Product Specifications

General

Pump Category/Type

BWT050 Primary

Other Model BWT075 Primary

AC & DC Pumps: Duty Type

BWT050 Continuous

BWT075 Continuous

AC Pump: Motor Horsepower

BWT050 1/2 HP

BWT075 3/4 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

BWT050 Water-Cooled

BWT075 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

BWT050 PSC

BWT075 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.

Accolades

"Choice of the professional. Well designed and well built. The float design, and the fact that you can easily set the water level, and the fact you have a backup float, and that they are protected inside a cage—those are just some of the reasons I like this pump. And it is ½ HP, instead of ⅓ HP that competitors use."
