Sampling Systems

DPM Back & Needle Purge Configuration (A6)

The ability to back purge the sample point ensures optimal retrieval of a representative liquid sample. The needle purge ensures there is no residue or build up in the needle after sample retrieval. The DPM type sampler in back & needle purge configuration allows purge gas to flow through the sampler ensuring a fresh sample and finally to purge the needle assembly at a recommended maximum operating pressure of 8 bar. This liquid sampler offers one-handle operation, providing safety for the operator and zero emission.

Provide a new septum on your sample bottle. Insert the bottle, with cap and septum into the sleeve until the septum is pierced by the needles. Put the bottle retaining clip in place.

Turn the handle to “back purge” position, allowing a flow of purge gas through the sampler to ensure representative sampling. This position can be held for any required time.

Turn the handle to the “sample” position, allowing the product to flow into the sample bottle. When the required amount has been taken, turn the handle to the “needle purge” position.

Turn the handle to the “needle purge” position, allowing a flow of purge gas through the sampler to ensure any residual liquid is forced into the sample bottle. This position can be held for any required time.

Turn the handle to the “off” position. Remove the bottle retaining clip and pull the bottle out from the sleeve. The septum reseals automatically.
