HySecurity MX3682, PUMP PK,RPLCMT,3.1, BIODEG SAM
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.
What This Pump Pack Does
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.
Compatible With
This pump pack may be used with the following applications where the current HySecurity parts diagram confirms MX3682:
- Select HySecurity StrongArm M30 barrier arm applications with 20-24 ft clear openings and biodegradable hydraulic fluid configuration
- Select HySecurity StrongArm M50 barrier arm applications with 20-24 ft clear openings and biodegradable hydraulic fluid configuration
- Powered StrongArm M30/M50 hydraulic panel repairs where the parts diagram lists MX3682
- Repairs where the original pump pack is marked, listed, or cross-referenced as MX3682

Important Compatibility Warning
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.

Technician Note
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 operator is a HySecurity StrongArm M30 or StrongArm M50 application.
- The clear opening is 20-24 ft.
- The application is the powered M30/M50 pump pack configuration, not an NP no-power hydraulic panel.
- The system uses the biodegradable hydraulic fluid configuration.
- The current HySecurity parts diagram lists MX3682 for the pump pack position.
- The included 3/8 inch hoses, 1/4 inch quick disconnects, and motor coupler match the service requirement.
- The motor, coupler, manifold, reservoir, hoses, fittings, valves, cylinder, and hydraulic fluid match the original configuration.
- The issue is not caused by low fluid, contaminated fluid, air in the system, valve trouble, hose restriction, motor failure, coupler damage, cylinder bypass, or arm binding.
- The package contents include the pump pack, hoses, quick disconnects, coupler, and any hardware needed for the repair, or related parts are being ordered separately.
- The system has not been modified with non-original hydraulic components, hose routing, or pump pack hardware.
Installation and Service Notes
- Disconnect power and follow proper lockout procedures before servicing the barrier operator.
- Relieve hydraulic pressure according to the operator service procedure before removing hoses, fittings, valves, or pump pack components.
- Mark all hydraulic hoses and ports before disassembly to prevent crossed lines during installation.
- Cap or protect open hydraulic ports and hoses to keep dirt, water, and debris out of the system.
- Use only the correct fittings, seals, couplers, hoses, and approved biodegradable hydraulic fluid for the StrongArm M30/M50 hydraulic circuit.
- Do not mix biodegradable and standard hydraulic fluid unless the system has been properly serviced and verified for the intended fluid type.
- Do not adjust or defeat brake valves, relief valves, flow controls, pressure controls, or hydraulic safeguards without following HySecurity service procedures.
- After installation, check for leaks, correct pump operation, smooth arm movement, controlled raising and lowering, and proper hold behavior.
- Test all required safety devices, vehicle detection, access-control inputs, arm movement, limits, and operator protections before returning the barrier to service.
Professional Advisory
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.
