Tæknileg einkenni og innleiðsla

Púmpan er knúin af 12 V DC rafsegulvél með fastum segul og hefur stjórnaðar afturstreymisventil sem hindra afturstreymi í handstýringu eða stýrisúlu. Með IP67 verndarstig er rafsegulvélin vatnsheld og getur verið fjarlægð úr púmpunni án þess að loft komist inn í vökvakerfið eða vökvi leki. Hún er samhæfð jafnvægis- og ójafnvægisvélbúnaði og getur verið notuð með þrýstihólfakerfum.

Afköst og samræmi

Öfugpumpan T2 frá Raymarine hefur hámarksflæði upp á 2300 cc/mín (tóm) og þolir hámarksþrýsting upp á 55 bar (við 12 V). Við 12 V og 55 bar er venjuleg straumur 24 A. Öll tengipunktar eru 1/4 tommu BSPP. Hönnuð fyrir uppsetningu undir þilfari og er vernduð fyrir notkun í vélahólfum. Þessi vara uppfyllir kröfur ESB 2004/108/EC (rafsegulþol), EN60945:2002, 94/25/EC (RCD), EN28846:1993 og EN ISO 10592:1995.

« Technical analysis of the Raymarine T2 12V hydraulic pump »

Raymarine’s reversible Type 2 hydraulic pump, model M81121, is a key component for integrating an autopilot system on sailboats and motorboats equipped with hydraulic steering. With a cylinder capacity of 230 to 350 cc, it is ideally suited for mid-sized vessels, balancing power and footprint. It differs from the Type 1 (more compact, 80–230 cc) and is designed for applications where the Type 3 (350–500 cc) would be oversized.

This pump must be installed below deck on a rigid structure to minimize vibrations that could reduce the lifespan of hydraulic hoses. Absolute cleanliness is essential when handling fittings and hoses to prevent system contamination, which could impair the function of the built-in check valves. For optimal EMC performance, connect it to a battery separate from the engine starter battery. While the installation manual is detailed, having a Raymarine-certified technician perform the installation is strongly recommended to ensure system safety and performance.

This pump is not intended as a replacement for the primary steering system but as an assist for piloting. Its use is discouraged in confined areas where flammable materials are present. Its design with a separable motor simplifies maintenance without requiring a full hydraulic circuit purge, a practical long-term advantage.

Frequently asked questions

Need help? Contact us

What is the Raymarine T2 12V reversible pump used for?

The Raymarine T2 12V reversible pump (reference M81121) is designed to operate the steering mechanism of a vessel as part of a Raymarine autopilot system. It is primarily intended for boats equipped with an existing hydraulic steering system. It can also be used on mechanically steered vessels in combination with a secondary steering cylinder.

What is the hydraulic cylinder capacity compatible with this Raymarine T2 pump?

The Raymarine Type 2 reversible pump is designed for medium to large steering systems, handling a cylinder capacity of 230 to 350 cc (14 to 21.4 cubic inches). For reference, the Type 0.5 handles 50-110 cc, the Type 1 handles 80-230 cc, and the Type 3 handles 350-500 cc.

What are the electrical specifications of the Raymarine T2 12V pump?

This pump is powered by a 12 V DC permanent magnet motor. It is designed to operate with a typical current draw of 24 A at 12 V and 55 bar pressure. All pump ports are 1/4 inch BSPP type.

Is the Raymarine T2 pump compatible with all types of rams and hydraulic systems?

Yes, the Raymarine T2 pump is compatible with balanced or unbalanced rams. It can also be used with pressurized reservoir systems. Its design includes pilot-operated check valves that prevent feedback from the manual steering system or rudder load.

Where and how to install the Raymarine T2 reversible pump?

The T2 pump is designed exclusively for installation below deck. For optimal performance and to avoid vibrations that could damage the pipes, it must be mounted on a solid structure. It is crucial to install it away from heat sources, excessive vibrations, and fumes, and not to mount it in confined areas containing flammable materials. Additionally, it must be installed above the waterline. Absolute cleanliness is essential when installing hydraulic systems to prevent dirt particles from affecting the operation of the check valves.

Is the Raymarine T2 pump waterproof?

Yes, the Raymarine T2 reversible pump motor has an IP67 protection rating, making it water-resistant. This design allows you to remove the pump motor without introducing air into the hydraulic system or causing fluid leaks.
