HOME /  Prista oil distributor for lub. oil


 H.H. Brothers Maritime ltd. is direct representative of  Prista Oil ltd. and  arranging supply of vessels with Lubricant Oils as follows:


PRISTAŽ MARINE C  oils are designated for low-speed crosshead diesel engines with circulation lubrication, that is to say a closed system intended to lubricate crankshaft bearings, camshaft bearings, etc. PRISTAŽ MARINE C  ensure rust and corrosion protection at long idle times or downtimes, they wash away wear debris, dirt, scales and oxidation products. These oils do not form stable emulsions with occasionally entrapped water and at last but not least important they prevent deposit formation on the oil cooled surfaces of piston bottom, oil pipelines and crankcase walls. PRISTAŽ MARINE C  oils ensure practically unlimited service life. They are formulated in three SAE viscosity grades: 20, 30 & 40 and with total alkalinity of 6 mg KOH/g.

PRISTAŽ MARINE CM oils are recommended for the other type of low-speed marine engines with the so called centralized forced lubrication of the pistons - open system. Only fresh oil enters the cylinders and it almost completely bums there. Just very small quantities run down the cylinder walls into the under piston area and there they are periodically drained as waste. PRISTAŽ MARINE CM completely meet the basic requirements towards marine oils for high output marine engines burning residual fuels (of high sulfur contents) namely very high TBN - about 70 mg KOH/g and proper thickness - SAE 50.

Prista Oil EAD recommends the following types and grades of lubricants for the other marine diesel engines, namely: medium-speed two-cycle and four cycle, high-speed four-cycle trunk-piston, depending on sulfur contents of the fuel they bum.

All products conform to API CF and meet the requirements of the major manufacturers of heavy loaded marine diesel engines such as: Pielstick, MAN - B&W, MAN Augsburg, New Sulzer Diesel, Wartsila etc.

We also have a special type marine oil PRISTAŽ MS 9250It is designated for lubrication of diesel engines that call for oils conforming to the Military Specification MIL-L-9000H. The high alkalinity of the oil allows its problem-free application in engines burning fuel with substantially high level of sulfur.

The following Prista brand lubricants are suitable for application in marine engines demanding motor oils of such quality and grade

PRISTAŽ SHPD 15W-40 - Conforms to API CI-4/CH-4/CG-4/CF-4/SL, ACEA E7/A3/B3/B4-04, approved against MB 228.3; MB 229.1, MAN 3275, Volvo VDS-2, RVI RLD, RD-2.DHD-1, Mack EO-M Plus, Caterpillar ECF 1, Cummins CES 20 072/1/6/7/8 & ZF TE-ML 07C/04C. This oil is also fit for application in the Detroit Diesel two-cycle diesel engines where the manufacturer recommends the application of API CH-4 performance level lubricant.

PRISTAŽ Leader TD 15W-40 - Conforms to API CG-4, CH-4/ SJ, ACEA E2-07; E2-04, approved against MB 228.1; MB 229.1,MAN 271, MACK EO-M Plus, Volvo VDS, Allison C^, MTU Type 1, Cummins CES 20071, Cummins CES 20076, Caterpillar ECF1, ZF TE ML 07C/04C, Renault RD/RD-2.



Besides the a.m. primary lubricants, the following supplementary lubricants are also suitable for marine applications:

Turbine Oils

Turbine oils PRISTAŽ ŇĐs 32, 46, 68They are intended for lubrication of water, steam and gas turbines demanding oils of the following ISO 6743-5 categories: TSA & TGA accordingly. They are also suitable for lubrication of the associated with the turbines equipment and governing systems. These oils can be used in circulation systems, different types of lubricated bearings, from lightly to medium loaded assemblies and in hydraulic systems with low to moderate pressures.

They meet the requirements of ISO 8086 type AR, DIN 51515 - Part 2, GENERAL ELECTRIC GEK-28143A TYPE I, II, III, SIEMENS TLV 901304, ALSTOM NBA 50001, ALSTOM HTGD 90 117 V 0001 T.
