Folk Hydraulic Ram Pumps
These rams are made from cast aluminum alloy and stainless steel. They
can pump a maximum of 500 feet and operate from a fall of 50 feet or less.
There are six models to choose from. The amount of water each size can
pump is determined by the inlet flow, inlet fall and delivery height.
Each size ram has a range of inlet flow it can operate from. If you have
more flow, there is no problem, but if you have less flow, the ram will
not operate.
Ram Info and Formula
As little as 2 feet fall from the water source to the pump at a flow rate
of 1 to 3 gpm can provide up to 10 feet of vertical lift per foot of fall.
For example, if you need to pump water 30 feet uphill, then you will require
a minimum fall of 3 feet (a 10 to 1 ratio). However, in order to achieve
a greater output of water at this lift, it is better to keep the fall-lift
ratio as small as practical. We can achieve a 5 to 1 ratio by increasing
the fall of the water to 6 feet (6 x 5 = 30). The actual output of a ram
can be calculated with this formula: V x F x 0.5 / E = D, where V is the
available water flow in GPM, F is the vertical fall from the water source
to the ram, E is the vertical lift from the ram to the top of the delivery
pipe and D is the water delivered in GPM.
Note: The drive pipe must be 3 to 5 times as long as the vertical inlet
fall for proper operation. On Folk rams, steel pipe must be used for the
drop pipe.
