Detailed description

T2 12V grįžtamasis siurblys Raymarine (kataloginis numeris M81121) skirtas valdomiems laivų vairavimo sistemoms Raymarine. Skirtas daugiausia laivams su esamu hidraulinio vairavimo įranga, bet gali būti naudojamas ir mechaninio vairavimo sistemose, derinant su antruoju vairavimo cilindru. Palyginti su Type 0.5 (50-110 cc) ir Type 1 (80-230 cc) modeliais, Type 2 siurblys siūlo didesnę cilindro talpą – 230-350 cc, skirtą vidutinio dydžio ir dideliems vairavimo sistemoms, tuo tarpu Type 3 (350-500 cc) skirtas didžiausiems cilindrams.

Techninės charakteristikos ir integracija

Šis siurblys varomas 12 V nuolatinės srovės nuolatinio magnetų variklio ir turi valdomus grįžtamojo srauto vožtuvus, kurie neleidžia grįžti rankiniam vairavimo sistemai arba vairo apkrovai. IP67 apsaugos laipsnis leidžia varikliui būti atspariamiam vandeniui, o jį galima nuimti nuo siurblio neįleidžiant oro į hidraulinę sistemą ir nepraleidžiant skysčio. Siurblys suderinamas su subalansuotais arba nesubalansuotais cilindrais ir gali būti naudojamas sistemose su slėgio rezervuaru.

Galingumas ir atitikimas

Raymarine T2 grįžtamasis siurblys pasiekia 2300 cc/min srautą (tuščia eiga) ir atlaiko 55 barų maksimalią tarpinę slėgio apkrovą (12 V). Tipinis srovės stipris 12 V ir 55 barų slėgyje – 24 A. Visi jungimo anga yra 1/4 colio BSPP tipo. Skirtas montuoti po deniu, apsaugotas naudoti variklio skyriuje. Produktas atitinka direktyvas CE 2004/108/EC (EMC), EN60945:2002, 94/25/EC (RCD), EN28846:1993 ir 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 powerboats equipped with hydraulic steering. With a cylinder capacity of 230 to 350 cc, it is ideally suited for mid-sized vessels, offering a balance between power and footprint. It differs from the Type 1, which is 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 required when handling fittings and hoses to prevent system contamination, which could impair the function of the integrated check valves. For optimal EMC performance, connect it to a dedicated battery separate from the engine starter battery. While the installation manual is comprehensive, installation by a Raymarine-certified technician is strongly recommended to ensure system safety and steering performance.

This pump is not intended as a replacement for the primary steering system, but as an assist for autopilot operation. 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 bleed, 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 compatible hydraulic ram capacity for this Raymarine Type 2 pump?

The Raymarine Type 2 reversible pump is designed for medium to large steering systems, handling a ram 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 at 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 hydraulic rams and 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 prevent vibrations that could damage the pipes, it must be mounted on a solid structure. It is critical 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.
