Examples of applications for our pumps

Examples of applications for Ragazzini pumps in the production processes of leading companies in a range of sectors.

Chemical industry

The Rotho peristaltic pump can transfer calcium tartrate and highly abrasive calcium tartrate crystals. Only the tube of the Rotho pump requires maintenance. All other internal components of the pump are maintenance free as, unlike all other types of pump, they never come into contact with the pumped product.

Model: MS2
Product: tartaric acid
Temperature: ambient
Tube: natural rubber (NR)
RPM: 21
Flow rate L/h: 3000
Pressure: 0.5 bars
Suction: positive head
Hours use/day: 24/d

 

 

Ceramic sector

This is an extremely demanding application due to high temperatures, operation in negative head conditions and the presence of highly abrasive products. The Rotho pump replaces a submerged pump with numerous advantages - it is self-priming from -9.5 m, can pump products with suspended solid parts, can operate dry and only the tube requires maintenance.

Model: SF 100
Product: slip
Density: 2
Temperature: 50°
Tube: natural rubber (NR)
RPM: 9 /15
Flow rate L/h: 9,000 L.
Pressure: 4 bars
Suction: - 4.5 m.
Hours use/day: 24/d

Sludge with suspended solid parts

The Rotho peristaltic pump can transfer activated sludge containing solid parts with a dimension up to 45% the bore of the tube without the risk of clogging the tube or damaging the internal parts of the pump which never come into contact with the pumped product.

Model: SF100
Product: sludge
Temperature: ambient
Tube: natural rubber (NR)
RPM: 30
Flow rate L/h: 18000
Pressure: 3" tube, 200 m length
Suction: - 1 m
Hours use/day: 8-10 h/d
