PS820/PS830 Features The Wilden® bolted metal pump, also known as FIT, sets the new standard for pump performance. Featuring an enhanced flow path design, Wilden's bolted-construction pumps offer improved flow rates (up to 35% over competitive models) as well as improved diaphragm life. Wilden's bolted pumps are also designed for superior containment and have the exact bolt down footprint and inlet/discharge connections as Wilden clamped pumps for easy replacement. NPT or BSPT threaded inlet/discharge liquid connections (PS820) DIN or ANSI flanged inlet/discharge liquid connections (PS830) that don't require welding or nipple attachment Featuring the energy-efficient Pro-Flo® SHIFT ADS Greater flow - more gallons pumped per SCFM Reduced air consumption and kilowatt usage Largest chemical compatibilities Portable and submersible Large-solids passage High suction lift Ease of operation and maintenance Flexible internal adjustment on manifolds Increased on/off reliability Longest Mean Time Between Repair (MTBR) Specifications Air Inlet 3/4" FNPT Liquid Inlet 51 mm (2") Liquid Discharge 51 mm (2") Connection Type NPT/BSPT (Threaded)DIN/ANSI (Flanged) Max Pressure 8.60 bar (124.99 psi) Max Diameter Solids 6.40 mm (1/4") Max Suction Lift Capability Rubber: 7.10m (23.30') Dry, 9.00m (29.50') Wet EZ-Install TPE: 7.00m (23.10') Dry, 9.00m (29.50') Wet Full-Stroke PTFE: 6.60m (21.80') Dry, 9.00m (29.50') Wet Max Flow Rate Rubber: 685.00 lpm (181.00 gpm) EZ-Install TPE: 668.00 lpm (176.00 gpm) Full-Stroke PTFE: 655.00 lpm (173.00 gpm) Displacement Per Stroke Rubber: 2.8 L (0.73 gal) EZ-Install TPE: 2.6 L (0.7 gal) Full-Stroke PTFE: 2.5 L (0.65 gal) Wetted Housings Material Ship Wt Aluminum (PS820) 47.00 kg (104.00 lb) Aluminum (PS830) 54.00 kg (118.00 lb) Stainless Steel (PS820) 73.00 kg (161.00 lb) Stainless Steel (PS830) 81.00 kg (178.00 lb) Ductile Iron (PS820) 71.00 kg (156.00 lb) Ductile Iron (PS830) 82.00 kg (181.00 lb) Non-Wetted Housings Description Material Center Section Aluminum, Polypropylene, Stainless Steel Air Valve Aluminum, Anodized Aluminum, Polypropylene, Stainless Steel Air Chamber Aluminum, Stainless Steel Elastomer Options Material Temperature Limits Buna-N -12.00°C to 82.00°C (10.00°F to 180.00°F) EPDM -51.00°C to 138.00°C (-60.00°F to 280.00°F) FKM -40.00°C to 177.00°C (-41.00°F to 350.00°F) Geolast® -40.00°C to 82.00°C (-40.00°F to 180.00°F) Neoprene -18.00°C to 93.00°C (0.00°F to 200.00°F) PTFE* 4.00°C to 104.00°C (40.00°F to 220.00°F) Polyurethane -12.00°C to 66.00°C (10.00°F to 150.00°F) Saniflex™ -29.00°C to 104.00°C (-20.00°F to 220.00°F) Wil-Flex™ -40.00°C to 107.00°C (-40.00°F to 225.00°F) * 4°C to 149°C (40°F to 300°F) - 13 mm (1/2") and 25 mm (1") models only
