PB0801FNDDN0000 Fluid-o-Tech 260 GPH 4.33 GPM Standard Bypass High Volume Stainless Steel Rotary Vane Pump

Bolt-On 1/2-Inch NPT Vane Pump with Three-Bolt Flange, D Shaft and Built-In Relief Valve

The Fluid-o-Tech PB0801FNDDN0000 is a flange-mount rotary vane pump in the PO 500-1000 high-volume series. It bolts in place through a three-bolt flange and is driven through a D shaft. This is the version used on C-face motors with a bell housing and coupling. The housing is low-lead brass with a built-in relief valve, and the inlet and outlet ports are 1/2-inch NPT.

The pump is rated at 800 L/h (211 GPH) at 1450 RPM and delivers about 250 GPH (4.17 GPM) at 1725 RPM, which is also its speed limit. Maximum static pressure is 290 PSI (20 bar) and maximum differential pressure is 230 PSI (16 bar). The relief valve is adjustable and comes set at 170 PSI (12 bar) unless another setting is ordered. It is there to protect the pump and system from pressure spikes and should not be used to control flow. Liquid temperature can go up to 158°F (70°C).

Inside, a stainless steel rotor (AISI 303) turns carbon graphite vanes in a carbon graphite pumping chamber, and the seal is NBR (Buna-N). PB pumps are NSF 169 listed and meet the low-lead requirements of California AB 1953. Fluid-o-Tech recommends a 10-micron filter on the inlet side and cautions against dry running. Typical uses are post-mix drink dispensers, cooling systems, booster systems, and water treatment, including reverse osmosis.
