Description
This integrated pump assembly serves as a direct Wavemaster 4000 substitute for Watkins systems, part number 37334. Operating at 115V with dual speed capability, this 48 frame unit features 2" x 2" connections where threaded ports span approximately 3" across. Important: This unit draws 11.0A—when installing on systems with standard wall outlets, verify your electrical capacity can handle this amperage alongside your heating element to prevent circuit overload. Always confirm amp ratings match your original equipment when selecting 115V replacement pumps to avoid electrical issues.
