DESIGN |
| The designs of our pumps are uncompromising with
engineering features typically only found in much larger and more expensive
units. Simple and efficient, our two-line system does not require "pressurized
air" to operate, and features a precision-made, ultra smooth, non-pulsating
axial piston pump design, with a roller-bearing squash plate. These pumps
easily adapt to most any non-power-steered vessel from 18 to 70 ft in
both recreational and commercial applications. |

FEATURES |
 |
Hydraulic Valve
Block - Extra Heavy Duty Aluminum billet machined valve block
with standard 1/4" NPT threads allow simple and easy connections to hydraulic
lines. No "funny" adapters needed or prone-to-crack "pot-metal" castings.
All pumps have a built-in internal relief valve for total system protection.
Output Ports - Unique dual outputs that allow simple
two-station and/or autopilot hook-up eliminating an external "T".
Lock-Valves - Built-in hydraulic lock valve allows any
number of stations with automatic station change-over and eliminates
un-wanted rudder feedback.
Pump Shaft - Oversized 22mm diameter stress relieved non-magnetic
Stainless Steel in both standard and extended lengths. Industry standard
3/4" steering wheel taper with common straight key design. No more lost
woodruff keys and allows easy sleeve adaptation to 1" bored steering
wheels (available Seafirst adapter).
Pump Shaft Seal - Externally replaceable industry standard double
lip oil seal.
Bearings - Unique needle roller bearing support for
steering shaft only seen in much larger pumps or more expensive designs.
Housing design - "O-ringed" sealed case with large built-in
reservoir. Vented and non-vented caps allowing horizontal or vertical
mountings, multiple upper & lower stations, and remote reservoirs (if
desired), with no gaskets to leak or deteriorate.
Case Material - Made from LUMID GP-2330A - An Engineering Grade
Glass Reinforced Copolymer developed by LG Chemical Corporation. Impervious
to saltwater environment with no more bubbling coatings or corroding
pot metal cases.
Hydraulic Oil - Multiple fluid compatibility as SEAFIRST
pumps operate on both Dextron ATF or other common hydraulic, aviation,
or steering oils meeting MIL-H-5056. We recommend ATF for hot climates
and the lighter Mil-Spec oils for colder climates. Mixing these oils
is a non-issue with all SEAFIRST pumps or hydraulic cylinders. |
