Diaphragm Pumps

The patented non-stalling, lubrication-free air valve system of Versamatic’s 1" (25mm) bolted plastic air-operated double-diaphragm (AODD) pump provides excellent chemical resistance for pump longevity and reliability. The 1” is available in multiple porting configurations for ease of installation and application flexibility. The rugged, leak-free construction of the 1" bolted plastic diaphragm pump has a flow rate of up to 43 gpm (163 lpm).

Versamatic’s 1 ½" (38mm) bolted plastic air-operated double-diaphragm (AODD) pump offers installation flexibility with adjustable porting options (horizontal and vertical). The 1 ½" AODD pump:

1. Maximum flows up to 100 gpm (378 lpm)
2. Chemically resistant all plastic design (Fluid Side / Air Side)
3. Class-leading solids handling up to 0.47 inches (12 mm)
4. Industry-leading displacement per stroke of 0.43 Gal. /1.63 L
5. Delivers consistent on/off reliability
6. Provides excellent chemical resistance
7. Conductive Polypropylene ATEX compliant models available
8. Safe leak-free bolted design

1 1/2" bolted plastic AODD pumps consist of polypropylene and polyvinylidene fluoride (PVDF). Polypropylene is a thermoplastic polymer that resists strong acids and alkali. PVDF is a durable fluoroplastic with excellent chemical resistance, high tensile strength, and impact resistance. PVDF is best suited for UV applications. With excellent chemical resistance, the 1 1/2" all plastic pump is ideal for aggressive chemical transfer, waste treatment (filter press) applications, and metal finishing. In addition, this pump is engineered to supply high flow rates in a portable size.

SANDPIPER pumps are evolving to perform better than ever. Introducing the new, patent pending SANDPIPER EvolutionX 1" pump, the first to launch in a series of pump sizes. This innovative air operated double diaphragm pump design is the culmination of over 55 years of industry leading research, development and engineering in pump & fluid dynamics. The EvolutionX represents the pinnacle of performance, efficiency and serviceability.

HOW YOU WILL BENEFIT FROM THE SANDPIPER EVOLUTIONX AODD PUMP

Enhanced Convenience: Exponentially reduce AODD pump assembly and service time:

• Reduced service time – EvolutionX takes, on average, five minutes to service the air distribution system compared to 45 minutes on average for other AODD pumps.
• Serviceability – All of the wet side nuts and bolts are the same size & length, and the use of washers has been eliminated. In fact, the EvolutionX has 50% fewer fasteners than the previous model.
• Accessibility – You can access airside components by removing only four bolts revealing an easily removable cartridge-style main air valve and pilot valve assembly.
• Improved stability for increased safety – We have added “stand-off feet” to the inner chambers to stabilize the pump on the workbench during disassembly.

Superior Performance & Efficiency: Improve overall efficiency and safety during operation while decreasing operating costs due to:

• Lower energy use – Achieves an incredible 20% average increase in air efficiency throughout the entire curve over our prior model.
• High flow – The EvolutionX has the highest flow rate of any other 1" AODD pump.

Increased Versatility: Meet countless configuration and application needs with interchangeable components, featuring:

• Durable, non-metallic construction rated for operation up to 125 psi with ATEX versions available.
• Numerous porting options:
  • The standard EvolutionX configuration features a versatile 3-piece manifold with a universal ANSI & ISO flanged connection.  Users can quickly adjust the discharge outlet for porting in multiple directions.
  • Other porting options include a single-piece end-ported manifold or a dual-ported option to accommodate mixing or processing two fluids with a single pump.
• The mounting feet are extremely versatile and fit existing SANDPIPER pumps and multiple other manufacturers’ dimensions.
