Solar 17V dc miniature sun pump for tankless water heater
Solar 17V dc miniature sun pump for tankless water heater
TD5 is the specialized solar pump series newly developed based on our TS5 pump.
TOPSFLO TD5 pump is currently the world's only all-stainless steel solar hot water circulating pump, made of food grade stainless steel, very safe and reliable, always protect your family's health, food grade stainless steel is healthy and safe metal to our people, acid resistant, no dangerous element exudation, the medical equipment and food machinery widely used is the best example.
1. Directly connects to photovoltaic panel, start-up power requires less than 2 Watt
2. Ideal 5W, 10W, 15W, 25W power consumption optional for different sizes SWH systems
3. The exclusive food grade stainless steel solar DC hot water pump,keep far away Plumb danger more safe, protect your families' health
4. Operates on safe DC power, you will not expose yourself to hazardous grid power voltage
5. High efficient ECM brushless DC motor, ideal long life time 30000 hours
6. Advanced magnetic drive technology for static-seal,without any leakage for ever
7. Can run with hot water (230° F) and at high pressure(145 Psi)
TD5 is the most advanced pump we developed for solar hot water heating system, which is similar to the SID & Laing D5 pumps from US. It's max flow rate and max water head reach 25L/Min and 4M. -Besides, it has the same function as Laing D5 in realizing different performance from 5-20W via the knob on pump bottom for Changing flow rate conveniently. More importantly, compared with Laing D5 it is very prominent in the following points:
1. Endure high temperature till 110°C;
2. Endure high system pressure 10bar;
3. Fully stainless steel pump head and chamber;
4. More competitive prices than Laing D5 but better overall performance.
Advantages over solar pumps from SID and Laing D5
many of our clients also reflected application problems by using SID and Laing-D5 pumps, such as tempreature, MPPT max efficiency and so on. But they are very satisfied with ours till now since transition. Our TS5&TD5 solar pumps are developed by studying SID and Laing-D5 pumps first,
1. Motor
2. MPPT functions
Then optimize their weakness. For example, there exists tempreature issue due to spherical motor for Laing D5 pumps, and SID pumps do not have MPPT functions. Generally, our solar pumps have comprehend all advantages and optimize the advantages for supporting solar system at its max performance, and have been tested and applied in the market for a long time with nice feedback. I believe topsflo will be a great choice for you.
No. | Weakness | Improvement |
1, Motor | tempreature issue due to spherical motor for Laing D5 pumps | High efficiency ECM brushless DC motor, reach clients’ requirements in long lifetime and over all performance. |
2, MPPT function | SID pumps do not have MPPT functions | TD5 with MPPT function, can realize four powers, 5W, 10W, 15W, 25W automatically wuth hiest efficieny. |
3, Structure&Design | SID&Laing D5 | More reasonable and nicer-looking |
