Fun Facts about Multotec Cyclones

1. Largest and Smallest

Our largest cyclone is the aptly named 1450 DMS “MAX” cyclone. This behemoth has a 1450 mm diameter. The smallest cyclone we supply is a dinky FC25 classification cyclone with a 25 mm diameter. A total 16 233 x FC25s are equal to 1 x MAX1450 in weight. The heaviest cyclone component is MAX145-ZL/A-MSA weighing 1755 kg. The lightest cyclone component is a 4HS spigot weighing 14 g. The Max1450 cyclone has an internal volume of around 6.7 m³.

2. Parts and Permutations

Our cyclone range is very wide to cope with all the varied applications that we could encounter. To make up a single hydrocyclone there are up to 16 major individual parts of varying configurations. The total number of these individual cyclone parts are in the order of 1 500 standard components. The HC range has more than 301 major components and the total number of estimated permutations of a cyclone type configuration (for instance an HC500 classification cyclone) is a mind-blowing 3 936.                                                                                                                  

3. Hydrocylone Birth Dates

The hydrocyclone was born in May 1891 and the technology is 124 years old. The grandchild of hydrocyclones the DMS cyclone was born in February 1951 and is a younger 70 years old.
Multotec first started selling cyclones under the name Multotec Cyclones. This was on an interesting date of the 1st April 1978. Post that the present MPE company came into existence. Our cyclones can be said to rank among the best in the world and we are seen as a serious player, especially in the DMS market.

4. Visits

Pre COVID-19 lockdown the average number of km travelled by a single MPE cyclones engineer in a year was 48 896 km by road and 7 876 by air bringing the total km to 56 722 km. The number of clients seen was 130 and people seen was 325 by this engineer. At present unfortunately due to COVID-19 restrictions these face to face visits are reduced but we are looking forward to increasing these in the coming year.

5. Performance Figures and Installations

The coarsest cut-point for a hydrocyclone application is around 450 µm and the finest cut-point is 5 µm. Note these are not the norm, but interesting none the less. The lowest flowrate for a single cyclone is 0.5 m³/h and the highest flow rate is 35 000 m³/h. Note these are not the same type of cyclone for each. This gives you an idea as to how big 1 µm (one micron) is.

In Southern Africa, the deepest installed Multotec cyclone is on one of the local gold mines at around 2 km underground and the highest is 3.1 km above sea level at the world’s highest diamond mine. Our cyclones do go up higher at times, but that’s when they are being air-freighted to some of our clients.

The most southerly installed cyclones from our Multotec range are at a plant on the Island of Tasmania. The most northerly installed cyclones would be at a plant near Kirovsk (Murmansk region, on the border with Norway), and serviced loyally by our Multotec International team.
