Heavy Duty Flap Valve Pump

Sandpiper Heavy Duty Flap Valve AODD Pumps are engineered for the toughest fluid handling applications involving abrasive slurry, large non-suspended solids, and fast-settling materials. Unlike standard ball valve pumps, the flap valve design creates a larger flow path that allows line-size solids to pass through more easily, reducing clogging and downtime. With bottom discharge porting, superior dry suction lift up to 24 ft, and strong dry-run capability, these pumps are ideal for sump applications, mine dewatering, wastewater treatment, and chemical processing.

Widely used across Malaysia and Southeast Asia, heavy duty flap valve pumps are the preferred solution for industries requiring reliable solids handling and long service life. Available in metallic and non-metallic construction, Sandpiper flap valve pumps deliver excellent performance for mining, palm oil mills, wastewater plants, and heavy industrial operations where standard AODD pumps are not enough.
