Pumps for Resins, Polyurethane & Polymers
Engineered for shear-sensitive resins, polyols, isocyanates, epoxy adhesives, and hot melts up to 100,000 cSt. Reversible rotation with non-shearing volumetric displacement.
Severe Working Conditions & Engineering Demands
| Key Parameter | Process Value | Engineering Implication |
|---|---|---|
| Moisture Sensitivity (Isocyanates) | Crystallizes instantly upon contact with atmospheric humidity | Requires magnetic drive (mag-drive) sealless execution or double mechanical seal with pressurized oil barrier. |
System Flow Stages & Pump Allocations
Raw Chemical Offloading & Tank Transfer
Unloading viscous polyols, plasticizers, and epoxies from IBC totes and drums into bulk tanks.
Process Pitfalls vs Orbi Pump Engineered Solutions
Isocyanate air crystallization destroys standard shaft seals within days
We offer sealless magnetic drive NYP internal gear pumps. The fluid is hermetically sealed in a containment can with zero atmosphere exposure.
Core Pumps Engineered for this Duty
NYP High-Viscosity Internal Gear Rotor Pump (NYP Series)
NCB Internal Cycloidal Gear Rotor Pump (NCB Series)
3RP Sanitary Cam Rotary Lobe Pump (3RP Series)
G Single-Screw Progressive Cavity Pump (G Series)
Frequently Asked Engineering Questions
Can NYP internal gear pumps handle both polyol and isocyanate?
Yes. For polyol, cast iron or ductile iron NYP pumps with mechanical seals are standard. For isocyanate (MDI/TDI), we recommend stainless steel or ductile iron NYP pumps equipped with hermetic magnetic drive couplings to prevent crystallization.
