HySecurity MX001981, Pump Pack, SlideDriver 200
The HySecurity MX001981 is a replacement hydraulic pump pack for select HySecurity and Nice HySecurity SlideDriver 200 hydraulic slide gate operators. It is commonly listed as Pump Pack, SlideDriver 200 in HySecurity replacement pump pack documentation.
The pump pack is the heart of the SlideDriver hydraulic drive system. In compatible SlideDriver 200 operators, the electric motor drives the pump pack so hydraulic pressure and flow can be delivered through the manifold, valves, hoses, quick disconnects, and hydraulic motor system. When the pump pack is worn, damaged, leaking, contaminated, or unable to build pressure, the operator may move weakly, stall under load, run inconsistently, coast, chatter, or fail to move the gate.
The MX001981 should be selected by exact HySecurity part number and SlideDriver 200 parts documentation. HySecurity uses different pump packs across SlideDriver models, and pump pack fitment can vary by model, production generation, motor arrangement, hose routing, quick disconnect layout, and valve configuration.
What This Pump Pack Does
The MX001981 pump pack supplies hydraulic pressure for compatible SlideDriver 200 gate operator systems. It works with the electric motor, motor-to-pump coupler, reservoir, valves, brake manifold, relief valve, hose kit, quick disconnects, hydraulic motor, drive wheels, and controller logic to move and stop the gate correctly.
This is a replacement pump pack, not a complete operator and not a full hydraulic system rebuild by itself. Replacing the pump pack can correct pump pack-related pressure, wear, or leakage problems, but it will not repair a failed electric motor, stripped motor coupler, leaking hose kit, damaged hydraulic motor, worn drive wheels, bad controller output, poor gate alignment, or a gate that is dragging or oversized for the operator.
Compatible With
The HySecurity MX001981 is intended for select HySecurity / Nice HySecurity SlideDriver 200 hydraulic slide gate operators where this pump pack is listed as the correct replacement. Compatibility depends on the operator model, serial number, production generation, electric motor, motor coupling, hose kit, quick disconnects, valve layout, reservoir configuration, and current HySecurity parts documentation.
- Select HySecurity SlideDriver 200 hydraulic slide gate operators where MX001981 is specified
- Select SlideDriver 200 pump pack replacement applications listed in HySecurity pump pack installation documentation
- SlideDriver 200 hydraulic systems using the matching pump pack, motor, coupler, hoses, quick disconnects, and valve configuration

Important Compatibility Warning
MX001981 should be selected by HySecurity part number, SlideDriver 200 model documentation, and the installed hydraulic configuration. Pump packs are not universal. Motor alignment, pump shaft design, coupling style, quick disconnect orientation, valve layout, reservoir setup, and hose routing must match the operator.
If the original pump pack failed, diagnose the cause before installing the replacement. A seized or overloaded system, contaminated hydraulic fluid, incorrect motor coupling installation, damaged quick disconnects, relief valve issues, dragging gate, or repeated overheating can shorten the life of a new pump pack.

Technician Note
A pump pack should not be replaced just because a SlideDriver 200 is weak or will not move. First check the gate movement, drive wheels, hydraulic fluid level and condition, hose leaks, quick disconnects, hydraulic motor, brake manifold, relief valve behavior, motor output, motor coupler, and controller command. A good pump pack can look bad when the gate is dragging or when the hydraulic motor or hoses are leaking.
When installing a replacement pump pack, pay close attention to motor-to-pump alignment and coupler engagement. HySecurity replacement pump pack instructions note that the pump pack shaft and motor coupling can be a tight fit and should be aligned without forcing the motor down or using a hammer.
Before Ordering, Confirm
- Confirm the needed HySecurity part number is MX001981.
- Confirm the operator is a HySecurity SlideDriver 200 hydraulic slide gate operator.
- Confirm the operator model, serial number, and production configuration.
- Confirm the parts diagram lists MX001981 as the correct pump pack.
- Confirm the operator does not require a different SlideDriver pump pack such as MX001943, MX001979, MX001944, MX001977, MX4191, or MX4187.
- Confirm the existing electric motor, motor coupler, and pump shaft configuration match the replacement pump pack.
- Confirm the hose kit, quick disconnects, valve layout, reservoir setup, and pump pack mounting match the installed operator.
- Confirm the hydraulic issue is not caused by the hydraulic motor, hose kit, brake manifold, relief valve, drive wheels, controller output, or gate drag.
- Confirm whether breather cap, motor coupling, motor shaft key, quick disconnects, valves, reservoir, fittings, threadlocker, anti-seize, instructions, and hydraulic fluid are included or must be ordered separately.
- Confirm the gate rolls freely and is not dragging, binding, sagging, or oversized for the operator.
Installation and Service Notes
Hydraulic pump pack replacement should be done with the operator disabled, the gate secured, and the hydraulic system handled according to the current HySecurity service procedure. Keep dirt, water, metal shavings, and debris out of open hydraulic fittings. Contamination can damage the new pump pack, valves, hydraulic motors, and seals.
During installation, compare the replacement pump pack to the original before final assembly. Confirm quick disconnect orientation, breather cap location, motor coupling fit, motor shaft key placement, valve layout, and mounting alignment. After installation, check hydraulic fluid level, inspect for leaks, verify pressure response, confirm smooth gate movement, and test all safety devices.
Professional Advisory
Replacing a SlideDriver 200 pump pack involves hydraulic pressure, moving gate parts, rotating motor/pump components, pinch points, electrical power, and pressure-rated fittings. A qualified HySecurity gate technician should handle this repair when the operator has repeated hydraulic failures, unknown prior repairs, heavy gate loading, electrical issues, or unclear leak/pressure symptoms.
Do not bypass covers, guards, limits, monitored entrapment protection, photo eyes, safety edges, brake systems, pressure controls, disconnects, or controller protections to make the operator run. The pump pack and hydraulic system should be repaired correctly and fully tested before the gate is returned to service.
