PVC Prepacked screens consist of a standard, slotted PVC well screen pipe surrounded by a stainless steel mesh designed for setting small diameter groundwater monitoring wells. Sand is packed between the slotted PVC and the stainless steel mesh. Since the sand is packed around the slotted PVC before the well screen is installed, using prepacks guarantees sand will be located directly around the well screen. This makes groundwater monitoring well installation quicker and more efficient than traditional methods.
Di-Corp offers PVC prepack in in 0.5 inch and 2 inch sizes.
The 0.5-inch prepack uses a standard, 0.5 in. Schedule 40 slotted screen with a sand pack and 1.4 in. diameter stainless steel mesh screen on the outside. The 1.4 in. outside diameter can be used with 2.25 in. probe rods for an efficient combination of tooling for easy prepack installation.
The 2-inch slim prepack uses a standard, 2 in. Schedule 40 slotted screen with a sand pack and 2.8 in. diameter stainless steel mesh screen on the outside. The 2.8 in. outside diameter can be used with 3.75 in. probe rods for an efficient combination of tooling for easy prepack installation. The 2-inch prepack is also available with a 3.4-inch OD. The larger OD allows for a greater sand pack around the screen.
