Company overview
  AFROMIX, formally Aeromix, has been producing mixing and pumping equipment in South Africa since
  1975. Our products have been supplied into all areas of industry, particularly Mining, Chemicals, Pulp & Paper,
  Pharmaceuticals, Petrochemicals and Waste & Water treatment.

  The company was also responsible for introducing industrial peristaltic pumps to the country. Initially
  introduced as small pumps for metering, dosing, transfer and analysis, the range has grown significantly over
  the years to include larger industrial pumps for the mining industry.

  AFROMIX’s main product lines include AFROMIX agitators and AFROFLEX peristaltic pumps and hoses.

1. AFROMIX Agitators
  AFROMIX manufactures a range of top entry agitators from 0.25kW to 750kW for use in mining, chemical,
  pharmaceutical, waste management and paper industries. The company‘s manufacturing facility in
  Uitenhage, Eastern Cape, was specially chosen due to the availability of high quality machining facilities,
  a competent labour force and shipping access to export markets. This facility manufactures the company’s
  large agitators. The second production facility in Jet Park, Johannesburg, produces the pump range and
  smaller agitators

2. AFROFLEX Peristaltic Pumps and hoses
  The Environmental Pumping Solutions range of peristaltic pumps are marketed and manufactured in South
  Africa under exclusive license to AFROMIX as AFROFLEX Peristaltic Pumps. The extensive range includes
  the largest pump of this type in the world. The L150, with a 150mm discharge, produces a delivery rate of
  135m3/Hr, at a discharge pressure of 7.5 Barg. These units are ideal for thickener underflow applications and
  other density duties.

  The company also manufactures tubes and hoses for most other makes of peristaltic pumps and has the
  expertise to advise on all piping and tubing requirements.

  AFROMIX offers a wide range of AFROFLEX peristaltic pumps and manufactures tubes and hoses to fit all other makes of
  peristaltic pumps
The AFROFLEX L-series

Twice the hose life and half the power of other peristaltics

A world first design

Our AFROFLEX L series pumps offer all the benefits of most other peristaltic pumps, with the additional
advantages of a slower speed for the same flow-rate and rotating rollers for soft hose compression.
These two features offer enhanced hose life and reduced power consumption.

Our pumps will typically displace twice the volume of our competitors’ pumps. We achieve this by making
our pumps slightly bigger so that the pump rollers are in contact with the pump hose for longer periods.
This means that we can run our pumps at about half their speed and still produce the same flow rate.

AFROFLEX pumps use soft-action rotating rollers to compress the hose as opposed to hard, fixed shoes
used in other pumps. The main advantage of our rollers are that they gently rotate as they compress the
hose, losing very little power from surface friction. Most other pumps have a stationary shoe that drags
on the hose surface, creating a high level of wear and friction and significantly increasing power draw.

Our L-Series pump
Why our pumps make a difference
The benefits of roller over fixed shoe design

With the AFROFLEX pump’s rotating, roller design (above left) there is a soft compression of pump
hose with very little fractional drag. This constant rotation also helps to provide a continual source of
lubricant refreshment on the hose face at the point of contact.

This light, compressing action results in the roller design using typically 50% less motor power than
other pumps fitted with a fixed shoe design (above right).

                                                               Tube compression

The peristaltic pump operating principle
The L range of peristaltic pumps operates on the peristaltic principle, which was patented some
75 years ago.

The technical classification for its pumping action is known as positive displacement. This means that
a fixed and known amount of fluid is discharged per revolution of the pump with flow independent of
discharge head. The action is very simple.

Our pumps operate by compressing a specially designed precision ground hose between a set of
rotating rollers attached to a central rotor, and the internal wall of the pump case or housing. The
product to be pumped in the hose is pushed from the inlet side of the pump towards the discharge by
the squeezing or compressing motion of the rollers on the hose as they rotate. Thus it operates in a
similar fashion to the human heart.
