    Default Xtra Solenoids On Diverter Pump?

    Does anyone know why the hydraulic diverter pumps have the extra set of external solenoids compared to the standard "Bennett" pumps? You know my next question, will a standard Bennett pump work?

    Thanks.

    Bennett trim tabs use a single acting cylinder (pressure to extend and a spring makes them retract). This is acceptable because the water pressure is always trying to force them up to thier collapsed position.

    Place uses a double acting cylinder (pressure to both extend and to retract) to accurately control the diverter trim setting. In this case you need the positive control both extending and retracting because there is no constant force to help control the position of the diverter.

    Thanks to all that replied. Now, can I buy the extra solenoids to put on my standard Bennett pump?

    Thumbs up

    NO.
    The two pumps do not work the same. You can make a simple circuit to make this happen. I'm a hydraulic specialist, I can make you one. If interested send me $1,800.00 and I'll get right on it.

    Pump is energized, turns one way only. Two valves open, one valve goes to the cylinder port A, (rod end) the other valve comes from the cylinder port B, (cap end) nozzle down.
    The valves open, one goes to cylinder port B, the other comes from cylinder port A, nozzle up.

    You could use your Bennett pump to supply a manifold with the four solenoid valves. Then use diodes and trim switches to energize the coils.
