Reliable Polyol Pumping with O-Pro® Seal Technology
Polyols are easy to handle, but choosing the right pump and seal is key to long-term reliability. Viking Pump’s internal gear pumps offer durable construction and precise flow control, ideal for polyol applications. Their patented O-Pro® Seal enhances leak prevention and reduces maintenance, while enabling standardized pump configurations across polyol and isocyanate systems—simplifying inventory, training, and ensuring consistent performance.
1124A SERIES™
- Rugged design provides superior performance in many markets
- Tight clearances offer high efficiency and excellent priming capabilities
- O-Pro® Barrier combines reliable sealing with easy maintenance
- O-Pro® Barrier is standard with FKM elastomers

Tough Performance for Filled Polyol Applications: 4624B Series™
Filled polyols are highly abrasive, demanding specialized equipment. Viking Pump’s 4624B Series™ is built for the challenge, featuring hardened components and a rugged internal gear design that ensures consistent flow, reduced maintenance, and long service life—even in high-viscosity, continuous-duty environments. It’s the reliable choice for high-load urethane foam production.
4624B SERIES™
- Ultra-hard tungsten carbide idler pin and tungsten carbide idler bushing minimize wear in this key area, since a constant supply of abrasive material is flowing through the pumping elements.
- Behind-the-rotor pinned-seat mechanical seal with hard silicon carbide vs. silicon carbide seal faces, featuring external flush line from pump discharge to remove solids build-up, ensuring longest possible seal life (note: no flush line on F & FH sizes).
- The grease-lubricated bracket bushing is not contacted by the pumped liquid, for long life. The pump is re-greasable, with a lip seal at the stuffing box.

Sealless Solutions for Isocyanate Applications: 895 & 8124A Series™
Isocyanates like MDI and TDI are moisture-sensitive and difficult to handle. Viking Pump’s 895 and 8124A Series™ magnetic drive pumps offer a sealless design that eliminates leak risks and seal failures, ensuring safe, reliable containment. With no dynamic seals to maintain, these pumps reduce downtime and maintenance—ideal for both batch and continuous isocyanate processes.
8124A SERIES™
- Sealless mag drive eliminates the shaft seal to provide the highest level of liquid and vapor containment
- All liquid and vapor is hermetically sealed in the pump
- Used especially for hazardous and difficult-to-seal liquids
