Eccentric Disc Pumps
Eccentric disc pumps are hygienic positive-displacement pumps designed for gentle, low-pulsation transfer of liquids and viscous products. They’re often chosen when you need consistent flow, careful product handling, and CIP/SIP-friendly cleanability.
What are eccentric disc pumps and how do they work?
An eccentric disc pump uses a single eccentrically mounted disc that rotates within the pump casing. As the disc turns, it creates sealed pumping chambers that expand on the inlet side (drawing product in) and contract on the outlet side (pushing product out).
This geometry produces smooth, low-pulsation flow compared with many other PD pump types, and can be well suited to shear-sensitive products (duty dependent).
Eccentric Disc Pump Typical applications
• Food & beverage: dairy products, creams, sauces, syrups, chocolate, fruit preparations (with appropriate configuration)
• Pharma/biotech & personal care: creams, gels, lotions, hygienic transfer of high-value products
• Process/industrial: viscous fluids and suspensions where controlled, gentle PD transfer is preferred (duty dependent)
Why buy eccentric disc pumps from Triark?
Triark can support pump selection, spares supply and aftercare—helping you match the right pump size and configuration to your flow, pressure, viscosity, product sensitivity and cleaning regime, then supporting uptime with service parts and technical help.
Eccentric disc pump spares and service
Common wear/service items include:
• Mechanical seals
• O-rings/gaskets
• Bearings/gearbox oil (where applicable)
• Disc and casing wear surfaces / clearances (especially with abrasive products or solids)
Repair and maintenance
Good practice includes:
• Monitor seal leakage, noise/vibration, and changes in flow at constant speed
• Avoid dry running and deadheading (use pressure protection on PD pumps)
• Maintain good suction conditions to prevent starvation and reduce seal wear
• Keep CIP/SIP parameters within seal/elastomer limits
