Pumpjack Connections
1.
Remove power to the pumpjack and wait for the
pumpjack to stop moving.
2.
Attach a cable (N) to the walking beam (P) using a
beam clamp (R) or other connection method (both
user-supplied).
•
Place the beam clamp (R) on the walking beam
(P) where the vertical travel is, at most, 21 in.
(53.34 cm), which is the maximum travel of the
G-Chem pump’s lever arm.
3.
Position the G-Chem pump (A) on the pumpjack
base (M) so that the walking beam (P) provides a
straight upward pull as it rises.
•
The lever arm (122) must be able to travel 6 in.
below the base of the G-Chem pump (A) to
achieve maximum flow.
4.
Securely clamp or bolt the G-Chem pump (A) to the
pumpjack base (M) using the pump’s supplied
base (112).
•
The G-Chem pump (A) is shipped with the sup-
plied base (112) already attached.
5.
Connect the lever arm (122) to the walking beam
(P) by routing the end of the cable (N) through the
eye bolt (8) on the supplied swivel block (B).
6.
Ensure there is no slack in the cable (R) when the
G-Chem pump (A) is maximum stroke (setting “1”
on the lever arm (122) and “Full” on the stroke
adjust). Refer to
Adjust the Pump Stroke
