For viscous and delicate media
Piston and twin-lobe rotors handle thin and very viscous media alike — curd, whey, fruit or meat — without special rotors.
- Steady, pulse-free flow for fillers and valves.
- Low NPSHr — well suited to ultrafiltration.
- All product-contact parts in AISI 316L.
Why DW rotary lobe pumps
High volumetric efficiency
Minimised clearances — a smaller pump does a bigger pump's job.
Ultra hygienic
CIP and SIP, resistant to thermal shock.
Pulse-free operation
Steady flow protects fillers and valves.
Low NPSHr
Better suction — ideal for ultrafiltration.
Gentle on product
Rotor design protects the integrity of sensitive products.
Quick service
Front-loading mechanical seal, identical shaft O-rings.
