Uflex UP28R Rear Mount Hydraulic Helm Pump

The Uflex hydraulic helm pump converts steering-wheel rotation into hydraulic flow for a compatible marine steering system. Its compact pump body, tapered steering shaft, internal valve system, and corrosion-resistant construction create the control point that sends fluid to the steering cylinder as the operator turns the wheel.

Built-in lock and relief valves on supported models help maintain positive steering control and protect the hydraulic circuit from excessive pressure. The pump is built to work with correctly sized steering cylinders, hoses, fittings, and hydraulic fluid, making helm displacement an important part of overall steering-system performance.

Confirm mounting style, helm displacement, steering-cylinder volume, wheel diameter, fitting type, hose size, and available dashboard clearance before installation. Follow Uflex instructions for plumbing, filling, and bleeding the system. Inspect all connections for leaks and verify smooth lock-to-lock steering before the boat is operated.

• The helm pump drives the steering cylinder as the operator turns the wheel.
• Internal valve systems help manage fluid movement within the steering circuit.
• An integral relief function on supported models adds hydraulic-system protection.
• Correct pump displacement, cylinder volume, hoses, and fittings determine system performance.
