This pump has a plastic impeller, but it is also available with a cast iron impeller (part 267-0057).
The purpose of the variable level float switch is to increase the capacity or run time for the pump when it is operating. Instead of having a non-adjustable ON and OFF point like the M267. The variable level float allows you to adjust the ON and OFF point to accommodate the volume of water/sewage to be pumped out of the system. The manufacturer recommends a BN/BE model when a pump is going to be used in a residential septic system. The pumps are usually in 1000 gallon tank or larger so it would require a larger volume of water to be pump out and typically the float would be adjusted to the pump off, leaving the pump fully submersed in the water.
The variable level float switch is attached to the end of a 15' cord. Typical application is to mount the cord to the discharge pipe in a septic tank or other holding tank. The float can be installed at any height in the tank and the length from the attachment point sets the turn on and turn off levels for the pump. So therefore it is "variable". If you search a float switch similar to Zoeller 10-0034, you can get an idea of how they are installed and if you need a "variable switch. I think the regular float switch you are referring to is one that is mounted directly on the pump? If that is what you are trying to replace, then you do not want the variable switch.
