Q: I have a Laing hot tub pump. Model #sm-1212-nhw-19, serial No.1012485, Part # 63059. I see you have a sm-1212-nhw-21 is that the same pump? If not can I get a price on a rebuild kit and the complete pump? RPM 3450, watt 140, amp 0.6, 230 V,1p,60hz.
A: The SM-1212-NHW-19 used to be for both the 3/4" barb and the 1" barb pumps. To simplify things they turned the SM-1212-NHW-19 into the SM-1212-NH-21 or the SM-1212-NH-26 depending on the connection size.
So if you have 1" tube then you need the SM-1212-NH-21 at the link below:
If you have 3/4" tube you need the SM-1212-NH-26 at the link below:
Q: I had a "W" in my original Laing number and the replacement you reccomended does not. What is the difference?
A: The "W' stood for "with cord". Since there are a variety of cords it is best to simply reuse the cord from your original pump.
