Hot Water Pumps
High efficiency brass magnetic drive pumps for solar water heating, hydronic heating, and more. Very dependable long running continuous duty pumps. We've used them around here for years without a problem. Great for hot tub filtration too. Models for 12 and 24 volt applications, PV Panel direct and Battery applications, Brushless and Brush types.
DC HOT WATER CIRCULATING PUMPS
- PV powered circulation for solar heating closed-loop using water or glycol solution
- Hydronic radiant floor space heating for off-grid or uninterruptible battery backup
- Instant hot water distribution (DC controllers also available)
- Pond management, water treatment, fountains, aeration, etc.
For solar water heating (PV-direct)
- Use a small, inexpensive PV module (photovoltaic panel) to power the pump. No electronic controls are used. There is no wiring to the building's electric system.
- Sun-synchronous operation: the pump speed varies with the sunlight, closely corresponding to the available heat in the collector-natural automation!
- This principle has proven highly reliable in solar water heaters since the early 1980's.
For hydronic heating (using battery)
- Power requirement is less than half that of conventional AC pumps powered by inverter.
- Additional energy savings can be realized by using individual zone pumps instead of a single pump with electric zone valves. This method can reduce power consumption by 75%.
- Energy saving greatly reduces the size and cost of the power system required.
- These pumps feature seal-less magnetic coupling to the impeller. There is no seal friction, no seal wear, and no chance of seal leakage.
- Ivan and Hartell pumps use brushless (electronically commutated) motors that are maintenance-free.
- March pumps use brush-type motors with typical brush life of 2-5 years. Brushes are easily replaceable without removing the pump.
Over current Protection
- PV-direct: No fuse is required, unless PV module is oversized beyond 1.5X recommended size.
- Battery system: Fuse is required. See watts on chart. Fuse size = watts/volts X 1.5 to 2.
Temperature and Pressure Limits
- Maximum: 250°F (120°C) at 150 PSI (10 bar)
- One year against defects in materials and workmanship.
