Product Description
Well Points: The Versatile Solution
Ideal for shallow aquifers where the water level needs to be lowered no more than 15 or 20 feet, Griffin well point systems allow you to pump anything from a few gallons per minute in fine sandy silts to thousands of gallons per minute in coarse sands and gravels. Our most versatile pre-drainage solution.

This system features well points spaced around an excavation and connected to a common header, which is in turn attached to one or more pumps. Deeper excavations will require multiple stages of well point systems due to the vacuum limitation of the pump.

When designing a well point system, Griffin will take into consideration a variety of factors, including:
• Physical layout
• Adjacent areas
• Soil conditions
• Permeability
• Amount of water to be pumped
• Depth to imperviousness
• Stratification
• Friction losses developed in the suction side system


The wellpoint dewatering system in comparison with other dewatering systems is:
Applicable in most type of soils
A flexible system
Effective and efficient
Easily to adapt depending on dewatering results achieved


More particularly in wellpoint drainage and dewatering, these pumps have come into widespread use because they perform their duty reliably under all conditions, with a minimum of attention and maintenance. Further, they are the most economical pumps for wellpoint drainage operations as they have an extremely high efficiency of about 92% resulting in a very low horse power motor requirement of only 7,5 kW. This means when operating with diesel engines you can comfortable use a one cylinder engine compared to a 3-cylinder of 22 Kw before.

Fuel saving per pump can go up to 27,500 liters per year per pump!!

Another main advantage in pumping water from dewatering wells is that they develop a pulsating vacuum, causing the water and/or air to be snatched out of the ground, as it were. Since this effect is beneficial to the stability of the bottom and slopes of the excavation, the reciprocating pump can indeed claim to be a universal pump suitable for horizontal drainage, for drainage from wells with free gravity inflow, or functioning on the vacuum principle. Thanks to their dual (duplex) form of construction, these pumps are characterized by very steady operation. A major advantage is that the capacity remains constant despite any increase in suction and/or delivery head. This is in marked contrast with centrifugal pumps, whose capacity shows a marked decrease if the suction head or delivery head is increased while the relatively high installed power remains viable. The piston pump is selfpriming and can handle therefor water and air without the need of an addional vacuum pump.Because of their smooth operation andslow running at a low rate of about 65 - 70 strokes per minute the pumps have by far the longest life-time for these wellpoint drainage applications. 

Wellpoints are jetted into the soil and each wellpoint is connected to a 4 inch header HDPE pipe to collect the water and pumped by pistonpumps creating a vacuum. The water is pumped away which creates lowering of the groundwater table.
