Swisher OEM Hydraulic Pumps | Horsepower 20-35 HP | For Zero-Turn Mowers & Tractor
DESCRIPTION
Power your Swisher commercial equipment with genuine OEM hydraulic pumps engineered for reliable, high-performance operation in demanding professional applications. This premium collection features three heavy-duty hydraulic pumps designed to deliver consistent flow rates from 16 to 22 gallons per minute, providing the hydraulic pressure needed to drive wheel motors, implement lifts, and auxiliary hydraulic systems on zero-turn mowers, commercial lawn equipment, and hydraulic-driven machinery.
The 16 GPM Hydraulic Pump (Model LS2002B - Part# 1003437) represents Swisher's premium hydraulic solution for commercial-grade equipment requiring robust, sustained hydraulic flow. This precision-engineered pump delivers 16 gallons per minute of hydraulic fluid circulation, providing the consistent pressure needed to power dual wheel motors on zero-turn mowers and heavy-duty riding equipment. Built to OEM specifications, this pump ensures perfect compatibility with Swisher's hydraulic drive systems while delivering the reliability that commercial landscapers and grounds maintenance professionals demand. The LS2002B handles continuous operation in high-heat environments, maintaining stable pressure output even during extended mowing sessions on large properties.
The 16 GPM Clockwise Rotation Pump (Model 17094) offers directional-specific hydraulic power for equipment requiring clockwise shaft rotation. This versatile pump matches the 16 GPM output of the LS2002B while providing the specific rotational direction needed for certain Swisher equipment configurations. The clockwise rotation design ensures proper hydraulic fluid flow through the system, preventing cavitation and maintaining optimal pressure to wheel motors and hydraulic implements. This pump is essential for maintaining manufacturer-specified performance on equipment designed for clockwise hydraulic pump operation.
The 22 GPM High-Flow Hydraulic Pump (Model 19166) delivers maximum hydraulic performance for larger commercial equipment and high-demand applications. With a nominal flow rate of 22 gallons per minute operating at 3600 RPM, this pump provides 37.5% more hydraulic capacity than standard 16 GPM units. The advanced dual-displacement design features low-pressure output of 16.22 ml/r and high-pressure output of 7.04 ml/r, allowing the pump to efficiently adapt to varying load conditions. The preset relief pressure of 4.5 MPa and working pressure of 21 MPa ensure safe operation while delivering maximum power when needed. This high-capacity pump is ideal for larger zero-turn mowers, commercial-grade riding equipment, and applications requiring auxiliary hydraulic power for implements like mower deck lifts, baggers, or hydraulic steering systems.
All three pumps feature precision-machined components that minimize internal leakage and maximize volumetric efficiency, ensuring every drop of hydraulic fluid contributes to usable power. The robust construction withstands high operating temperatures, contaminated hydraulic fluid, and the shock loads common in commercial mowing applications. Sealed bearing assemblies protect internal components from moisture and debris, while hardened drive shafts resist wear from constant high-speed rotation.
These hydraulic pumps are designed for equipment powered by 20-35 horsepower engines, with the 16 GPM models suited for 20-28 HP applications and the 22 GPM high-flow pump optimal for 28-35 HP power units. Proper engine horsepower is critical—undersized engines cannot maintain the RPM needed for consistent pump output, while these pumps ensure engines in the proper range deliver full hydraulic potential to drive systems.
Power Requirements: 16 GPM pumps require minimum 20-28 HP engines to maintain 3600 RPM under load. The 22 GPM high-flow pump requires 28-35 HP for optimal performance. Compatible with PTO-driven and engine-direct hydraulic systems on zero-turn mowers, commercial riding mowers, and hydraulic-drive lawn tractors.
