The HySecurity MX3682 is a 3.1 GPM biodegradable hydraulic pump pack for select HySecurity / Nice HySecurity StrongArm M30 and StrongArm M50 barrier arm applications with 20-24 ft clear openings. This pump pack is used where the current HySecurity parts diagram or service information calls for the biodegradable replacement pump pack version.
Public product information identifies MX3682 as a 60Hz pump pack with biodegradable hydraulic fluid for StrongArm M30/M50, 20-24 ft clear opening. Common listings also note that it ships with two 3/8 inch hoses, 1/4 inch quick disconnects for older M30/M50 systems, and a motor coupler. Always confirm current package contents before ordering.
The MX3682 pump pack provides hydraulic flow for compatible StrongArm M30/M50 barrier arm systems using biodegradable hydraulic fluid. In a properly operating hydraulic barrier, the pump pack works with the motor, manifold, valves, reservoir, hoses, fittings, cylinder assembly, and arm hardware to raise and lower the barrier arm in a controlled manner.
The 3.1 GPM flow rating, 20-24 ft clear-opening designation, and biodegradable-fluid configuration are all important. Installing the wrong pump pack can affect arm movement, hydraulic pressure behavior, cycle speed, hold control, and long-term system reliability.
This pump pack may be used with the following applications where the current HySecurity parts diagram confirms MX3682:
Important: Do not assume MX3682 fits every StrongArm M30/M50 unit. This part is associated with 20-24 ft powered M30/M50 applications using biodegradable hydraulic fluid. Shorter clear openings, standard-fluid systems, no-power NP models, and other StrongArm families may use different pump packs.
StrongArm M30/M50 pump packs are configuration-specific. Clear opening, flow rate, hydraulic fluid type, 60Hz power configuration, hose ends, quick disconnects, motor coupler, pump arrangement, and manifold connection all matter.
| Part Number | Common Description | Interchangeability Note |
|---|---|---|
| MX3682 | 3.1 GPM biodegradable pump pack for StrongArm M30/M50, 20-24 ft | Correct where MX3682 is listed for the 20-24 ft biodegradable powered M30/M50 configuration |
| MX3613 | 3.1 GPM standard-fluid pump pack for StrongArm M30/M50, 20-24 ft | Same clear-opening and flow group, but not the biodegradable-fluid version |
| MX3614 | 4.0 GPM standard-fluid pump pack for StrongArm M30/M50, 12-18 ft | Different flow and clear-opening configuration |
| MX3688-01 | 3.1 GPM biodegradable pump pack for StrongArm M30/M50 NP no-power, 20-24 ft | No-power NP version; not the same powered pump pack as MX3682 |
| MX3688-02 | 4.0 GPM biodegradable pump pack for StrongArm M30/M50 NP no-power, 12-18 ft | No-power and shorter-opening version; not the same part |
The MX3682 pump pack is tied to StrongArm M30/M50 applications with 20-24 ft clear openings and biodegradable hydraulic fluid. Do not select this pump pack based only on the StrongArm model name. The clear opening, powered versus no-power configuration, hydraulic fluid type, pump flow rate, hose style, quick disconnects, motor coupler, manifold, and hydraulic circuit must match.
Biodegradable hydraulic fluid should not be mixed casually with standard hydraulic fluid. If the system has been serviced before, verify the current fluid type, reservoir condition, hose condition, and maintenance history before ordering this biodegradable pump pack. If the operator is in a cold climate, confirm that biodegradable fluid is suitable for the site conditions.
If the barrier arm is slow, weak, noisy, leaking, drifting, or not moving, do not assume the pump pack is the only failed part. Check the motor, motor coupler, reservoir, hydraulic fluid, hoses, fittings, manifold, brake valve, relief valve, flow controls, cylinder assembly, pins, bearings, and arm hardware before replacing the pump pack.

Before replacing the MX3682 pump pack, inspect the complete StrongArm M30/M50 hydraulic system. A slow, weak, noisy, or non-moving barrier arm can be caused by pump wear, but it can also be caused by low hydraulic fluid, contaminated fluid, air in the system, hose restrictions, leaking fittings, valve issues, a damaged motor coupler, motor problems, cylinder bypass, or mechanical binding in the arm assembly.
Fluid type matters. MX3682 is the biodegradable-fluid version. If the operator was previously serviced with standard hydraulic fluid, confirm the current fluid type and whether the system requires cleaning, draining, or related fluid service before installing the replacement pump pack.
The MX3682 is a hydraulic pump pack used in a heavy StrongArm M30/M50 barrier system. Service should be performed by a qualified gate technician when the repair involves hydraulic pressure, pump pack replacement, biodegradable fluid service, valve diagnosis, motor/coupler service, cylinder movement, pressure behavior, heavy barrier arm movement, or unknown prior modifications.
Do not bypass hydraulic controls, relief valves, brake valves, flow controls, controller protections, vehicle detection, safety devices, disconnects, or barrier safeguards to keep the system operating. If the barrier arm lowers unpredictably, will not hold position, binds, leaks, or cannot be controlled safely, the system should be inspected before continued use.
The HySecurity MX3682 is a 3.1 GPM biodegradable hydraulic pump pack for select StrongArm M30/M50 barrier arm applications with 20-24 ft clear openings.
MX3682 is commonly listed for StrongArm M30/M50 applications with 20-24 ft clear openings, but fitment should still be verified by operator model, serial number, and current HySecurity parts diagram.
No. MX3682 is the biodegradable-fluid 3.1 GPM pump pack for 20-24 ft applications. MX3613 is the related standard-fluid 3.1 GPM pump pack for 20-24 ft applications.
No. MX3682 is not the same as the M30/M50 NP no-power pump packs. NP versions such as MX3687-01, MX3687-02, MX3688-01, and MX3688-02 are different configurations.
Common listings note that MX3682 ships with two 3/8 inch hoses, 1/4 inch quick disconnects, and a motor coupler. Current package contents should still be confirmed before ordering.
Check hydraulic fluid type, fluid level, fluid condition, hoses, fittings, motor coupler, motor operation, manifold valves, cylinder condition, arm hardware, and whether the barrier arm moves freely before replacing the pump pack.
Yes. This repair involves hydraulic pressure, biodegradable hydraulic fluid, pump pack service, motor/coupler alignment, heavy barrier arm movement, and safety testing, so it should be handled by a qualified gate technician.
