Universal® 2 ND Series – Positive Displacement Pumps
The Universal® 2 ND Series positive displacement pumps include advanced technologies, long life features and installation flexibility. Clean-in-Place (CIP) capable with optional flat body profile and free-draining vertical ports. This highly robust pump can run at pressures of up to 500 psi.
Setting the Standard of Performance and Reliability
Waukesha Cherry-Burrell has long led the industry in designing, manufacturing, and applying external circumferential piston (ECP) style rotary positive displacement pumps. The Universal Series offers exceptional installation flexibility with features like bi-directional flow, 3-way universal gear case mounting, and upper or lower shaft positioning.
Built for durability, these pumps thrive in demanding applications with pressure ratings up to 500 psi (34.5 bar), temperatures up to 300ºF (149ºC), and full CIP capabilities. The Universal 2 ND Series has earned a strong reputation for reliability and performance.
Key Performance Features & Benefits
- Starts with filled, settled slurries without damaging pump or seals.
- Dry running capability with water-flushed seals.
- Preserves shear-sensitive products.
- Pulsation-free flow reduces system vibration and wear.
- No internal rotor contact for extended pump life.
- Non-critical shaft timing simplifies maintenance.
- No oil seepage into product zone—eliminates contamination risk.
- WCB single and double mechanical seals optimized for longevity and performance.
- Triple lip seals available for chemically aggressive or COP sanitary applications.
- Rotor/shaft connection sealed from product zone.
Long-Life Features
- Diffusion-hardened surfaces for rotor, body, and cover—ideal for abrasive or chemically aggressive environments.
- Special rotor nut designed for extended service without loosening.
- No bearings in the product zone—minimizes wear and corrosion.
- Large diameter 17-4 PH shafts for increased strength and stiffness, reducing vibration and extending seal life.
- Heavy-duty bearing frame (stainless steel option available).
- Grease-lubricated bearings ensure consistent lubrication across all operating conditions.
- Wave spring loading extends outer seal life compared to traditional O-rings.
- Unique mechanical seal design with 3-pin stationary seal and specialized shaft for rotary seal.
- Double tapered roller bearings provide precise rotor positioning and longer seal life.
