W Lim pumps are all assembled at the W Lim manufacturing plant in Mira Loma California. Each pump is tested for 10 to 15 minutes prior to boxing and shipping.

All W Lim pumps now offer improved features such as:

  • An additional swing seal located on the motor shaft to repel water away from the motor.
  • Another benifit to the increased value is the enclosed bearing to keep water damage reduced in case of external flooding to the motor.
  • Stronger enclosed housing that also provides water protection from rain.

As always when researching products and compareing brands, you get what you pay for! W Lim pumps deliver the flow rates advertised and are better engineered than many other brands... Third Party testing has proven this and the results were posted in the Oct./Nov. 2007 issue of Koi Nations magazine.
