Quick Overview

Add Items to Cart Add to Cart


Dankoff Solar Force Piston Pump draws water from a shallow well, spring, pond, river, or tank.

This surface pump can push water uphill and over long distances are at home, village, irrigation or livestock uses. It can use power directly from a photovoltaic array or from storage batteries to fill a storage tank or to pressurize water.

Ultra-efficientUses less power than any other pump in its range, starts pumping in low light conditions

EconomicalReduces power system costs by 25 to 75% compared to centrifugal or AC pumps

Solar-Direct ApplicationStarts pumping in low light conditions

Pressurizing ApplicationDC version is most efficient. AC version uses a low-surge permanent magnet motor that greatly reduces starting surge, inverter size, and wire size requirements (when compared to conventional AC pumps).

Rugged and Reliable
Proven design with a 20-year life expectancy, simple to maintain with common tools (5-10 year maintenance interval)

Good Tolerance for Dirt and Dry Run

Mechanical DriveAllows engine or hand-lever backup

Illustrated Instruction Manual

Voltages Available:

• 12, 24, 48 Volts DC - Note: PV-Direct full working voltage is typically 20% higher than nominal (example: 29 Volts DC for a 24 Volt DC system)
• 115 or 230 Volts AC, 50-60 Hz


2 years against defects in material and workmanship


• Cast iron body
• Brass cylinder and valve seats
• Leather cup piston seals
• Neoprene valve seals
• Oil-bath crankcase
• Gear (timing) belt drive on PV models
• Standard V-belt on B models
• Pressure relief valve
• Permanent magnet DC motor
• Surge tank included (not in photo)

Suction Capacity:

25 vertical feet (7.6m) at sea level. Subtract 1 foot for every 1000 feet elevation (1 meter for every 1,000 meters). Suction capacity may be further limited by intake pile friction. Intake piping should be minimum 1” (3010 & 3020 models) or minimum 1 ¼” (3040 models). For best reliability, place the pump as close to the water source as possible.


• Intake: 1 ¼” female pipe thread
• Outlet: 1” female pipe thread


• 22” L x 13” W x 16 “ H (56cm L x 33cm W x 41cm H)
• With Surge Tank (not shown in photo), total height 26” (60cm)
• Weight: Max 80 lbs (36kg) Shipped in 2 or 3 boxes

System Requirements:

• Solar-Direct Systems: Chart indicates power (w) required at the pump. The rated power of the PV array must exceed this number by 20% or more. A pump controller (linear current booster) is required for the pump to start and run in varying light conditions. A solar tracker may be used to increase daily yield (40-55% in summer).
• Pressurizing Systems: Battery power system, pressure switch, and pressure tank of minimum 60 gallon (230 liters) size (captive-air tank, available locally).
