The MIDLAND INDUSTRIES BLAY-300-CASS is a 3-inch nominal water discharge lay flat hose assembly designed for high-volume water transfer in the field. Built with a PVC tube and PVC cover reinforced by woven high-tensile synthetic yarn, this hose delivers reliable flow capacity while laying flat for compact storage and easy transport. C/E camlock fittings on both ends allow for fast, tool-free connection to pumps, tanks, and discharge points. The 50-foot length suits typical dewatering, bypass pumping, and site drainage runs. Rated for temperatures from 15 degrees F to 130 degrees F, it holds up across a wide range of seasonal operating conditions. Plumbers, contractors, and pump service technicians regularly deploy this type of assembly on job sites where quick setup and breakdown are required.
This lay flat hose assembly is suited for water discharge applications in residential, commercial, and light industrial settings. Typical uses include dewatering excavations, draining pools or tanks, bypass pumping during plumbing repairs, and general site water management. The camlock end connections are compatible with standard C/E camlock fittings commonly found on centrifugal and submersible pump systems. Its blue color provides quick visual identification of water discharge lines on multi-hose job sites. The 50-foot length covers most standard pump-to-discharge-point runs without requiring additional couplings.
Designed for use with standard C/E camlock pump and discharge port fittings on centrifugal pumps, submersible pumps, and other water transfer equipment that accept 3-inch camlock connections.
Installation is typically performed by plumbers, pump technicians, or general contractors. Before connecting or disconnecting the hose, shut down and depressurize the pump system. Inspect camlock fittings and gaskets for wear before each use and ensure locking arms are fully engaged before starting the pump. Avoid running the hose over sharp edges or abrasive surfaces, and do not exceed the rated temperature range during operation.
