Models: JDP1000, JDP3500, JDP6000, JDP10000, JDP18000 Key benefits Precise, energyefficient water circulation: Frequency conversion (variablespeed) control lets you set the exact flow you need, reducing energy use and avoiding overpumping. Safe lowvoltage operation: Designed for DC 24V systems for safer installation and reduced electrical risk compared with mainsvoltage pumps. Versatile submersible design: Built to operate submerged for reliable, maintenancefriendly pumping in a variety of installations. Readytouse option: JDP1000 ships with a UK adapter plug for easy connection where required. What this pump solves Eliminates manual flow balancing by providing adjustable, stable flow rates through frequency conversion control. Reduces overheating and wear in closedloop and circulating systems by matching pump speed to demand. Simplifies installation in lowvoltage environments and locations where safe, submersible operation is required. Core features and attributes Functionality: Frequency conversion (variablespeed) circulating water pump suitable for continuous circulation and recirculation tasks. Adjustable flow control for precise regulation. Power and safety: Designed for DC 24V supply to minimize electrical risk while providing dependable pumping performance. Form factor: Submersible pump design for direct placement in reservoirs, sumps, tanks, or water features. Models and selection: Available in multiple models (JDP1000, JDP3500, JDP6000, JDP10000, JDP18000) so you can choose capacity and performance appropriate for your system. Included accessory: JDP1000 includes a UK adapter plug to support immediate use with UKstyle outlets. Performance notes Frequency conversion control provides smooth, stepless adjustment of flow and can improve system stability by matching output to demand. Submersible operation supports quieter running and reduces the need for external plumbing compared with inline units. DC 24V compatibility makes the pump suitable for systems where lowvoltage safety and compatibility are priorities. Use cases Aquariums and aquaculture: Maintain steady circulation, filtration, and oxygenation with adjustable flow to match tank size and species requirements. Hydroponics and plant cultivation: Provide reliable nutrient solution circulation and adjustments for different growth stages or crop types. Small cooling loops and water features: Circulate coolant or fountain water in compact cooling systems, desktop fountains, or decorative water features where adjustable flow and submersible mounting are needed. Installation and operation tips Verify system voltage and connector compatibility before installation; JDP1000 includes a UK adapter plug for direct UK connections. Install submerged in the cleanest practical location within the tank or reservoir and avoid running the pump dry. Use the frequency conversion control to dial in the minimum flow for your application to extend pump life and minimize energy use. Follow basic maintenance: periodic cleaning of intake and impeller area to prevent blockage and maintain performance. Ordering and model selection Choose the model (JDP1000, JDP3500, JDP6000, JDP10000, or JDP18000) based on the circulation capacity and head requirement of your system. The JDP1000 model is supplied with a UK adapter plug. If you need help selecting the right JDP model for your application, compare desired flow and head requirements with available model options to match performance to system needs.
