Features
Designed to transfer fluids containing large solids.
Top inlet and bottom outlet configuration: solids are discharged directly, preventing damage caused by settling inside the pump.
Large internal clearance: allows the passage of solid particles up to 56 mm in diameter, or compressible elastic solids up to 76 mm in diameter.
Excellent performance: the flap valve pump is suitable for fully submerged applications.
Air distribution system serviceable from the outside.
Rotatable inlet and outlet connections; adjustable discharge direction (90° – 180°).
Fully bolted construction: high durability and resistance to high pressure. Easy maintenance.
Higher operating efficiency.
Lower operating costs.
