Self Priming Pumps

FreFlow –
Self-priming centrifugal pumps for various applications

SPX Process Equipment has many years experience in designing, manufacturing and maintaining self priming centrifugal pumps for contaminated liquids. On the  basis of this experience, the FreFlow pumps were developed to cover a broad field of applications. High priority has been given to the design ensuring easy operation and amazing reliability.

Typical characteristics

• Excellent self-priming ability
• No non-return valve required in inlet
• Oil bath for the mechanical seal
• Ideal for handling contaminated liquids
• Outstanding qualities for liquids containing gas or air 
• Easy maintenance (back pull-out)
• Easy operation
• Mechanical seals to EN12756 (DIN24960)

CombiPrime is a series of self-priming centrifugal pumps, suited for pumping clean or slightly polluted liquids, with low viscosity. The pumps are available in horizontal as well as in vertical construction. The pump’s self-priming ability is performed by a built-in vacuum pump, based upon the liquid ring principle.

Pump characteristics
