Hydraulic Lines
Supply Line (L): Connect a 1/2 in. minimum ID to the
3/4–16 UNF–2a, 37 male flare inlet of the reciproca-
tor.
Return line (D): Connect a 5/8 in. minimum ID to the
7/8–14 UNF–2a, 37 male flare outlet of the reciproca-
tor.
On the hydraulic supply line (L), install the following
accessories:
A shutoff valve (E) to isolate the system for servic-
ing.
A fluid pressure gauge (F) to monitor the hydraulic
oil pressure to the reciprocator and avoid overpres-
surizing the reciprocator or displacement pump
A pressure- and temperature-compensated flow
control valve (G) to prevent the reciprocator from
running too fast.
A pressure-reducing valve (H) with a drain line (K)
running directly into the hydraulic return line.
An accumulator (J) to reduce the hammering effect
caused by the reciprocator reversing direction.
On the hydraulic return line (D), install a shutoff valve
(R) for isolating the reciprocator for servicing.
WARNING
To reduce the risk of serious bodily injury, including
fluid injection, your system must include a drain
valve installed near the pump fluid outlet to help
relieve fluid pressure in the displacement pump and
hoses when shutting off the pump. See Fig. 2.
Install a fluid drain valve (B) and a grounded dispense
hose (A) to the 3/8 npt fluid outlet on the displacement
pump. Connect a suction hose to the 3/4 npt pump
fluid intake. See Fig. 2.
