Topsflo TD5 Vari-Speed 25W 25PV Solar DC Circulation Pump

An Excellant DC circulator pump

Very efficient, Very durable. Great for solar systems & DC heating systems.

The TD5 pump can be powered from a 12V source, or directly from a PV Solar Panel. 

Not for direct AC operation. Can be powered by a 24.0V 2A AC to DC converter.

In Solar applications having the pump powered directly from a PV panel, assures that the pump power is controlled by the intensity of the sun. 

In some cases this can eliminate the need for controllers, thermostats, and sensors.

Differential controllers, DC Converters, zone valves, Heating control boxes & other equipment available for use with the DC circulators

Very energy efficient

Areas of Use:

• Solar Water Heating Systems
• Hot Water Circulation
• Radiant Floor Heating
• Heat Transfer Applications
• 12V Operated Cooling Systems
• Liquid Transfer 
• General Purpose Pumping

Ideal for circulation pump applications: 

1. Hot water circulating system; 

2. Remote area fluid handling 

3. Process temperature control 

4. Water or oil cooling circulating system 

5. Circulating systems for homes, RV's and boats 

6. Fuel cell systems 

7. Oxygen generating systems 

8. Aquariums and ponds and so on.

Designed to perform well with a variety of fluids other than just water. Excellent tolerance with oils, fuels, lubricants and most mineral acids.

Warning: Do not run without fluid

Two or more pumps can be parrelled to acheive even higher flow rate, or plumbed in series to increase head pressure capability.

We have used this lineup of DC pumps on our solar systems for the last seven years now. They have proven to be even more durable than the Laing and the El-Sid DC circulator pumps... especially in open-loop systems where more dirt, rust particles or air bubbles can get into the lines despite of good plumbing system design.
