   DANKOFF SOLAR PUMPS-SUNCENTRIC 7212 DC SURFACE PUMP

SUNCENTRIC SERIES CENTRIFUGAL PUMPS PV DIRECT & BATTERY BASED MODELS

The SunCentric uses solar-electric power to pump as much as 50,000 gallons (200 m³) per day from shallow water sources.

Applications include irrigation, live stock, domestic water, pond management, water tr eatment, solar water heating, hydronic space heating and fire protection. These pumps have been in worldwide use since 1989. They can be used without batteries. Maximum suction lift is 10 vertical feet (3 m).

PV Direct Applications

  • A PV-direct system uses water storage instead of batteries. This is the simplest and most reliable system, and is easy to transport.
  • No electronic controls are required
  • A solar tracker (optional) will help to maintain optimum flow through the entire solar day
  • Storage of 3-7 days' water demand is recommended
  • Optimum for circulation of solar-heated water
  • Sump Pump

Battery Based Applications

  • A battery system is best where there is need for constant pressure or pressure on demand, or where a tank is not feasible, or where a battery system is required for other power applications.
  • Batteries can be charged by any power source

To choose the best pump for your application, select the appropriate chart of "PV Array-Direct Applications" or "Battery Applications".

  • Total Dynamic Head = Vertical distance from surface of the water source to the discharge or top of storage tank + pipe friction losses.
  • Use solid line grid for English units. Use broken line grid for metric units.
  • Locate the coordinates for the required head and flow.
  • Find the pump curve that is nearest to that point.
  • If there is more than one curve to chose from, compare the power requirements.
  • For PV-Direct systems, array sizing (watts) is critical. DO NOT undersize the array. ** For oversizing the array, you should have no more than 145% of the minimum pv watts required.

Suction Capacity

  • Suction limit is 10 vertical feet (3 m) at sea level-subtract 1 foot for every 1000 ft. elevation (1 m per km).
  • For best reliability, place the pump low and close to the water source to minimize or eliminate suction.

Pump Placement

  • Place the pump close to the water source to minimize suction lift. This will minimize the possibility of cavitation which causes excessive wear and loss of performance.
  • Horizontal position: Place outlet at the top. It can be rotated to face horizontally or vertically upward.
  • Vertical position: Place motor on top.
  • Pump must be sheltered from rain and direct sunlight.

Wire and Pipe Requirements

  • Intake pipe: Pipe should be as direct and short as possible. Avoid any high point that can trap an air pocket.
  • Refer to a pipe sizing chart (included with the pump instructions). Pipe may need to be larger than the pump ports. Undersized pipe will greatly decrease pump performance.
  • Refer to a low voltage wire sizing chart. Size the wire for less than 3% voltage drop. Undersized wire will greatly decrease pump performance.
