KRAL Pumps with Magnetic Coupling for perfect Polyurethane.

Fillers are increasingly being added to polyurethane and fillers are often abrasive. Fillers bring different values to the PUR properties; fillers are used to reduce combustion and provide better insulating values, and increase strength of the final product.

Abrasive fillers accelerate wear on the mechanical seal, spindles, and the casing of standard pumps.  KRAL recommends the magnetic coupling pump with hardened spindles and pump casings. After consulting with KRAL, the pump design can be planned according to user specification.
 

Your Advantages:

• Pulse free gentle handling of the fluid.
• No damage to the polymer threads.
• No replacement of mechanical seals with the magnetic coupling design.
• Polyol and Isocyanate do not come in contact with the atmosphere.
• Hermetically sealed by vacuum designed assembly. 
• Vertical assembly available.
• Special solutions for raw material producers, machine builders, and component producers.

Note:
KRAL offers PUR equipment, components and raw materials manufacturers also solutions for an exact flow measurement for PUR components.
