Product description

Cleanly metered!

Metering lances and non-return valves are fitted in closed pipe systems to prevent mixing and backflow into the metering line. They prevent deposits at the point of injection.

The benefits for you

Variable immersion depth
Suitable for different sizes of hose
Prevents deposits
No backflow

PPE Injection Lance

For immersion depths of 20 - 165 mm, in large diameter pipe to prevent chemical deposition at the point of injection.
