12V DC Circulator Pump Variable Speed Solar Hot Water 12V Topsflo TD5 25PV 25W

Description

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.

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.
