High Performance - The BT4 horizontal booster pump is a low to medium capacity, high pressure, multi-stage unit. The BT4 can function as a multi-purpose high pressure pump, boosting water pressure from either city mains or private water systems. It is also ideal for applications that require more pressure than flow. Size ranges from 5 gpm to 25 gpm.

Cast Iron Features:
Designed for boosting water pressure from a variety of sources including municipal and private water systems.
Stainless steel discharge head on all models.
Cast iron motor bracket with a rugged support foot for horizontal or vertical mounting and a handle for portability of the unit.
1-inch suction and 1-inch discharge are the same across the entire line, simplifying installation and maintenance.
Built by Franklin Electric's patented (U.S. Patent 7,290,984) Tri-Seal floating stage system, for maximum efficiency, longevity and performance.
Assembled with the highest quality materials of construction, such as Celcon(*) for impellers, Noryl(*) for the diffusers and 300 series stainless steel for the hub, eye seals, shaft, and shell.
Easily serviced through a back pull-out design, which leaves all plumbing and the pump undisturbed in their original location.
Industry proven square flange motors.
Single-phase: 1/2 through 2 hp motors are dual voltage, set to run with either 115 V or 230 V incoming power, while 3 hp are 230 V only.
Shut-off pressures up to 270 psi, flow rates from 5 to 25 gpm, and temperatures up to 120 ºF / 49 ºC.

Stainless Steel Features:
Includes all of the cast iron features above plus:
Stainless steel models:
Viton(*) mechanical seal for corrosive fluids
Three-phase also available: 1/2 through 3 hp motors are dual voltage set to run with either 208-230 V or 460 V incoming power
Stainless steel motor bracket with a rugged support foot for horizontal or vertical mounting, and a handle for portability of the unit.
Designed for industrial applications.
