Flomatic Corporation introduces a new 1" & 1¼" Model 80DI VFD patented submersible pump check valve for use with variable-frequency drive (VFD) control submersible pumps.
The PITCHER SAMPLER is designed to recover accurate samples from formations that are too hard for thin-wall shelby samplers or too brittle, soft or water-sensitive to permit satisfactory recovery by conventional core barrel type samplers.
