Ultraflex UP28F Helm Pump

ULTRAFLEX UP28F Helm Pump: Precision Control & Unmatched Durability

Upgrade your vessel’s command center with the ULTRAFLEX UP28F Helm Pump, the cornerstone of a reliable and responsive hydraulic steering system. Engineered for demanding marine environments, this front-mount helm pump delivers exceptional performance, safety, and longevity, ensuring you have absolute confidence in your boat´s handling whether you´re navigating tight marinas or cruising in open water. Experience the difference of a high-quality steering component designed to provide smooth, effortless control for a wide range of inboard, sterndrive, and outboard powered boats.

The UP28F is built around a core of robust engineering and intelligent design. Its compact, axial piston construction is the heart of its efficiency, providing consistent hydraulic pressure for immediate and precise rudder response. This design not only enhances the feel at the helm but also contributes to the pump´s overall durability and reliability under continuous use. Boaters will immediately appreciate the built-in lock valve, a critical feature that provides a positive rudder lock. This prevents rudder drift and eliminates the constant need for minor corrections, allowing you to set your course and maintain it with ease, significantly reducing fatigue on longer journeys.

Safety is paramount on the water, and the UP28F addresses this with an integrated relief valve. This essential component automatically protects your entire hydraulic steering system from over-pressure situations, which can be caused by sudden impacts on the rudder from waves or grounding. This protection safeguards your lines, cylinder, and the pump itself, preventing costly damage and potential loss of steering. The pump’s construction features a heavy-duty 3/4” tapered stainless steel shaft, ensuring a secure, corrosion-free connection to your steering wheel and exceptional torque transfer. Further enhancing its resilience, the unit incorporates a cast iron cylinder rotor, a material chosen specifically for its superior wear resistance and durability, promising a long service life even in the harshest saltwater conditions.
