How to install Tapflo pumps

The Tapflo pumps are flexible in their ease of installation. The in- and outlet ports are infini-
tely turnable more than 180° in to fit your piping system (PE & PTFE and metal series pumps).

Flooded
The piping system is designed with a positive suction head.
This is the best way of installtion where it is necessary to
completely evacuate all liquid from the container, or where
viscous (thick) products are transfered.

Selfpriming
The Tapflo pump is designed to pull a high vacuum. It is
able to evacuate an empty suction pipe without any da-
mage 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 capability depends on the pump
size (see pages 17, 24, 29)

Submerged
All Tapflo pumps may be submerged into the liquid. It is
important to make sure that all components which are in
contact with the liquid are chemically compatible. The air
exhaust must be led to the athmosphere by means of a
hose.

heavy duty industrial
applications

PE & PTFE series pumps

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

Polyethylene pumps
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 pumps
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.

The PE & PTFE pump range

Guardian alarm system

In case of a diaphragm break, the unit will stop
the pump and turn on the horn or give signal to
PLC. Leaking liquid in case of a diaphragm break,
will remain in the chamber between the wetted
diaphragm and the backup diaphragm. This system
grants for a high level of safety in plants where
liquid is never allowed to leak.

Prevents & contains spills associated

with diaphragm failure in air driven
pumps

Continually monitors barrier pumps,

tanks, vessels & pipe work
for leaks

Inherently safer than other barrier sys-

tems on the market

The Guardian system monitors the pressure in the void cavities of a barrier pump, pipe work, tank or
vessel. If the pressure in the void increases above the set point due to either a media breach or mecha-
nical failure, the system will issue a signal that can be utilised to sound an alarm, stop the pump, etc.
The diaphragm is PTFE faced as per the fluid diaphragms of the pump, therefore is completely tolerant
of most media and is therefore much safer than conventional systems. The guardian body is made from
either aluminium, stainless steel or conductive PTFE.

Pneumatic batch control unit

Just set the desired number
of strokes and press
”start” and the pump will
automatically transfer the
desired volume.

The strokes from the

pump are sensed from the
pressure of the outgoing air.
The system is easy to apply
on all Tapflo pumps.

The pneumatic batch unit allows you to set and pump a certain number of pump strokes - all this without
any electricity. The system is easily applied on all Tapflo pumps. Only the exhaust muffler has to modified
with a hose connection. When the batch is started, the unit will count the number of pump strokes the
pump is doing. The pump strokes are sensed from the variation of pressure in the air exhaust by a pres-
sure switch (placed in the counter unit).

Filling containers of various volumes with a T50

Let 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 record have many strokes the pump needs.
For future batching, just enter the number of strokes and press ”start”. The batch unit will start the pump,
count down and finally stop the pump when the batch is finished.

Pneumatic level control system

The level control system will sense the liquid level

within a few millimetres.

The air supply to the pump is controlled by the level

system

This ingenious system is operated with pneumatic

components only. The level control system may be
installed in sumps, tanks or tubs to start and stop the
pump at certain liquid levels. This system is allowed
for use also in explosion hazardous areas, thanks to
the absence of electricity. 2

Evacuating liquid from a sump

The end of the hose ”low” (1) (or end of extension
pipe) is placed on the desired low level in the sump
and the end of the hose ”high” (2) is placed on the
high level position. As the liquid is reaching the high 1
level hose, the pump will start and pump until the
liquid level is reaching the end of the low level hose.
It is a very accurate system, sensing the levels within
a few millimetres.

Tapflo Pneumix Technology

The Pneumix works both as product transport pump
as well as mixer

The Pneumix...
was predominantly de­veloped for the paint
and ink industry where most raw materials
in drums or containers settle out over time
and need to be mixed or blended prior to
use. This usually means rolling, shaking or
pumping to a mixing vessel; that adds time,
waste, mess and expense.

Increased productivity and reduced waste with Pneumix

The Pneumix utilises the container the product arrives in to mix and dispense and simply fits securely in
the vessels fill hole. Increasing productivity by reducing waste and further product handling.

Some benefits with the Pneumix...

Eliminates problems with conventional mixing

No need for pumping to mixing vessel
No paddles or rotating blades
Fully controllable pneumatic operation and control
No moving parts utilises pump power to mix & dispense
Variable agitation
No shear
No air entrainment
Closed vessel mixing system
Reduced environmental exposure
Increased product life and performance
Suits all containers up to 1000 litre IBC
No modification to vessel
Available in wide range of materials

 Accessories

Tapflo Pneumix Technology

How it functions…
The Pneumix works both as a mixer and as a transfer pump:

Mixing mode
The discharge valve is closed and
the recirculation valve is open, to
allow the product to circulate in
the container

Transfer mode
The discharge valve is open and
the recirculation valve is partially
open, to both mix and to transfer
the product out of the Pneumix

Pneumatic mixing system

Offer enclosed product handling – reducing worker or environmental exposure, spillage and contamina-
tion. Hazardous, sensitive or volatile products are securely protected within their container. All contributing
towards a clean, safe working environment.

Batch and mix

This system allows the product to be mixed and batched when it is needed, reducing time, increasing
product life and minimising waste.

Variable agitation
Means the mixing action can be matched to the specific product or application.

Safety
Air operated control and operation means no electrics are necessary.

Powder pumps

Trouble free, safe and clean transfer of powders

Economical compared with other
complex powder systems

Convenient and safer than

manual powder handling

Reduced contamination
The powder is transferred in a hermetic system
from the powder container to your process.

Economical and
compact solution
The Tapflo powder transfer pump can do the
same job as many complex and large powder
systems. The compact design also makes the
unit portable.

What kind of powders?

The powder transfer pump will handle different
types of process powders, with specific weight
from 80 up to 720 kg/m3 dry weight. Gene-
rally, if the powder does not clump together
when you squeeze it in your hand, the Tapflo
powder transfer pump can be used success-
fully. A few examples of common powders are sintering powder, carbon black, resins and silicones.

Capacity
The capacity of the powder transfer is extremely different from one powder to another, depending on the
consistency and weight etc. Fore more specific information about the capacity in your application, please
contact your local Tapflo distributor, or fill out the inquiry form on our website www.tapflo.com.
