Product Specifications

General

Pump Category/Type

BWT075 Primary

Other Model BWT050 Primary

AC & DC Pumps: Duty Type

BWT075 Continuous

BWT050 Continuous

AC Pump: Motor Horsepower

BWT075 3/4 HP

BWT050 1/2 HP

What does AC Pump: Motor Horsepower mean?

A unit of power that indicates how much work a pump can perform when connected to a working wall outlet. The higher the horsepower, the more powerful the pump is, allowing it to move more fluid, overcome greater pressure, or lift fluid to higher elevations   

AC Pump: Motor Cooling

BWT075 Water-Cooled

BWT050 Water-Cooled

What does AC Pump: Motor Cooling mean?

How are pumps cooled? Most pumps are oil filled, using dielectric oil to draw heat from the motor and lubricate the bearings. That oil is in contact with the housing of the pump, which is cooled by the groundwater in the pit. Water-cooled motors have both more efficient motors and better bearings, which create less heat and no need for cooling oil. The motor is pressed directly against the housing, which is cooled by the groundwater in the pit. Note: A small amount (less than 1 oz.) of food-grade oil is in the bearings of a PSC motor for lubrication, not for cooling the pump.

AC Pump: Motor Type

BWT075 PSC

BWT050 PSC

What does AC Pump: Motor Type mean?

Basement Watchdog pumps incorporate advanced Permanent Split Capacitor (PSC) motors for energy efficiency and reliability vs. the older style shaded-pole motors.

AC Pump: Float Switch Type

BWT075 Dual, Micro-Reed Switches w/Cage and Controller

BWT050 Dual, Micro-Reed Switches w/Cage and Controller

What does AC Pump: Float Switch Type mean?

A float switch is the component of your sump system that turns on the pump. Most of our primary pumps use the super reliable Dual Float Switch to activate the pump.
