Hydraulic H.F. Units

Hydraulic Electro-Pump Units with Fixed Flow units are mainly designed for large pleasure boats, fishing and work crafts. Owing to a very strong construction, large oil tanks, high reliability of the pumps and distributors and to the easily accessible external mounting of elements connected with flexible tubes, these devices are the leaders on the market in the field of hydraulic electro-pump units.

Power Packs with Electrovalves

Hydraulic Power Packs with Adjustable Flow (non reversible) in 12 or 24 V for pleasure, fishing and work boats. They are fitted with an electro-distributor and an oil reservoir. Flow adjustment is done through a screw which allows accurate regulation of the time required for lock to lock displacement.

Reversible Power Packs for Double Rod Cylinders

Hydraulic reversible Power Packs with adjustable flow in 12 or 24 V for pleasure, fishing and work boats. They are reversible by changing the polarity on the motor terminals. Flow adjustment is done through a screw which allows accurate regulation of the time required for lock to lock displacement. These power packs are fitted with lock valves.

Reversible Power Packs for Single Rod Cylinders

Hydraulic reversible Power Packs with adjustable flow in 12 or 24 V for pleasure, fishing and work boats fitted with a single rod cylinder (unbalanced cylinder on outboard or stern-drive motors). They are reversible by changing the polarity on the motor terminals. Flow adjustment is done through a screw which allows accurate regulation of the time required for lock to lock displacement. These power packs are fitted with lock valves.

For boats equipped with a hydraulic steering, it will be necessary to determine:
– The volume of the steering cylinder (take the biggest volume in case of a single rod cylinder)
– Available voltage on board (12 VDC, 24 VDC, etc.)

For planing or semi-planing hulls, the power pack will be selected in function of its flow rate so that the steering cylinder will run its complete stroke within 10 to 12 seconds.

For displacement hulls, the power pack flow rate must enable the steering cylinder to run its complete stroke within 15 to 17 seconds.
Examples:

• Speed boat, planing hull with a 239 cc cylinder – Available voltage 12 VDC60 seconds (1 minute)
  —————————-
  12 seconds (required time) x 0.239 litre (239 cc) = 1.195 litre / minute
  The flow rate of the required power pack will be 1.19 litre / minute, therefore we will select a reversible power pack with adjustable flow rate type RV2 (12 V)
  
• Fishing or work boat, displacement hull with a 2,307 cc cylinder – Available voltage 24 VDC60 seconds (1 minute)
  —————————-
  15 seconds (required time) x 2.307 litre (2307 cc) = 9.228 litre / minute
  The flow rate of the required power pack will be around 9 litres / minute, therefore we will select a power pack type HF 1.5 – 9 (24 V)

LS power packs and linear drives for autopilots are perfectly adapted to the requirements of various applications, such as pleasure boating, coastal or deep sea navigation, workboats, professional or recreational fishing, sailing and power boat competition.

They are easy to install, state of the art machine finished and made to withstand the demanding marine environment.

You can easily select the best suited system for your boat within a wide range of equipment.

Our systems carry a 2 year warranty and are fully compatible with all major brands of autopilot electronics available on the market today.
