- Hot water
- Heat transfer fluids
Design mechanical seal 4hl
- Single mechanical seal
Technical Data mechanical seal 4hl
- Operating pressure:
Up to 40 bar dynamic
Up to 60 bar static - Temperature: -10 °C to 130 °C
Benefits mechanical seal 4hl
Single mechanical seal, bi-directional and balanced. The shaft protecting sleeve is integrated in the mechanical seal.
The materials selected are optimally suited to seawater applications. Springs made of Hastelloy, all metal components made of super duplex steel.
Dynamic design with multi-spring arrangement. The modular design facilitates installation without assembly fixtures or adjusting dimensions.
Compact seal 4hl
Single mechanical seal, tailored to the seal installation space and pump requirements.
Dependable mechanical seal 4hl
Dynamic type, multi-spring arrangement, bi-directional and balanced. Sturdy and practical seal design.
Versatile mechanical seal 4hl
If combined with a suitable pump design, the seal is suitable for fluid temperatures of up to 350 °C.
Easy to install I mechanical seal 4hl
Standard mechanical seals to EN 12756 would additionally require a shaft sleeve for balancing.
This component is already integrated in mechanical seal type 4HL, resulting in various advantages, also for seal installation.
Easy to install II mechanical seal 4hl
Circumferential groove at the primary ring carrier facilitates setting the axial pre-load of the mechanical seal.
