The Universal 2 positive displacement pump modified - specifically designed for the pulp and paper industry.

SP Universal 2 Paper Industry Pump

Learn more about our eXpress app pump services.

Specifically engineered for paper mill applications, the SP (Starch Pump) Universal 2 delivers reliable performance in demanding environments. Its ECP (External Circumferential Piston) design offers unique advantages over conventional lobe and progressing cavity pumps.

Key Advantages in Paper Mill Applications

Starts with settled slurries without damaging pump or seals
Can run dry indefinitely with water-flushed seals
Low shear design protects sensitive polymers and cooked starch
Delivers smooth, pulsation-free flow
No internal rotor contact for reduced wear
Shaft timing less critical than lobe pump designs
Typically requires less horsepower than progressing cavity pumps
Bearing isolators available for enhanced durability

ECP Positive Displacement Pump Highlights

Handles settled slurries that jam lobe or progressing cavity pumps
Imparts extremely low shear—ideal for fragile materials
Designed to operate at temperatures up to 300°F (149°C)
Not damaged by hot products
Dry-run capable with flushed mechanical seals—no internal contact
Meets long-standing performance demands of the paper industry

Waukesha Cherry-Burrell, an SPX FLOW brand, has led the industry in designing and manufacturing ECP-style rotary positive displacement pumps for thousands of challenging chemical and industrial applications.
