Centriflo and Series B, low NPSH Pumps

B Series, low NPSH, style PF-B, PVF-B and HB

The B-35 Series pumps has a suction inducer to create a positive pressure at the centrifugal impeller thus guaranteeing low NPSH pump requirements. Pumps require only 2′ NPSH and can pump condensate up to 210°F (99°C) at sea level from a vented tank at the same level as the pump suction. Pumps mounted to a vented tank elevated 24” above the pump suction can pump 212°F (100°C) water. Pumping from closed loop systems is limited to a maximum of 35 PSI suction pressure and may require alternate seals if temperatures exceed 250°F (121°C). Style PF-B vertical pump is available as a flange mounted for connection directly to a tank. PVF-B are vertical pumps for separate standalone floor mounting and HB Horizontal pumps are available for separate mounting. All pumps are bronze fitted with bronze case wear rings, bronze suction inducers, bronze flow straightening vanes and stainless steel shafts.
