PIPING
PIPING GUIDELINES
- Use larger piping to increase plumbing efficiency, ensuring that the suction side pipe diameter is equal to or larger than that of the return line to facilitate optimal flow.
- Keep the suction side piping as short as possible to enhance pump performance.
- Maintain a straight section of pipe on the suction line that is at least five times the pipe's diameter before the pump's inlet.
- Example: For a 2.5-inch diameter pipe, ensure at least 12.5 inches of straight piping before the suction port. This setup improves priming speed and extends the lifespan of the pump by reducing turbulence.
Figure 2 shows optimal piping layout, emphasizing a straight pipe section at least five times the suction pipe's diameter before the pump inlet to minimize turbulence and improve priming.
FITTINGS AND VALVES GUIDELINES
- To reduce turbulence and prevent cavitation, avoid placing 90° elbows directly at the pump's suction port.
- For flooded suction systems, install gate valves on both the suction and discharge pipes to allow for easy isolation during maintenance.
- Position the suction gate valve at least five times the suction pipe's diameter away from the pump to prevent interference with flow dynamics.
- Install a check valve on the discharge line, especially if the plumbing has a significant rise after the pump, to prevent water backflow and help maintain consistent pump performance.
- When plumbing two pumps in parallel, install check valves on each pump's discharge line to prevent reverse rotation of the impeller and motor, which can occur if one pump is running while the other is off or during fluctuations in flow.
