BF SERIES
BOOSTER PUMPS
With Magnetic
Flow
Switch Controllers |
 |
 |
Davey BF multistage booster
pumps give you strong, even water pressure for shower and
irrigation systems with existing incoming pressure.* Perfect
for today's new multi-shower head showers.
Magnetic Flow Sensor starts the pump whenever the water flow exceeds 1.2 gpm and
keeps the pump running until the flow rate drops below 0.5 gpm.
Typical applications include:
- Multi-jet showers
- Irrigation
Davey
BF booster pumps are economical, compact, quiet,
efficient, stainless steel pumps. Easy to
install, needing no adjustment and requiring very little maintenance. Can be used
with water temperatures up to 150°F. Their corrosion resistant
construction can handle hard and acidic water supplies.
*
Note: Because the BF series uses a flow control, they
require a minimum of 20 psi incoming pressure for the flow control to
operate consistently. NOT
FOR SUCTION LIFT APPLICATIONS.

 NOTE: DO NOT EXCEED A TOTAL PUMP PRESSURE OF 100 PSI. The total
pump pressure will be the inlet pressure + maximum boost pressure from the
table above. Municipal water supplies can vary over a 24 hour period and
in some applications a Pressure Regulator installed before the booster
pump may be required to restrict the inlet pressure and prevent damage to
the booster pump.
KNOW YOUR BUILDING CODES:
The International Residential Code and most local building codes limits the
static (no flow) pressure to 80 psi for residential household use. In some
applications a Pressure Regulator installed after the booster pump may be
required to restrict the outlet pressure and prevent damage to household
appliances & plumbing.
The International Residential Code states "A
means for controlling increased pressure caused by thermal expansion shall be
installed where ... a backflow prevention device, check valve or other
device is installed on a water supply system using storage water heating
equipment." (2903.4) Since most Booster Pump Systems and Pressure Regulators
incorporate a check valve, installation of an expansion tank is highly
recommended even if not required by local code.
