Polyurethane Foam

 

The polyurethane foam industry pumps many different liquids – they may be non-lubricating or viscous and may contain suspended solids. Pumping is often done on high-speed production lines, so reliability and consistency are very important. Seal-less design makes the Hydra-Cell an ideal pump for these applications.

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 pulseless, frequently eliminating the cost of pulsation dampeners.

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.

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.
