SH2-M Metallic 2" (50 mm) 2:1 High Pressure  Flap Valve Pump

The SANDPIPER SH2-M METALLIC 2" (50 MM) 2:1 is uniquely designed as the only high-pressure flap valve pump in the world, capable of achieving discharge pressures up to 250 psig (17.2 barg). This AOD pump combines high discharge pressure with superior solids handling, making it ideal for demanding applications such as filter press feeds and high-solids content fluid transfers.     

1/ Key features: 

• High-pressure Performance: Delivers a 2:1 pressure ratio, achieving discharge pressures twitch the inlet pressure, up to 250 psig (17.2 barg)
• Durable and Reliable Construction: 

1. Metallic Seats and Heavy-Duty Flap valves: ensures a secure valve seal for performance under high-pressure conditions.
2. Balanced diaphragm design: minimizes pressure differential, reducing wear and maintenance needs  

• Efficient Maintenance:

1. ESADS+: Provides quick, external access to the air distribution system, enabling repairs or cleaning in five minutes without pump removal. 

• Exceptional Solids Handling: Flap valve design handles solids up to 1.8” (45mm), maintaining efficient flow and preventing clogs in high-solids environments. 
• Optimized Stroke Control: Independently regulated suction stroke control for smooth and adjustable performance. 
• Material Options: Available in aluminum and cast iron with elastomer options to handle various fluid properties. 

2/ Application

• High-Pressure Solids handling: ideal for high-solids fluid application and sludge management 
• Demanding, High-Pressure Applications: Suited for filter press feeds and applications needing higher discharge pressures. 
• Heavy-Duty Industrial Use: Excellent for mining, wastewater, and industrial processes requiring durable, clog resistant performance.
