Grundfos SQFlex Water Pump
WATER, WHEREVER, WHENEVER
With the advances in pump technology over recent years, areas that would previously have been considered uninhabitable or not supportive of life have become viable and attractive. The new Grudfos SQFlex remote water pumping system provides stable and low-maintenance pumping solutions for remote areas, and makes it easy to upgrade older, less reliable pump technology.
Potential SQFlex pump applications include:

SQFlex Pump Accessories

CU200
A user-friendly interface box that maintains two-way communication with the pump and monitors the operating conditions. Built-in diagnostics indicate faults and dry-running, display operating status power consumption and level switch input. |
$310.00 |
 |
IO 100
A very simple and easy-to-use system with cable interface. The IO 100 is designed for manual starting and stopping of the pump in an SQ Flex solar system. It also functions as a connection box joining all necessary cables.
IO 101
Acts as interface for powering back-up supplies, providing automatic change-over. For instance when changing from generator to solar energy, the solar panels automatically power the system as soon as the fuel tank runs dry. |
$89.00
$395.00 |
 |
Level Switch
Save energy as you save water. With a level switch inside the storage tank connected to the CU 200 control unit, the pump knows when the tank is full and shuts itself off. |

DC HOT WATER CIRCULATING PUMPS
High efficiency brass magnetic drive pumps for solar water heating, hydronic heating, and more. Very dependable long running continuous duty pumps. Great for hot tub filtration too. Models for 12 and 24 volt applications, PV Panel direct and Battery applications, Brushless and Brush types.
-
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.
Advantages
-
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.
Features
-
Magnetic drive These pumps feature seal-less magnetic coupling to the impeller. There is no seal friction, no seal wear, and no chance of seal leakage.
-
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)
El Sid Pumps by Ivan
The El Sid solar hot water circulating pump works beautifully with PV panels and its speed (flow rate) changes with the sun's brightness. This works well with solar water heating systems because when the sun is dim and not able to heat much water, the pump automatically slows down.

SURFACE PUMPS
The most economical DC water pumps are surface (non-submersible) pumps. They can reduce pumping energy consumption by half or more, compared to conventional AC pumps.
Surface pumps can pull the water up to 20 feet (suction capacity) and lift or push up to 900 feet. Our pumps have a wide range of applications and can provide as little as 0.5 gallons per minute and up to 70 gallons per minute. Surface pumps must be protected from weather and freezing. |
