UPDATE

Wartsila Diesel Introduces

A New Compact V8 Engine —Literature Available

The new compact high-perform- ance Wartsila Vasa 8V22 is the latest development of Wartsila Die- sel's Vasa 22HF engine series. This small, low-weight engine has an out- put of 1,160-1,400 kw (1,576-1,904 bhp) at 900-1,200 rpm. Although only recently introduced, the engine has already generated great interest, and the first Vasa 8V22 has already been sold for propulsion on a Dutch fishing vessel.

The low weight and small size of the Vasa 8V22 are the result of a design concept aiming at a powerful, compact V engine using high-quali- ty materials in the main compo- nents. The cylinders are arranged at a 60-degree angle. The engine is ful- ly balanced and suitable for resilient mounting. The nodular cast iron en- gine block is cast in one piece and combines thoroughly dimensioned channels and reinforcements to pro- vide rigidity. The result is a frame that maintains its shape and pro- vides a good basis for the efficient functioning of reciprocating and ro- tating parts.

The crankshaft, with hardened pins and journals, is forged in one piece. The shaft is highly rigid be- cause it is short. These features result in longer service life and greater reliability for both bearings and crankshaft. Monoblock nodular cast iron pistons with hardened ring grooves and the Wartsila-patented pressure-lubricated skirt ensure safe operation.

A pulse charging system with a high-efficient turbocharger provides

Cross section 8V22 good load-taking capacity and high performance at all loads. The UIC test shows a low exhaust gas tem- perature level, 475° C after the cylinder, at an engine output of 1,650 kw and all deviations within +/— 15° C. Moreover, the emission values of the exhaust gases are low.

A new type of generating set has also been developed by Wartsila

Diesel to match the compact engine design. This arrangement includes a flange-mounted alternator bolted to the engine front and to the welded oil sump. Mounting the alternator is easy because of a special coupling design that absorbs small shaft al- ignment divisions.

Wartsila Diesel, manufacturer of the Wartsila Vasa type engines, is a leading maker of medium-speed diesel engines. Wartsila Diesel com- prises the Vasa and Turku diesel factories in Finland, the Trollhattan factory in Sweden, the La Ciotat factory in France, as well as a fac- tory in Singapore.

With more than 4,500 diesel en- gines delivered to 45 countries,

Wartsila Diesel has a great deal of experience in both marine and land- based installations of various types.

Vasa 8V22 diesel engine and the new generating set. For free copies,

Cat Pumps Introduces

Corrosion-Resistant Line —Literature Available

Cat corrosion-resistant plunger pumps.

Cat Pumps Corporation of Min- neapolis recently unveiled a line of corrosion-resistant plunger pumps featuring aluminum bronze mani- folds and 316 stainless steel or Ni- tronic 50 wet-end parts. Durable ceramic plungers, preset lubricated seals, and unique internal porting are said to make these pumps prac- tically maintanance-free. The forged, nitrited chrome-moly crank- shaft gives them unmatched strength and hardness.

Single or multiple-pump installa- tions provide unlimited application versatility. These pumps provide the quality materials needed for such demanding applications as re- verse osmosis and saltwater/waste- water injection, or the flexibility and mobility for in-plant jobs such as central cleaning systems, sanitiz- ing, mold and conveyor cleaning, paint removal, or fleet washing. Sev- en models provide capacities rang- ing from 3.5 to 36 gpm, and pres- sures from 1,200 psi to 5,000 psi.

A complete line of pumps, parts, and complementary fluid controls is available through Cat Pumps' worldwide network of sales and ser- vice representatives.
