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.

delivery height can be no more than 15 times the intake fall height.
