NYP High Viscosity Rotor Lobe Pump
2026-09-29
When Viscosity Changes – Your Pump Must Adapt
Most pumps are designed for one viscosity range. Change the fluid, and performance drops.
The NYP rotor lobe pump was built for fluids that change – and for industries that demand hygiene.
It's a positive displacement rotor pump. No pulsation. No emulsification. No compromise on hygiene.
Built for the Fluids That Matter
| Your Challenge | NYP Answer |
|---|---|
| Wide viscosity range | Adjustable clearance – change viscosity without disassembling the pump |
| Hygienic requirements | 3A standard, SS304/SS316, inner polished – dairy, food, cosmetic, pharma grade |
| High-viscosity media | Positive displacement – handles thick syrups, pastes, and gels |
| Shear-sensitive products | Low-shear rotor design – preserves product texture and quality |
| Temperature control | Insulation jacket available – keeps product hot or cool during transfer |
| Corrosive fluids | Stainless steel construction – compatible with aggressive media |
| High flow rates | Up to 43,000 L/h – handles production-scale transfer |
| Multiple connection types | Clamp, thread, weld, flange – matches your existing piping |
Why Rotor Lobe – Not Centrifugal or Gear
| Pump Type | Limitation | NYP Advantage |
|---|---|---|
| Centrifugal | Cannot handle high viscosity, shear damage | Positive displacement – handles high viscosity, low shear |
| Gear pump | High shear, not hygienic, difficult to clean | Lobe rotor – low shear, hygienic, easy to clean |
| Peristaltic | Tubing fatigue, limited pressure, pulsation | Rigid rotor – no tubing, higher pressure, smooth flow |
| Diaphragm | Pulsating flow, valve wear, limited viscosity | Rotor principle – smooth flow, no valves, wide viscosity |

What Sets NYP Apart
| Feature | What It Means for You |
|---|---|
| Adjustable clearance | Change viscosity without disassembling the pump – simple operation |
| Insulation jacket | Cast into the pump body – no welding, no leakage, excellent thermal insulation |
| Outer rotor drives inner rotor | Same-direction rotation – less wear, longer service life |
| 3A sanitary standard | Meets food, dairy, and pharmaceutical hygiene requirements |
| Multiple rotor options | Single, tri-lobe, butterfly – choose the best fit for your product |
| Wide viscosity range | One pump handles thin liquids to thick pastes |
| Low shear | Preserves product texture – ideal for cosmetics and food |
| Self-priming | Starts without manual priming – reduces operator workload |
| High efficiency | Lower energy consumption for the same flow rate |
Typical Applications
| Industry | Application | Why NYP |
|---|---|---|
| Food and Beverage | Syrup, chocolate, honey, jam, sauce transfer | Hygienic, low shear, 3A standard |
| Dairy | Yogurt, cream, cheese curd, milk concentrate | Gentle handling, CIP-compatible |
| Cosmetics | Cream, lotion, gel, toothpaste transfer | Preserves texture, hygienic construction |
| Pharmaceutical | Ointment, gel, syrup, API transfer | Sanitary, easy to clean, SS316 available |
| Chemical | Paint, resin, adhesive, dye transfer | Corrosion-resistant, handles high viscosity |
| Petroleum | Grease, heavy oil, lubricant transfer | High viscosity capability, insulation jacket available |
| Environmental | Sludge, slurry, wastewater transfer | Handles solids-laden fluids, low shear |
One Question
Would you rather change your pump when viscosity changes – or change the clearance?
Disassembly wastes time. Production stops cost money. Product quality suffers.
Adjustable clearance lets you adapt without stopping.
The NYP gives you the flexibility you need.
