All variations of the company's Series 500 have been designed to handle the operating conditions present in all water cooling tower applications. Features include the Variable Oil By-pass stroke adjustment. The valve checks have extra time to seat, even in heavy liquids, because they are idle during the bypass portion of the suction and discharge strokes. The cartridges can be removed for cleaning without disturbing the pump piping.
