BT4 Series Horizontal Multi-Stage Booster Pump

Brand: Franklin Electric Co, Inc.

Add Product to My Catalog

The BT4 horizontal booster pump is a low to medium capacity, high pressure, multi-stage unit.

The BT4 booster pump 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 45 gpm.

Features

5-25 GPM BT4 Series

Cast Iron:

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

Assembled with the highest quality materials of construction, such as Acetal for impellers,
Modified PPO 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 °F / 49 °C

Stainless Steel:

Includes all of the cast iron features above plus:
Modified PPO 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.
