Polyurethane Foam


PU Processing Pumps


Consistency and reliability for high speed production lines.

100% leak-free pumping of non-lubricating, highly volatile, flammable and toxic liquids. With no dynamic seals, Hydra-Cell seal-less injection pumps reliably handle liquids with suspended solids, such as filled polyols.

  • 100% safe containment for even the most aggressive liquids.
  • Abrasives, high viscosity handling and accurate metering.
  • Lower initial cost and lower operating and maintenance costs.
  • Meets or exceeds API 675 performance standards.

Reliable pumping of high viscous, corrosive and hazardous liquids


Reliably Pumping Difficult Process Liquids


Additives of many types are often injected as part of the process. Many of these chemicals are corrosive and react with moisture or air to form micron crystals which can be very abrasive e.g. Isocyanates. Hydra-Cell pumps seal-less design and unique check valve design means these types of chemicals can be pumped reliably in high speed production lines.


Polyurethane Processing Applications

  • Pressure injection
    • Polyols
    • Filled polyols
    • Isocyanates - TDI, MDI
    • Blowing agents - pentane, freon
  • Metering & dosing chemicals
    • Catalysts
    • Acids
    • DI water



Extremely Low Pulse Flow Metering & Dosing


In metering and dosing operations the Hydra-Cell has a distinct size advantage over traditional metering pumps, being very much more compact. Not only does it take up less space, it also offers substantial savings on the total costs of pump ownership and operation – including acquisition costs, energy usage and expenditure on maintenance and repair.

Flow is virtually pulse-less, frequently eliminating the cost of pulsation dampeners.


100% Leak-Free


Environmental legislation has forced the move to blowing agents such as Pentane. No leaks can be tolerated in pumping this non-lubricating, highly volatile, flammable and toxic liquid – but the Hydra-Cell’s seal-less design enables the pump to handle Pentane reliably, without difficulty.




• Capable of handling high inlet pressures 17-34 bar

• 100% hazardous vapour containment

• ATEX certification

• Reliably handling of non-lubricating liquids




• Accurate dosing with extremely low pulse

• Exceeds API 675 performance standards

• Elimination of pulsation dampeners


Pumping Suspended Solids


Increased use of filled Polyols means that the injection pumps must be able to pump liquids with suspended solids. Hydra-Cell's seal-less design eliminates seal maintenance when pumping these types of Polyol.




• Pumping high viscosity filled polyols up to 39,000 cP

• Low shear pumping action for shear sensitive liquids

• Reliably handing filled polyols with suspended particles
