water pumps
Jewell Drilling Services use a variety of different water pumps and will be efficient in choosing the right one for you fitting all of your requirements.
What is the Pump Protector – DRP?
The Pump Protector - DRP is an innovative electronic device that guarantees optimal protection of the submerged pump from dry running. Additionally, it also protects the motor from burning out in case of it repeatedly starting and stopping.
Where is the DRP installed and how does it work?
The DRP is ready for use, integrated into the connection cable and doesn't need any further installation. In case of water shortage, the DRP will stop the pump from running immediately, when the water drops below the DRP and the pump restarts automatically a short time after the water will then rise above the DRP to allow the water to then flow into the borehole. In contrast to traditional solutions, no additional cables, sensors or control boxes are required. The DRP device has been developed and tested to make the submerged pump function autonomously in conditions of water shortage.
We are able to provide a selection of ZDS 4” Pumps
ZDS submersible pumps are known for their unparalleled reliability.
They offer a unique combination of efficiency, motor burn out protection, easy maintenance and high resistance to abrasives, including that pernicious, ubiquitous enemy of all pumps – sand.
In case of repeated starting and stopping of the pump, such as when the air in a pressure tank is low or the membrane is damaged, the DRP registers the frequent starts and stops and will automatically stop the motor from burning out. The DRP may be reset simply by disconnecting the power supply.
What are the technical limitations?
NOW the Pump Protector - DRP is available for Franklin motors single-phase as well as three-phase.
- The blue DRP for single-phase use has a permissible range of 220-240V at frequency 50/60 Hz. To manage the inductive load of a single-phase motor, the maximum motor power is limited to 2.2 kW.
- The red DRP for three-phase has a permissible range of 220-240V at frequency 50/60 Hz maximum motor power is limited to 2,2 kW. For 380V-415V motors at frequency 50/60 Hz maximum motor power is limited to 4 kW.
