The Flex-frame motors are usually labeled as 48Y, but will have the distinct pedestal at its base. The Flex is unique because it uses four thin partially threaded screws (known as thru bolts) that are slid the length of the motor through the back end and screwed into the seal plate.
What does 48 frame mean on a motor?
The main difference between a 48 frame and a 56 frame hot tub pump is that the 48 frame has a smaller motor housing and so the 4 through bolts that fasten the wet end to the motor are closer together on the smaller motor.
What is the difference between 48Y and 56Y frame?
What is the difference between 48Y & 56Y? Both have the same exact size square flange. The 56Y motor body diameter is 1/2″ larger than 48Y, so the 48Y usually includes a 1/2″ rubber spacer if required when mounting. Body diameter is the only difference, they can be inter-changed.
Can I replace a 48 frame spa pump with a 56 frame?
Almost all spa pumps are manufactured in one of two standard frame sizes: 48-Frame and 56-Frame. If you want to replace your wet end or your motor, you should use an equivalent of the same size, so that the mounting holes between the motor and the wet end align.
How do I choose a motor frame size?
Just divide the first two digits by four. Thus, a 405 frame (original, U frame, or T frame) has a shaft height of 40 divided by 4, or 10 in. Although no direct inch measurement relates to it, the third digit of three-digit frame sizes is an indication of the motor body’s length.
What does 56h frame mean?
H — Used on some 56 frame motors, “H” indicates that the base is suitable for mounting in either 56, 143T, or 145T mounting dimensions.
What is sizing of motor?
Motor Sizing Motor sizing refers to the process of picking the correct motor for a given load. It sis important to size a motor correctly because: a. If a motor is too small for an application it may not have sufficient torque to start the load and run it up to the correct speed.
What does frame size mean on a motor?
The frame size of a motor defines its mechanical interface to attached actuators. Motors of the same frame size can have different power, torque etc. but feature the same geometrical properties. The length of the motor housing is not affected by the frame size.
Can I replace my pool pump myself?
A professional electrician will be needed to disconnect the wiring before a pump can be removed. Once a new pump is installed, an electrician will again be necessary to reconnect the wires to the new pump.

What does C face motor mean?
C-Face Design:
Having a flat surface machined onto one side allows for direct-coupling with equipment while the weight of the motor is cantilevered with the help of a heavy duty flange. Of course, this method is not useful for large motors and is rare in HP ranges over 20HP.
What does C mean on motor frame?

What is au frame motor?
The “U” frame motors were designed for use with Class A insulation, which has a rating of 105° C. The motor designs were such that the capability would be used at the hottest spot within the motor. “T” frame motor designs are based on utilizing Class B insulation with a temperature rating of 130° C.
What is pump frame?
