Wilden PS8 XPS8 Pro-Flo – 51 mm (2″) Air operated diaphragm metal pump

Wilden PS8 XPS8 Pro-Flo – 51 mm (2″) Air operated diaphragm metal pump

The Wilden PS8 air-operated double diaphragm (AODD) pump with 2″ (51 mm) ports is designed for heavy-duty industrial applications.
Part of the Pro-Flo SHIFT series, it offers significantly reduced air consumption, higher efficiency and lower operating costs compared to conventional AODD pumps.
The clamped metal design ensures quick and easy maintenance and allows the use of different wetted materials to maximize chemical compatibility.

Main Features

• Maximum flow rate up to 700 l/min with rubber diaphragms, up to 723 l/min with full-stroke PTFE.
• Maximum operating pressure: 8.6 bar (125 psi).
• Solids handling up to 6.4 mm.
• Self-priming capability with excellent suction performance.
• Can run dry for short periods depending on diaphragm material.
• Diaphragms available in EPDM, Buna-N, TPE EZ-Install, full-stroke PTFE and other variants.
• Fluid connections: 2″ threaded (NPT / BSPT) depending on configuration.
• Clamped design allows rapid disassembly with a single tool.

Key Specifications

• Maximum flow rate: ~700–723 l/min depending on diaphragm material.
• Operating pressure: 8.6 bar.
• Solids handling: up to 6.4 mm.
• Dry lift: up to ~7.2 m with rubber diaphragms.
• Wet lift: up to ~9.0 m with rubber or TPE.
• Air inlet: 3/4″ FNPT.
• Manageable viscosity: variable depending on diaphragm type (see datasheet for details).

Benefits

• Reduced air consumption thanks to the Pro-Flo SHIFT system.
• Lower operating costs over time.
• High chemical compatibility with multiple diaphragm materials.
• High reliability with abrasive or solids-laden fluids.
• Easy and fast maintenance thanks to the clamped metal design.

Typical Applications

This pump is ideal for industrial applications such as chemical transfer, wastewater treatment, paints and coatings, food processing (in suitable configurations), mining processes and heavy-duty industries.
It is also suited for fluids containing suspended solids or abrasive media.
