1. Introduction Thank you for choosing a quality product manufactured by Texmo Industries. We request you to read this manual thoroughly so as to ensure that the product you have purchased will be operated correctly. This manual is intended to provide you with information on your product and information on installation and operation.
5. Information about your pump The discharge of a pump depends on the static suction facilities and will give trouble-free performance lift. During summer, the static suction lift increases if properly installed and maintained. These are due to drop in water levels, and this results in reduced compact pumping systems with the pump and motor discharge.
