel in/outlet ports. The model wasdeveloped for the printing industrywhere a low price alternative ofthe PE/PTFE pumps was requiredbut aluminium not chemicallyresistant. It can be used for all sortsof applications where slightlyacidous or alkaline liquids needto be transferred.
However, in applications withhighly aggressive chemicals, westill recommend our full plastic PE& PTFE series pumps.

Active pulsation dampeners
Active pulsation dampener inPE or PTFE.
Active pulsation dampener in aluminiumor stainless steel AISI 316.
The active pulsation dampener is the mostefficient way to remove pressure variationson the discharge of the pump. The Tapflopulsation dampener works actively withcompressed air and a diaphragm,automatically setting the correct pressureto minimise the pulsations. The pulsationdampener is available for all Tapflo pumpsizes and material versions.
How it worksWhen the liquid pressure falls in the pipingsystem, the pulsation dampener supplyextra pressure to the discharge betweenthe pump strokes by displacing liquid bymeans of diaphragm movement. Thispumping action created by the dampener,decreases the pressure variations andpulsations.

This system will imme-diately alarm and shut ofthe pump at an eventualdiaphragm break. It ensuresthat no liquid will leak tothe environment or to the airsystem of the pump - aperfect system where yourequire a high level ofsafety.
The system consists of a backup diaphragm pump (TB), and a control and alarm sys-tem. Under normal operation, the chamber between the backup diaphragm and thewetted diaphragm is set to vacuum by the control system. If any of the diaphragmswould break, the pressure will rise in the vacuum chamber. The control system willthen switch of the pump and turn on the horn. This system is allowed for use also inexplosion hazardous areas, since only pneumatic components are used.

Pneumatic diaphragm alarm system
In case of a diaphragm break, the unit willstop the pump and turn on the horn.
Leaking liquid in case of a diaphragm break,will remain in the chamber between thewetted diaphragm and the backupdiaphragm. This system grants for a high levelof safety in plants where liquid is neverallowed to leak.

Pneumatic batch control unit
The pneumatic batch unit allows you to set andpump a certain number of pump strokes - all thiswithout any electricity. The system is easilyapplied on all Tapflo pumps. Only the exhaustmuffler has to modified with a hose connection.When the batch is started, the unit will count thenumber of pump strokes the pump is doing. Thepump strokes are sensed from the variation ofpressure in the air exhaust by a pressure switch (placed in the counter unit).
Filling containers of various volumes with a T50Let us say that you are using a T50 to fill containers of the sizes 5, 10 and 25 litres.What you first once have to do is to manually prime the different volumes and recordhave many strokes the pump needs. For future batching, just enter the number of strokesand press ”start”. The batch unit will start the pump, count down and finally stop thepump when the batch is finished.

Pneumatic level control system
This ingenious system is operated with pneumaticcomponents only. The level control system may beinstalled in sumps, tanks or tubs to start and stopthe pump at certain liquid levels. This system isallowed for use also in explosion hazardous areas,thanks to the absence of electricity.
Evacuating liquid from a sumpThe end of the hose ”low” (1) (or end of extensionpipe) is placed on the desired low level in the sumpand the end of the hose ”high” (2) is placed on thehigh level position. As the liquid is reaching thehigh level hose, the pump will start and pump untilthe liquid level is reaching the end of the low levelhose. It is a very accurate system, sensing the levelswithin a few millimetres.

Tapflo Pneumix Technology
The Pneumix...was predominantly de-veloped for the paint and inkindustry where most rawmaterials in drums or contai-ners settle out over time andneed to be mixed or blendedprior to use. This usuallymeans rolling, shaking orpumping to a mixing vessel;that adds time, waste, messand expense.
The Pneumix works both asproduct transport pump as well asmixer
Increased productivity and reduced waste with PneumixThe Pneumix utilises the container the product arrives in to mix and dispense andsimply fits securely in the vessels fill hole. Increasing productivity by reducing wasteand further product handling.

Tapflo Pneumix Technology
How it functions…The Pneumix works both as a mixer and as a transfer pump:
Mixing modeThe discharge valve is closedand the recirculation valve isopen, to allow the product tocirculate in the container
Transfer modeThe discharge valve is openand the recirculation valve ispartially open, to both mix andto transfer the product out ofthe Pneumix
Pneumatic mixing systemOffer enclosed product handling – reducing worker or environmental exposure, spillageand contamination. Hazardous, sensitive or volatile products are securely protectedwithin their container. All contributing towards a clean, safe working environment.
Batch and mixThis system allows the product to be mixed and batched when it is needed, reducingtime, increasing product life and minimising waste.
Variable agitationMeans the mixing action can be matched to the specific product or application.
SafetyAir operated control and operation means no electrics are necessary.

Powder transfer pumps
Trouble free, safe and clean transfer of process powders
Economical comparedwith other complexpowder systems
Convenient and saferthan manual powderhandling
No start up problemsThe air induction system eli-minates powder pack upproblems when starting thepump. Air is induced to thepowder side of the pump for dif-fusion of the powder. Theinduction flow can manually beadjusted by means of a needlevalve to obtain a optimumperformance.
ReducedcontaminationThe powder is transferred in ahermetic system from the powdercontainer to your process.
Economical andcompact solutionThe Tapflo powder transfer pumpcan do the same job as manycomplex and large powdersystems. The compact design alsomakes the unit portable.
What kind of powders?The powder transfer pump will handle different types of process powders, with specificweight from 80 up to 720 kg/m3 dry weight. Generally, if the powder does not clumptogether when you squeeze it in your hand, the Tapflo powder transfer pump can beused successfully. A few examples of common powders are sintering powder, carbonblack, resins and silicones.

Powder transfer pumps
Tapflo powder transfer technology
How it worksThe powder transfer pump is based on a standard Tapflo air operated diaphragm pump.The powder is transferred by means of two diaphragms, which alternately prime thepowder from the container in the first cycle and discharge to the process in the secondcycle.
CapacityThe capacity of the powder transfer is extremely different from one powder to another,depending on the consistency and weight etc. Fore more specific information aboutthe capacity in your application, please contact your local Tapflo distributor, or fill outthe inquiry form on our website www.tapflo.com.
Safe in EX-zonesThe powder transfer pumps are ATEX marked, allowing use in explosion hazardouszones (group IIG/IID, category 2).
Available models - dataThe powder transfer pumps are modified from the standard PTFE coated aluminiumseries. The PTFE coating enables an efficient transfer through the pump, with leastpossible resistance.
