PARVEEN Inverted Dump Bailer is designed to carry heavy viscosity liquids e.g. cement and other fluids to a point in the well bore where they are required i.e. Plugs, Check Valves etc. The dump bailer contents are released from within the bailer’s cylinder by downward jarring. This shears the shear pins and allows a plunger to rapture a shear disc. The contents are then free to flow through the open ended bailer shoes and its ports. The dump bailer is shear pinned to prevent premature rapture of the shear disc. Variable shear pins are available as per customer’s requirement.
