Bunker sampler for return line sampling

[Purpfox]

I've got a 20k Hp gearbox that I am trying to assist in setting up a return line sample on. Dry sump box with 20" drain. Wondering if anyone on the industrial side has used this type of sample device for getting quality samples.

What type of pressure/suction does your sampling location see?

Do you want to sample after the pressure pump, or on the return line coming from the gear box?

What type of filtration system is currently in place?

The return is no pressure. The oem provided sample legs right before the sump. They are too long and not showing good data. The filters are hydac 1700r010 on/po. We've been plugging the filters with iron deposits.
The system uses a dry sump, so with multiple return lines. I take one post filter and currently 3 drain samples. Filters definitely do the job, system flows 325gpm. But with the way i have to get the drains im losing a lot if data.
