The single point lubricator (SPL) is an automatic lubrication method widely used in modern manufacturing operation. Since their introduction more than 50 years ago, SPLs have undergone an extensive improvement process. Original spring type lubricators (old compression grease cup) were replaced by gas charged automatic lubricators, and battery-operated electromechanical lubricators are now replacing gas charged lubricators. These new SPLs offer more and more flexibility and reliability than their predecessors have. Here are the benefits and advantages of electromechanically operated SPL over traditional gas charged model.

Pulsarlube M, one of the most sophisticated electromechanical SPL is designed to ensure reliable lubrication and cut lubrication cost by an advanced electronic control mechanism. It consists of a vertical feed pump, motor/gear set, and Microprocessor control system, which makes outstanding operating pressure available (20Kg-f/cm², 280psi, Typical). The lubricant is supplied in either 125cc or 250cc Pulsarlube grease pouches, which are replaceable along with an Pulsarlube battery pack. Pulsarlube M offers 6 optional dispensing rates from 1/2(Half) to 12(Twelve) months in a single unit.

ㆍ	Pulsarlube M is designed to last through many years of use. Over the years this can add up to substantial savings over the cost of manual lubrication and disposable one time use lubricators (mostly traditional gas charged products), while providing assurance of the highest quality of lubrication achievable. Pulsarlube M Service pack consists of grease pouch (125cc or 250cc), a battery pack (4.5V Alkaline), and disposable dust cover.

Note : Pulsarlube M grease pouch and battery pack must always be changed at the same time. It is mandatory to ensure the reliable operation of unit.

Pulsarlube M unit has excellent remote installation capability while traditional gas charged SPL suffers. Sometimes space restrictions will not allow a direct mount, angle mount or extension mount. In other circumstances, small fittings may not be suited to direct mounting due to thread weight limitations. It is also true there are many applications where access is hazardous or inconvenient, contamination or harsh environments present. Where this occurs, the use of remote mount is required.

It is ALWAYS preferable to minimize the length of remote mounting. Pulsarlube M units should be mounted as close to the bearing point as possible.

Remote Installation Kit consists of :

1. Pulsarlube M Unit (125 or 250cc)
2-4, 7. Mounting Bracket Assembly (Red circled)
5. Pipe connector (1/4” or 1/8”M)
6. Tube Fittings (at both ends)
8. Nylon Tubing 6mm O.D. (Pre-filled)

* Refer to figure 1: Remote Installation of Pulsarlube M unit


	Multi-point Use
For applications where many lube points existing in close proximity, Pulsarlube M can be used as automatic lubrication system of up to 8 points using progressive divider block. System Elements : 1. Pulsarlube M Unit (125 or 250cc) 2-6. Mounting Bracket Assembly (Red circled) 7. Pipe connector (1/4” or 1/8”M) 8. Progressive Divider Block (4 to 8 ports) 9. Tube Fittings (at both ends) 10. Nylon Tubing 6mm O.D. (Pre-filled)
* Refer to figure 2: Multi-point use of Pulsarlube M unit using Progressive Divider Block (up to 8 ports)

General Guideline

1. Keep in close proximity to lube points.
2. All elements should be pre-filled with same or compatible grease prior to installation.
3. Recommend using NLGI #1 grease for Multi point use.

Typical Application

◎ Bearings

Typical lube points for SPL are :
1. Taconite seal lubricant feed point
2. Housing, bearing &seal lubricant feed point
3. Bearing central lubricant feed point
4. Housing, bearing &seal lubricant feed point
5. Taconite seal lubricant feed point

◎ Electric Motors

Electric motor lubrication is ideally suited to the SPL concept. However, electric motor bearings are lubricated less frequently than other bearing types. Over lubrication can result in greater problems than under lubrication. When Pulsarlube M unit is used on electric motors, ensure to follow manufacturers’ recommendation and that the bearing housing has a grease vent port.

◎ Pumps

Pumps are one of the most common applications for SPL. They are subject to high water, chemical and corrosive material contamination. It is mandatory to maintain the constant flow of grease to seal out contaminants. If the seal can be effectively lubricated and purged by use of Pulsarlube M, the bearing failures and maintenance budget can be dramatically reduced.

◎ Conveyors

Conveyors are widely used in cement, mining, food/beverage, and brewery industry. They are key elements to keep the high productivity and efficiency of manufacturing operation and subject to heavy dust/dirt, high water, chemical and other corrosive material contamination. Pulsarlube M unit is typically fitted to the bearing housings to lubricate bearings.

The typical arrangement is ;
One bearing and two seals per drive side housing.
One bearing and one seal per non driven housing.
(Housings are generally fitted with labyrinth or taconite type seals.)

◎ Agitators & Shafts

Mainly, Agitators are for vertically mounted shafts to manufacturing, process and storage tanks. In the pulp and paper industry, they are for horizontally mounted shafts to drive paddles. Pulsarlube M units are fitted to the bearing housings to lubricate the bearings. Applications can be subject to high water, chemical and corrosive material contamination. Pulsarlube M provides a constant flow of grease to seal out contaminants.

◎ Journals(Plain Bearings)

Plain bearings operate on a total loss system. They are typically used on auger shafts, gear support shafts or for power transmission. Applications can be subject to heavy load, high water, chemical and corrosive material contamination.

When Pulsarlube M unit is used, please consider that Journal bearings usually require a higher lubricant volume than anti friction bearings of the same diameter.

◎ Sheaves

Sheave applications are diverse and can include wire rope applications in Mining equipments, Elevators, Cranes, Hoists, and Cable belts etc. The working environment to these applications can have access restrictions and heavily contaminated environments. Pulsarlube M unit is used to lubricate sheave support bearings and also to apply lubricant to wire ropes.

Understanding Backpressure

The pressure generated is a response to resistance to flow presented to the unit. The most common back pressure causes are:

Accumulation of deposits in bearings or passages
ㆍSeals that will not permit flow
ㆍLubricant feed ports between the unit and the bearing
ㆍFittings with small feed passages
ㆍLine pressure losses in remote mount installations

While impractical to do anything about the design of the bearing arrangement, Pulsarlube M units should be mounted as close to the bearing point as possible. The shorter the distance the grease is required to travel, the less back pressure presented by the feed passage. IF IN DOUBT, test backpressure with grease gun connected to pressure gauge prior to installation. This testing also makes sure to fill the grease passage with same or compatible grease.
