Mactenn Product Range

MINIMAXFLO®

The MiniMaxflo® is a sensible altenative to high material
conveying systems, such as lean-phase and medium-
phase pneumatic conveying systems. High efficiency
material transfer without material degradation is achieved
in a very compact, low cost system.

This is a perfect
choice for low transfer rate requirements for fragile and
abrasive materials.

MAXFLO®

The ultimate system for handling difficult-to-convey
materials and hot, abrasive and wet materials, or for
providing gentle handling of products to prevent
degradation of friable materials or separation of blended
materials.

MINIMAXFLO®

The MiniMaxflo® is a sensible altenative to high material
conveying systems, such as lean-phase and medium-
phase pneumatic conveying systems. High efficiency
material transfer without material degradation is achieved
in a very compact, low cost system.

This is a perfect
choice for low transfer rate requirements for fragile and
abrasive materials.

SUPERMAXFLO®

The SuperMaxflo® achieves a solid dense phase
conveying regime for very low material velocities, with little
or no degradation of the most fragile materials, such as
food products.

MACPUMP® & VARIFLO®

The Macpump® conveys high capacities over great dis-
tances. It is capable of conveying materials such as
cement, lime and fly ash at rates of 250 t/h up to dis-
tances of 2,000 m.

The Variflo® is a continuous transfer system for longer
distances and rates in excess of the Maxflo® range.

MAXSANDFLO®

Designed specifically for dry sand _ conveying,
MaxSandflo® is based on proven dense phase pneumatic
principles. Air introduction, simplified system controls, and
top discharge have been designed specifically for this use.
MaxSandflo® can be manufactured without custom
modifications and sold ‘off-the-shelf’ for fast, easy
installation.

MULTIASHFLO®

Designed specifically for conveying hot, abrasive ash,
MultiAshflo® conveys bottom ash, clinkers or fly ash from
fluid boiler beds, baghouses or electrostatic precipitators
at temperatures up to 350 °C. It may be arranged in
multiples of one to 10 units in a single line. lt uses about
50 % less power than existing fly ash conveying systems.

MACTENN INFLATEK® VALVE

Mactenn Inflatek® Valves are fitted to all the Mactenn dense phase pneumatic conveying systems. Used in a variety of applications in almost every process, the Mactenn Inflatek® Valve enables continuous reliable operation, where conventional valves fail to perform.

Other benefits include:

®@ continuous wear compensation when handling abra-
sive materials or operating under high pressure
differential.
_________________________________________________________

M™@ inflatable seal provides compensation throughout
temperature range of 0 °C to 350 °C.
_________________________________________________________

™@ closes and seals through packed material.
_________________________________________________________

™@ seal protection by cleaning ring removing particles
adhering to the dome surface.

M®@ reliability — heavy duty valve rated for hundreds of
thousands of cycles between inspections in approved
applications.

PRESSURE TIGHT SEALING

The inflatable flexible seats entrap particles that are nor-
mally the cause of seat erosion. Particles are induced to
move across valve seats under the influence of pressure
differentials on either side of the closing member.
Entrapping particles within a flexible face during the
period of valve closure, prevents particle movement and
considerably reduces valve seat wear. Inflatable seats
allow automatic wear compensation. The seal is easily
removed for inspection.
