Flo King BX650 Filter Systems

Equipment Overview | Filter Pump Industries / Penguin Pump | Process Technology


Flo King offers several pump models, as shown below. The flow rate is given in gph (gallons per hour) and LPH (liters per hour). These units can be used as filter systems (with cartridges attached) or just as pumps (without filter cartridges). All employ the same principle of operation and can be used to pump, filter, agitate, and carbon treat.

Selection should be based on a variety of considerations, including: tank size; degree of agitation desired; available space in tank; clearance above tank; temperature; and chemical composition.

Please call for accesories or special applications.

  • The BX650 can be used in tanks as small as 10 gallons to a few hundred gallons (38 to about 1,000 L), depending on tank-turnover and agitation requirements. Pump provides maximum flow rate of 650 gallons per hour (2400 liters per hour) using a motor rated at 1/15th hp (50-watt). A good choice if tank is too large for the Lab Series but too small for the BX1200.


  • Available in CPVC, polypropylene, and PVDF (Kynar) as pump materials of construction. Standard shaft is made of 303 stainless steel covered with Teflon heat-shrink tubing. As a precaution for aggressive solutions that may attack SS, a titanium shaft and a Hastelloy-C276-alloy shaft are available for pump-body lengths of 6, 8, and 10 inches.

Flow Rate:

  • 650 gallons (2400 liters) per hour at 60 Hz. A flow-rate reduction of about 18% (plus or minus 3%) is typical when operating at 50 Hz.


  • 10 feet (3 meters) of head pressure.


  • About 9 pounds (4 kg) in CPVC, depending on pump body length.


Epoxy coated, rated at 1/15th hp (50 watt), single phase, 3000 RPM, TEFC, thermally protected. Electrical cord is 10 feet (3 meters) long. When ordering, specify one of the following three motors:

  • 115 volt, 60 Hz, 2.2 A
  • 115 volt, 50/60 Hz, 2.0 A
  • 230 volt, 50/60 Hz, 1.3A
