The factory pressure-check valves should be sufficient when two pump outlets are connected in parallel. However, this may depend on the specific application. We recommend consulting a hydraulic specialist regarding your application to ensure the setup will work properly.

Are the factory pressure check valves sufficient when the two pump outlets are paralleled.

Do the return-port plug conversion leaves pump flow continuously available at P whenever the motor runs?
1 answer-
NorTracExpert12· 4 days ago
The return port conversion converts the power unit to be a Pressure & Tank unit. This means the unit supplies fluid pressure to a valve block and returns fluid to the tank. As long as your system does not require more volume than the tank holds, this unit will provide fluid to the system throughout the cycle.

“Can 2 model 53451 power units with separate 16-gal reservoirs be operated with their pressure outputs paralleled through check valves? If so, what is the approved method for balancing/equalizing the two reservoirs when they share a common return circuit?
1 answer-
NorTracExpert12· 5 days ago
Each unit has its own check valve. To equalize the fluid levels between the reservoirs, connect the reservoirs using the lowest available port on the power unit’s reservoir.
For the additional reservoir, position the connection port approximately 1 inch above the bottom of the reservoir. This helps prevent particles or debris from being transferred between the reservoirs.
Keep in mind that modifications like this will void the warranty and should only be done at the user's discretion.
