HySecurity MX001944, Pump Pack, SlideDriver 40
The HySecurity MX001944 is a replacement hydraulic pump pack for select HySecurity and Nice HySecurity SlideDriver 40 hydraulic slide gate operators. It is commonly listed as Pump Pack, SlideDriver 40 and current listings describe it as a 2.0 GPM, 60Hz replacement pump pack for compatible SlideDriver 40 systems.
The pump pack is the hydraulic power section of the SlideDriver operator. In compatible SlideDriver 40 operators, the electric motor drives the pump pack so hydraulic pressure and flow can be delivered through the manifold, valves, hoses, quick disconnects, hydraulic motor, and drive system. When the pump pack is worn, damaged, leaking, contaminated, or unable to build proper pressure, the operator may move weakly, stall under load, chatter, coast, start harshly, stop poorly, or fail to move the gate.
MX001944 should be selected by exact HySecurity part number and operator 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, brake valve configuration, and reservoir setup.
What This Pump Pack Does
The MX001944 pump pack supplies hydraulic pressure for compatible SlideDriver 40 gate operator systems. It works with the electric motor, motor-to-pump coupler, reservoir, valves, 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, contamination, 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 MX001944 is intended for select HySecurity / Nice HySecurity SlideDriver 40 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 arrangement, reservoir configuration, and current HySecurity parts documentation.

Do not assume MX001944 fits every HySecurity SlideDriver or SlideDriver II operator. HySecurity lists different replacement pump packs for different SlideDriver models, and those pump packs should not be treated as interchangeable without checking the parts diagram.
How MX001944 Differs From Other SlideDriver Pump Packs
HySecurity SlideDriver pump packs are model-specific. MX001944 should be used for SlideDriver 40 applications only where the parts documentation confirms the fit.
- MX001944: Pump Pack, SlideDriver 40.
- MX001943: Pump Pack, SlideDriver 15.
- MX001979: Pump Pack, SlideDriver 30F/40F.
- MX001977: Pump Pack, SlideDriver 50VF2/3, 60/50Hz, commonly referenced for pre-June 2017 models.
- MX4191: Pump Pack, SlideDriver 50VF2/3, 60/50Hz, commonly referenced for post-June 2017 models.
- MX4187: Pump Pack, SlideDriver 80.
- MX001981: Pump Pack, SlideDriver 200.
If the operator has had a previous pump pack replacement, motor change, hose update, or hydraulic retrofit, compare the installed pump pack configuration instead of relying only on the operator model name.

Important Compatibility Warning
MX001944 should be selected by HySecurity part number, SlideDriver 40 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 40 is weak, noisy, or will not move. First check the gate movement, drive wheels, hydraulic fluid level and condition, hose leaks, quick disconnects, hydraulic motor, relief valve behavior, motor output, motor coupler, and controller command. A good pump pack can look bad when the gate is dragging, the coupler is stripped, or the hydraulic system has a leak outside the pump pack.
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 properly before final installation.
Before Ordering, Confirm
- Confirm the needed HySecurity part number is MX001944.
- Confirm the operator is a compatible HySecurity SlideDriver 40 hydraulic slide gate operator.
- Confirm the operator model, serial number, and production configuration.
- Confirm the parts diagram lists MX001944 as the correct pump pack.
- Confirm the operator does not require a different SlideDriver pump pack such as MX001943, MX001979, MX001977, MX4191, MX4187, or MX001981.
- 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, relief valve, drive wheels, controller output, or gate drag.
- Confirm whether motor coupler, breather cap, 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, seals, and quick disconnects.
During installation, compare the replacement pump pack to the original before final assembly. Confirm motor coupling fit, motor shaft key placement, quick disconnect routing, breather cap location, 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 40 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, 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.
