Technical Data
The FreFlow range consists of 19 pumps with connections from 32 mm to 150 mm, with a capacity of up to 300 m3/h and a delivery head of up to 70 meters. The self-priming ability is 7 meters. The maximum system pressure is 9 bar and the pumps can transport liquids with a viscosity of max 150 mPa.s. The pumps in the FreFlow programme offer flexible operation thanks to the different drive possibilities
| FRE | Pumps with bearing bracket |
| FREF | Pumps coupled to a flange motor on extended shaft |
| FRES: | Pumps coupled to IEC standard motor |
| FREM | Pumps coupled to a petrol or diesel engine |
FreFlow pumps are self-priming centrifugal pumps suitable for handling contaminated and low-viscosity liquids. Its innovative design, eliminating the need for a non-return valve, results in less maintenance. Oil bath lubrication on the atmospheric side of the mechanical seal prevents dry running during the self priming period. The capability of handling gaseous liquids ensures smooth and continuous operation.
The basic pump is available in cast iron, bronze or stainless steel. Thanks to its high-quality material, the stainless steel version is excellent for handling aggressive, corrosive and environmentally harmful liquids.
Typical industries are: chemical, petro-chemical and pharmaceutical industry, oil, gas and electricity generation, paper, plastic, paint and metal finishing industry and shipbuilding.
The combination of its easy maintenance and operation, make the FreFlow a suitable pumping solution for a large number of applications.
