Tapflo TC series pumps are based on standard Tapflo air operated diaphragm pumps but fitted with an power pack called LEAP® Technology. The LEAP® technology was developed for a ultra low flow high pressure applications.

LEAP® or ‘Low Energy Air Pump’ is a patented technology used in AODD pumps to reduce the minimum operating air pressure by reducing internal losses and friction found in conventional AODD pumps.
LEAP uses a unique indirect system to detect the position of the diaphragm shaft controlling the diaphragm movement automatically.

Extensive testing procedure showed that a large amount of energy required in a pump was to overcome the resistance in the pump. Another major issue was the mid-port scenario when Air pumps were turned down to much lower air pressure in an attempt to save energy, the pumps simply stalled.

The TC Intelligent pump is able to start pumping at 0.3 bar with no stalling, in test the pump was already achieving flow rates of 70% of its maximum open end flow before other pumps had even started.

The connections may be rotated 180°. Simply turn the connections to fit your piping system. Threaded BSP or NPT connections is standard. Twin connections are also available.

The valve seat is under constant stress from the movement of the valve ball. To obtain the best wear resistant, the integrated seat is made from AISI 316 stainless steel.

The air distribution system is designed with shortest possible air distribution ways. This eliminates “dead spaces”, resulting in high efficiency and low air consumption.

Filter press pump stations

The Tapflo pump station for filterpress feeding is a very compact unit that can be mounted directly to the filterpress. The design and function allows the user a straightforward pressing of slurries.

HOW THEY WORK

Pressure regulator is already mounted to the unit. The pump stations are based on the standard Tapflo pumps from machined polyethylene (PE). An external pressure booster doubles the delivery pressure. For example, with available air pressure of 7 bar, the delivery pressure will be maximum 14 bar.

THE INSTALLATION

As this station works self-regulating, an additional device for regulating the flow quantity is not necessary. Just mount it to the filterpress, connect it – ready.Even the pressure regulator for the air supply is included. For monitoring the filling-level of the filterpress, stroke sensors and stroke counters are available.

PE & PTFE TF PUMP RANGE

Key components of the Tapflo diaphragm pump

* LONG LIFE DIAPHRAGMS

* POLLUTION FREE AIR VALVE

* BALL CHECK VALVES

* CUTAWAY PTFE DIAPHRAGM

Various liquids - Tapflo pumps are compatible with a very wide range of chemicals:

Flammable

Corrosive and chemical aggressive

High and low viscous

Abrasive

Solid content

Shear sensitive

Tapflo pumps made from conductive (carbon filled) plastics PE or PTFE are made for use in explosion hazardous environments. They can be used in Equipment group IIG(gas), CAT 2 (zone 1).

The conductive material ensures that no electrostatic loads will be accumulated in the pump. The conductive pigments in the material reduces the surface resistance to less than 105 W.The pigments, causing the black colour, does not affect the chemical resistance of the thermoplastics.

The TX pumps have diphragms in PTFE (with conductive back) or EPDM (conductive). An earth connection is mounted on the pump, for earthing of electrostatic loads.

Transfer of alcohol and solvents are examples of applications for the Tapflo TX pumps.

All PE & PTFE series pumps are available as TX pumps.

The ATEX directive (also known as ATEX 100a) is applicable on products used in explosion hazardous zones. This directive also covers non electrical products, like our diaphragm pumps.

From July 2003, it is mandatory within the EU to have ATEXcertificate on products which are intended for use in EX-zones.

There are three main categories (zones) in the ATEXdirective:
• CAT 1 (zone 0), flammable material present continuously or for long periods

• CAT 2 (zone 1), flammable material present occasionally in normal operation
• CAT 3 (zone 2), flammable material present in abnormal conditions for short periods

Tapflo PE & PTFE series pumps may be fitted with double in/outlet to achieve ”two pumps in one” for blending, mixing or recirculation of liquids. The liquid in one pump chamber is separated from the other one.

The Tapflo drum pump is ideal for mobile use. It is fitted with a drum tube in polypropylene (PP) or PTFE and a handle in stainless steel AISI 316L. The drum tube is delivered in any length up to 2 m. Tapflo diaphragm drum pump has many advantages compared with conventional drum pumps.
