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.




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.

The TD5 solar DC pump can be used for most circulation pump applications without connection To the power grid. Highly efficient, the TD5 can be connected directly to a photovoltaic panel and is Characterized by its small size, high efficiency, and extreme low power consumption. The long Life brushless motor technology provides maintenance free and quiet service life. This Pump is perfect for single family home thermal solar systems or any circulation pump application Where conventional power is not available.
