1. What triggers the DDP-60 to start?
The DDP-60 is equipped with a built-in pressure switch and an internal flow switch that activate the pump based on water consumption. The pump will start under the following conditions:
- When the pressure falls below the activation point of the pressure switch, or
- When the flow rate exceeds 0.7 GPM.
The specific activation point for each model can be found in the pump specifications.
2. What causes the DDP-60 to stop?
The flow switch automatically turns off the DDP-60 when the flow rate drops below 0.7 GPM. The pump will shut off within a few seconds after flow ceases (the DDP-60 is programmed to stop after 15 seconds). Additionally, the pump will deactivate in cases of dry-run or over-temperature alarms.
3. What is the function of the built-in pressure tank?
The pressure tank is factory pressurized to approximately 43 psi (with the pump pressure at zero). Its purpose is to reduce motor startup due to low flow demands or minor pipeline leaks.
4. How is a dry-run condition detected, and what protection is in place?
A dry-run condition occurs when the motor is running with a flow rate below 0.3 GPM and the pressure is less than the pressure switch setting. Protection features include:
- If the pump runs dry for 2 minutes, it will automatically shut off for 10 minutes before attempting to restart. If three restart attempts fail, the pump will rest for 1 hour before trying again. This cycle continues until normal water supply resumes.
If the pump cycles on and off repeatedly due to low flow (under 0.3 GPM), an air pocket in the system, air loss in the pressure tank, or a pipeline leak, it will operate for 8 seconds and stop for about 3 seconds. After 15 consecutive cycles, the pump will rest for 1 hour, then revert to protection mode until the issue is resolved.
Note: The pump can be reset at any time by unplugging it.
5. What is the maximum allowable inlet pressure for the DDP-60?
The maximum internal system pressure for the DDP-60 is 120 psi. The combined maximum inlet pressure and DDP-60 pressure must not exceed 120 psi. If the inlet pressure exceeds the built-in pressure switch activation point (factory default is 43 psi), the pressure switch will be unable to function properly, resulting in a loss of low-flow activation. In this scenario, only the flow switch will activate the DDP-60 at flow rates above 0.7 GPM.
