Page 14: Piping Checklist
4 Installation Guideline Explanation/comment Keep the pump as close to the liquid source as practically This minimizes the friction loss and keeps the suction possible. piping as short as possible. If the pump is not on a closed system, locate the pump so that the fewest number of bends or elbows in the suction pipe are needed. -
Page 15: Typical Pump Installation
4 Installation Check Explanation/comment Checked For pumps with flanges, check that the bolt holes in — the pump flanges match the bolt holes in the pipe flanges. For pumps mounted in vertical piping with the motor This prevents strain on the pump parts and in the horizontal position, check that adequate piping. - Page 16 4 Installation In many installations, the piping is installed near the ceiling with the pump located close to the floor for ease of maintenance. Pumps with up to 4 inch nozzles and up to 286 NEMA frame motors can be installed in this configuration with pipe hangers adequate to carry the loads from the pump, piping and piping accessories.
