Mungo 1690008 (MIT-AP-D1)

Professional Summary

• Manufacturer: Mungo (Switzerland)

• Model/Article: 1690008 (MIT-AP-D1)

• Type: Professional Manual Blow-Out Pump for Borehole Cleaning

• Quantity: 1 piece

Technical Specifications

• Compatible Drill Hole Diameters ($d_0$): Sized and calibrated for boreholes ranging from 8 mm up to 20 mm.

• Tube/Nozzle Length: Approximately 300 mm extension tube, allowing the tip to reach the very bottom of deep structural drill holes.

• Build Quality: High-grade, impact-resistant plastic cylinder housing paired with an ergonomic plunger handle and a heavy-duty seal design optimized for maximum volume displacement per stroke.

Key Benefits & Technical Significance

• Targeted Dust Evacuation: Standard drilling leaves a massive volume of compacted, fine concrete dust at the base of the hole. The extended nozzle of the MIT-AP-D1 bypasses the upper throat, delivering a high-velocity air blast directly to the bottom to force all residual debris upward and out.

• Mandatory for ETA Approval Compliance: In chemical anchoring, sub-surface dust functions as a severe bond-breaker. Injecting resin into an un-blown hole can degrade ultimate load-bearing capacities by up to 80%. This pump ensures the chemical mortar cures against clean, structural parent material.

• The "Blow-Brush-Blow" Protocol: Specifically designed to execute approved job site cleaning procedures (e.g., 2x blowing, 2x brushing, 2x final blowing) before resin application.

Application: Universal requirement across commercial construction, framing, and architectural installations for cleaning drilled holes in solid concrete, solid masonry, tuff stone, or hollow brick. Used immediately prior to the injection of any Mungo MIT chemical mortar system to secure threaded rods, rebars, or internal sleeves.
