air supply is maintained.
B. Check vacuum at the pump suction. Capacity is reduced as vacuum increases.
Reduced flow rate due to starved suction will be evident when cycle rate can be varied
without change in capacity. This condition will be more prevalent when pumping viscous
liquids. When pumping thick, heavy materials the suction line must be kept as large in
diameter and as short as possible, to keep suction loss minimal.
C. Low flow rate and slow cycling rate indicate restricted flow through the discharge line.
Low flow rate and fast cycling rate indicate restriction in the suction line or air leakage
into suction.
D. Unstable cycling indicates improper check valve seating on one chamber. This
condition is confirmed when unstable cycling repeats consistently on alternate exhausts.
Cycling that is not consistently unstable may indicate partial exhaust restriction due
to freezing and thawing of exhaust air. Use of an anti-freeze lubricant in an air line
lubricator should solve this problem.
