THE name Stratoline is given to the latest designs in the range of Alemite lubrication equipment marketed by Stewart Warner Ltd. Mobile lubricating pumps for grease or lubricating oil with this name have three types of pump with ratios to cover the different viscosities commonly used.
With a 70 to I ratio the units are suitable for light-bodied chassis grease and multipurpose lithium-base lubricant, and with a 50 to 1 ratio fibrous greases can also be used. For gear oil and engine oil, a 4 to 1-ratio pump is available. In all cases the air supply can be up to 150 p.s.i. Features are that the air motor is sealed, the priming chamber is compact (so preventing air pocket, trouble) and the air-valve trip mechanism has a double toggle which prevents the pump from binding or stalling. The Stratoline mobile units are in a modern style with the lubricant drum covered by an enamelled casing. A matching oil-drain unit is also made.
In a similar range of models there are the Alemite Visi-drum mobile lubrication units without an outer casing, the pump unit and cover simply locating on top of the drum, which stands on a base having four castors, The same three pump units—standard, 70 to 1; high pressure, 50 to 1; and low pressure, 4 to l—are used to cater for different grades of lubricant, and there is also a matching oil-drain unit.
A smaller greasing unit is the SevenEleven, which is essentially a container with pump and cover, carried on a two-wheel trolley. The container will accept all smallsized standard kegs or pails, or 70 lb. of bulk lubricant. A grease pressure of 45 times that of the air pressure used is given. There is also the 4580 Economic mobile grease unit, which has a container sufficient for 28 lb. of grease or 5 gal. of lubricant mounted on a two-wheel trolley, and a pump Unit also with a 45 to I ratio.
Accessories available for the units include a removable follower plate designed for pumps suitable for use with 112to 120-1b. grease kegs, and there are various designs of delivery gun. There is also the Model 2700 Typhoon Auto Repeater, which is an airoperated hand greaser (the grease is carried in a small container below the gun), the air motor having a ratio of 65 to 1. The 2700 can be used for gear oil and light grease with the input air pressure 60 p.s.i., and heavy and fibrous greases if 100 p.s.i. is available, The pumps used on the mobiles are also incorporated in the pumping systems used for Stratoline wall-mounted installations supplied by Stewart Warner. Any number of pumps, delivery outlets and delivery meters can be built up into the type of installation required for particular needs. A frame designed by Stewart Warner provides easy fixing for the individual flush-fitting units and, at the rear of the installation, hose reels are mounted on runners.
Hose reels are also marketed by the company as individual units or as a battery. Three forms are available, uncased, with a circular casing, or with a de-luxe casing which covers the whole reel and fixing plate. Completing the range of Alemite lubrication equipment are various types of lubrication bucket which are essentially hand pumps for chassis greasing or oil delivery. Highpressure units can supply pressures of up to 6,000 p.s.i., whilst a gear-oil dispenser has an output of one pint per 12 strokes. There are also various adapters and connector heads for oil and grease lubrication.
