Economical

Reduces power system cost by 25-75% compared to centrifugal or AC pumps

Rugged and Reliable

Proven design with a 20 year life expectancy

Simple to Maintain
Dirt-tolerant
Dry Run-tolerant
Easy-to-install
High lift and Flow

Suction Capacity

7.6m at sea level. Subtract 1m for every 1000m elevation. Suction capacity may be further limited by intake pipe friction or gases in water. For best reliability, place the pump as close to the water source as possible.

Construction

• Multiple diaphragm industrial design
• Cast aluminium pump body
• Neoprene diaphragms backed by pistons
• Non-toxic oil-filled crankcase
• Massive ball bearings
• Permanent Magnet DC Motor
• Gear (timing) belt drive
• Pressure relief valve included

Power System Requirements

  • Solar (PV) array: Chart indicates power (W) required at the pump. For solar array-direct (non-battery) systems, the rated power of the PV array must exceed the pump watts by 25% or more
  • 120 V models: Use 10 x 12 V or 5 x 24 V modules in series
  • Linear Current Booster (pump controller) is required to facilitate starting and to prevent stalling in low-light
    conditions
  • Solar tracker: Optional, to increase daily yield (typically 30%)

Accessories

  • 31.2 mm Foor Valve (item #DSP-11044) if pump is placed higher than water source
  • Float Switch (Item #DSP-11003) for remote shur-off of the pump when tank fills
  • Diaphragm and Oil Kit (Item #DSP-08503): Supplies for regular preventive maintenance
  • Long-term Parts Kit: (Item #DSP-08504) Three Diaphragm and Oil Kits, plus a gearbelt and motor brush
    set
